Exceptional sound quality. I was hesitant to pay for this due to poor experiences with other sip apps, and due to those experiences I figured some of these reviews were fake. I bought the app anyway and was amazed at how good the sound quality really is. The app includes some settings where you can adjust the microphone sound and that was what made this the best sip app for my Touch. I did not find those mic settings in any other sip app I tried. The sound quality is so good that it makes the Touch a viable wifi sip phone. I am using a Monster mic adapter purchased online just FYI. The push notification works fine but naturally if you leave your touch on all the time waiting for calls your battery will die sooner. That's not the fault of the app. Much thanks to the developers for what I consider to be the perfect voip app.

An amazing SIP client!. Like others in the App Store, I've tried numerous SIP clients. This softphone is definitely the best out there. Supporting multiple accounts that you can switch between instantly, I found the configuration of the app to be amazingly simple (especially since it includes configuration templates for nearly every major SIP provider...Vonage, Gizmo, Callcentric, voicheap, etc.). You can record a call directly on the phone (it even splits the recording into multiple tracks for you), place calls on hold, and can be used with your own VOIP setup (I'm using FreePBX on an Asterisk system). If I had to say anything negative, it would merely be that there are no options for different ringtones...but I'm sure that will be incorporated in a future version.

Work great!. It seems Customer Support is very effective. They resolved my issue and SIP Phone works nice and can here both way! Thanks so much! Earlier Review: This app doesn't work for Viatalk. It connects to services through SIP but when there's outgoing or incoming call, you don't here person. Basically incoming voice doesn't come. I contacted support a week ago but no fix yet!

Amazing SIP client!. I spent a lot of time looking for the best SIP client for my iPhone 4S and I can honestly say that I did the right thing choosing Acrobits. Even though it is not cheap compared to other apps, it is worth every penny. The number rewriting feature is amazing, I can't believe I ever lived without it. Most of the negative reviews seem to be from users without much VoIP or SIP knowledge. If you are an advanced user or just know enough to understand how to set up your SIP account and that the call quality depends on how good your network is, I definitely recommend this app. I don't think there is a better SIP client for iOS and they are always releasing new versions.

*** Dropped iPad support *** Works well with Asterisk / PBX in a Flash. Clearly abandonware - very unfortunate. —- **** How about an iPad formatted, universal version, upgrade? **** --- Upgraded to 5 stars for g.729 support, and a slew of additional, excellent enhancements - not to mention the developer keeps improving and supporting an excellent VoIP client. I wish I could give him more $$$ ;-) --- Upgraded to 4 Stars for supporting calling straight over 3G. Woohoo! ---- I run my own PBX in a Flash home and office PBX, and have been looking for an appropriate client on iPhone. This does the job, and it does it very well. Some suggestions for enhancements that would catapult this well into 5 stars territory: - support for the G.729 codec for even better quality. Yes, G.729 costs money to license - make it an in-app purchase. I would gladly pay an additional $5 or so for that feature. - allow customizing the ringtones - add custom quick-buttons for VM, for example. - aesthetic changes of the look and feel to bring it more in line with the native look of an iPhone phone app, than some avant garde retro design experiment (allow selection of different skins, to appease avant garde retro afficionados). Maybe make skins an in-app purchase. ;-) Do these, and a shining 5 stars, and more money, will be yours ;-)

Overall really great with a couple requests. I think this is the best SIP solution for the iPhone that I've seen and I think the call quality is excellent (I'm living in Rwanda and the calls over 3g to the States and the UK are really clear with Callcentric and Gizmo5--loads better than Skype). I'd recommend it for sure. I do have a couple requests: I'd love to be able to change the theme/background. I'm not so hot on the jungle theme. One thing I really like about Siphon is that the interface is similar to the default iPhone dialer. It would be great if that were an option here, although I suppose Apple may not want it to be similar. The ability to change the ringtone would also be wonderful--the current ringtone is a bit painful IMO. Ultimately I think it's the best solution so far (also maybe the most expensive for SIP) and I look forward to future updates. Edit: The latest update has fixed what were my major woes--gizmo5 incoming calls, dtmf problems, and crashing when calling callcentric voicemail. Life is looking up for sure. Tech support has been great when needed. I would definitely recommend this for anyone needing a sip solution on the iPhone.

Google Voice support removed. Still the best VoIP app available. For those of you who used the Google Voice feature it is no longer available. Not listed in the list of services and not listed on the help desk. A warning or update saying it was being removed would have been nice. Would have submitted a support ticket but the CAPTCHA on the support sure says "Invalid Site Key" and will not let me submit a ticket...

Best Sip phone on AppStore. Well, I have been using this app a quiet a long time and I realized that it has less then 5 star and got surprised. Incoming calls with Push is amazing. You get to use your VoIP on 3G flawless (maybe they are the first one offered this). I recently purchased Bria to see if there is anything exciting because of their star rating, but honestly nothing new or better. So I decide to write this review. I would highly recommend this app over other paid apps. I wish there was iPad specific version.

Makes my day so much easier with this app & Ring Central. I have a RingCentral account and with this app I can have a complete mobile office. I can be at the gym and take my calls. It make my job sooo much easier. I tried some of the other sip phone but this is the only one that I could find that would work with RingCentral. GREAT APPPPPP!!!

Good voice quality. Best SIP phone.. UPDATE: I'm changing my review and giving this phone a full five stars. This new version fixes all my complaints, plus adds some awesome new features. I've bought and tried all the SIP phones currently available at the app store. This one is the best one. The recording feature is done very well. I love how the recorded call is stored with your call history. Very clean interface. I'm using Gizmo5. Setup was very easy. The voice quality on this application is better than iSip (which I also bought). The interface is nice. Has a great feature to keep the Softphone running, so that you get incoming calls. (it prevents the iphone from sleeping, which is only helpful if the iphone is sitting on your desk plugged into some power. Otherwise, I'm sure it would drain the battery fast.)

Worked perfectly. This is the third native SIP application I tried. The first two would not connect to my VOIP provider so they were basically worthless for me. The acrobits VOIP application n was very easy to configure. It connected and registered to my VOIP provider's server immediately. Outgoing calls work flawlessly with excellent audio. I did not enable incoming calls so did not test the push notification. This is the SIP VOIP app to purchase.

Not bad. Still needs some work. Crashes on the first attempt everytime I register to a server. When I reopen and register with that same server it's ok. Call quality is fine over a good wifi connection. I wish the interface was more professional looking and more in line with the iPhone appearance. It would also be nice to dial a contacts number directly from the iPhones builtin contact list that syncs with my exchange server. AT&T is allowing voip over 3g now, so when will we see an update that let's us actually take advantage of that????

Support Needed. After purchasing this app many months ago I’ve finally tried it with the FlyNumber wwPBX. Believe I’ve set it up with proper account info, yet every couple days SoftPhone gives me a pop up message that my FlyNumber account has expired on the push server. Huh. I know my account hasn’t expired on FlyNumber, but who is running the server mentioned? Where do I get help on this? Giving SoftPhone the shadow of doubt, I’ve rated it 3 stars even though it hasn’t yet served for a single phone call.

Recommended, will save you much more than the cost of the app !. Easy to set up and use, reliable, great tech support, good sound, frequent updates with improvements. Shop around for a good inexpensive VOIP provider. Many out there. Don't hesitate to buy this app because it is much more expensive than others offered in the app store, this one is full-featured, reliable, and with great tech support.

Good Update, Could be better!. I'm not sure what this update brought for GV integration; it still seems the same as before. I'd still love to see proper support though! 1) Ability to automatically accept calls from your google voice number on a SIP account (perhaps only when the app is active and within a specified timeframe (20 seconds?) of dialing out using Acrobits' built in GV dialer, so you don't need to press accept after you pick the number to dial. 2) Using the same logic to link an outgoing Google Voice call and an incoming SIP call from your Google Voice number, have Acrobits label the SIP calls as outgoing and with the number that was dialed, instead of incoming and with your Google Voice number. Also, conferencing support as per groundwire would be nice... Maybe as a paid add on? Not sure why, but this update changed my color theme. Also, a recent update broke favorites.. not sure which one did that, but I had to re-add them all.

Works over 3G! Support is great.. I don't usually write reviews but this software has worked so well for me that I thought I should share some thoughts on it. One of the first things I consider when buying software or computer hardware is the customer/tech support that comes with it. Before clicking on the "Buy APP" button I emailed Acrobits a question about compatibility with my office IP PBX. I got a quick response and then decided to give it a shot. With just a few tries setting up some of the options I got it up and working. I did email Acrobits 2 more times with questions and both replies were timely and helpful. Just today I was surprised to notice that my IP calls were not only working over my wireless network but also over the 3G network while driving around town. This is great! I can now receive calls through my office IP PBX anywhere around town. Plus I can make calls to clients using my office phone lines. I read a lot of reviews that complain about the cost of apps. To me it comes down to what value you gain from using the application. The fact that I can answer my customer calls instead of them going into voice mail is worth $$$$ to me. I think my clients appreciate the fact that they can call me with questions and support and not have to wait for me to call them back. Great app, great support.

SIP client powerhouse. No client that i have found handles incoming calls very well. They either require the app to remain open and in the foreground and the screen cant be turned off, or they stay closed and load when a push notification arrives. Problem with this option is you most likely will miss the call because of loading time. This one uses the best of both options. While still not as reliable as a standard telephone it will pick up calls on a regular basis. I believe answering calls should remain a focus point for iphone sip client developers until it is perfected.

Contacts. I have an iPod touch 32 gig 3rd generation, and it seems that I'm the only one with this problem. All the contacts show up twice. I don't know why, but it doesn't affect the calls in any way. Ps. If you are one of those people who puts +1 or +36 or whatever before the number on all your contacts, it doesn't really like that

Can't receive calls if the app is not running. This app doesn't seem to work in the background, even though it claims to support iOS multitasking. As long as you can live with not having your phone ring when someone calls you, this seems like a great app. I bought it as a transition while I'm waiting for my Dead Gizmo5 dialin number to transfer to a new provider.

Great program and hoping for Universal upgrade to iPad. I have been using this great VOIP program on my iPhone and connecting to our company PBX system. I am hoping there will be a universal upgrade from this version to allow to take advantage the bigger screen of the iPad. I sure hope it will not be a full priced new version at the much higher prices we are seeing on the App store. BTW, this program as it sits works great on the iPad!

Would be nice, if DTMF and incoming worked. I like the UI for this app, but it seems to have a problem with receiving incoming calls when registered to my Cisco UC500 PBX. Outgoing calls are great, but when I try to place a call to the SIP phone, the call fails. I'm not talking about Push, but simply answering an inbound SIP call. Acrobits support initially seemed interested in helping but after I indicated that I had 5 other iPhone SIP clients with the exact same config working and only Acrobits was failing on inbound, and I provided SIP message debugs off the PBX, Acrobits support went quiet on me. Also, RFC2833 DTMF is broken, which Acrobits support acknowledged, but the most recent update didn't fix that either. I had high hopes for this SIP client, but it's non-functional for me at this point. iSIP is the only client that actually works completely, but the UI is ugly and the voice is laggy.

The best sip app for iPhone!. I tried 3 different sip apps ( all paid versions), and found this to be the best for call quality, consistency and speed on loading and registering my accounts. With the latest update (apparently, the bugs got sorted out for push notifications), I can answer my voip number even when the app is not open. Kudos! ****** now it works over 3g and edge **** I just tested it, great call quality - simply the best I must say.

Cisco Unified Callmanager 7. Tried other sip clients and had poor quality with calls. Got this one and used it to make some test calls and it worked very well. Was connected over a really crappy comcast connection to my agencies VPN server to Cisco Unified Callmanager 7 and it worked great. Haven't gotten push working yet. Only reason it got 4 stars. Hope to make it 5 sometime soon. Would love to see G.729 at some point. Can't wait for VOIP over 3G.

Best iPod Touch Voip Application. Where do I begin? I have used several of the paid applications for the iPod Touch and "none" of them worked well for me. For example: a) either I couldn't be heard, b) it took too long for the phone to sync up to the Wifi network, or a lot of other problems. All the other systems available on this site (although used) Free and Paid -- didn't work for me and were a waste of good money. I tried this and it worked great! I purchased (from the Apple Store) the Shure ($40) headset with microphone and it works absolutely great. I use it all the time and am extremely happy. Everyone is very clear and although I can hear other people fine I cannot hear myself but that's fine. This is work every penny but you need to buy an expensive headset with microphone (invest the money) because the Apple headphones feel bad and "hurt" every time I use them. I am in pain. Great purchase!!!!!

Acrobits. Excellent call quality. The g.729 add on is well worth the cost if you have a marginal wifi connection, nobody could tell that I was using VoIP. Google Voice integration is excellent and seamless. This is my back up phone when the cell signal goes away in a few of our buildings. Highly configureable settings, so if it doesn't work, it is most likely that the pre-set settings don't work for your case. Watch the videos, especially on how to configure google voice to work with your SIP account.

Crashes a lot. This application crashes extremely easy! Also, very often, when the person that i call answers, it freezes requiring me to restart the iphone! It seems the application has serious bugs! I use a generic sip account which works great with other providers! For this high price, i would not recommend at this point! Update: the problem was fixed by contacting tech support. The problem was with the 3g codecs! Now it works perfect. Would give 5 stars if it had call conferencing!

Acrobits Softphone. The update fixed the problem I was having making outgoing calls with my Vonage account. Thanks for that. But now if the app is running and my phone goes asleep and I then go back to this app after waking up my phone - it won't register on Vonage - sometimes. I have to shut it down completely from the running app tray. I'm beginning to think I was better off before Apple brought out this so called "multi tasking". Seems like it created a lot of issues with a lot of apps. I'm confident this is going to be a good app again. It just needs a few more upgrades. Old Review: Even by their own admission this upgrade really does not solve the basic problem which is the inability to receive calls when the program is not running in the foreground. Too bad. It would be so nice to be able to use my VoIP line for both outgoing and incoming calls. Push is not reliable. Work fine sometimes - other times it is several minutes before the puch notification arrives and by then the caller is gone. I am using a 3gs phone running ios4. My VoIP line if Vonage.

Great app!. The best SIP softphone ever. Excellent debug logs solved many problems (of my own making) related to NAT and codecs. Most feature-packed softphone available! Great work! I've even paid for your g729 codecs. I'm a SIP expert, and you've done it right! I almost left 4 star because it's not universal app for iPad. Please make this a universal app! Basic things like orientation have been lacking for a long time. Cosmetic, I know, but it isn't that hard. It's what's under the hood that counts, so I still gave 5. Great app nonetheless!

New Version Doesn't Work Well For Me At All. Just upgraded, and I hate to give a bad review, but this version is terrible. With the three last versions, I was able to receive calls (via Google Voice) with minimal problems. Without the app even on, I was able to receive a notification that someone was calling (Push Notification). If I accepted the call in time, it would open up the app, and I'd be able to take my call. I was very excited for iOs 4, and having the app run in the background, because I would be able to take calls faster without the app having to start up. However, with this version, incoming calls either ring once, but are "stale" by the time the application opens up, or there is no Push Notification at all! I am now not getting any of my incoming calls in time, and they are going to voice mail! This is a problem, as I don't get ANY cellular coverage in my work and living space, and this product was my answer to getting my calls via wifi. Please fix this problem, and reclaim a positive review from me. Thank you.

Daily use app. Useful and stable, my own pbx or public voip provider, especially NAT and encrypted calling , perfect app, bought it and you own it.

Great for GV + Gizmo. I use this app to get calls via google voice + gizmo on my ipod touch. I was worried that I had wasted my money because gizmo calls stopped working, but the latest version has everything working properly again. I get an audio ring alert and the popup with push notifications when I receive a call, even when my ipod is sleeping. My only complaint is that you have to open up the app every so often to continue getting push notifications of calls or it logs you our of gizmo.

Great support. I addressed a specific issue with our carrier (Softphone was not able to properly push incoming calls for Speakeasy VOIP) and Acrobits worked to resolve it. It's still not completely resolved (the calls received automatically goes into 'Hold'); however, I am able to use the client with pretty impressive call quality. I hope Acrobits will update w/ iOS4 support as well as complete resolution for Speakeasy soon.

The best SIP app I have ever seen. If you were like me, trying to figure out exactly which SIP app to look for, you found the right one here. It is true, you get what you pay for, and as far as I am concerned, I would gladly paid more if I had to for this app. The user interface was very well designed, and even up to the end of call beeps, it acts, sounds, and feels like a call being made on a regular wireless network. Even the audio is superb! Excellent audio frequency response on the TX audio, goes beyond C-message weighting curve! For me personally, I purchased this app for the use in areas where there might not be any cellular / PCS networks or while traveling out of the country. This app does a great job via wi-fi networks. I give this one 5 stars!

Don't upgrade yet if Callcentric is your provider. Upgraded to 4.0, looks pretty snazzy. However, while I can receive calls, I cannot make any thru my Callcentric VoIP provider. I've been online with them quite a bit today, and they are working with Acrobits, so hopefully this will be resolved soon, but if you use Callcentric, hold off on upgrading for a bit. My rating is artificially low for the moment, until this outbound calling issue gets resolved. I would rate the most recent, pre-upgrade version as a 4+, and hope to be able to offer a similar review with 4.0 once things work again. I'll update my review when it gets fixed. Nice to know, both Callcentric and Acrobits are responding quickly.

Works pretty good. I'm with a provider not listed on the sheet (VOIPYOURLIFE) but it seems to work none the less. The only issues noticed thus far are occasionally a dead line (though it won't hang up) and the occasional issue where the system won't call out, it just keeps on trying.... Overall though a very innovative product that works pretty darn good. Sound was good and conferencing codes worked fine. It's the best VOIP I tried and works great as long as you've got good wifi.

Best call quality, performance & reliability over VPN. search no more, check the other reviews, this is it. - works extremely well while connected via vpn. - very simple setup, works well with almost all SIP provider (tested on 13+ providers). - very good performance & reliability. - no other SIP client software in the app store comes close in call quality (tried almost all other SIP client apps).

Push Notifications are working!!. I bought this application for the push notifications, which work pretty well atleast for Gizmo5!! However my only Gripe is with the sound quality which could do with some improvements. The developers reply promptly and will guide you to address your concerns. The interface is good & the call recording feature is pretty good.

Great App!. Thank you, this is a great App!

Wast of money for me. I was trying to find an app that would let me record incoming and outgoing phone calls. A lot if the apps that claim to do that don't work at all. Found a website that mentioned this app and it had the best reviews. Also said it worked with Google voice. After downloading I tried to add my Google voice account but it continually told me my email and password were wrong; they weren't though. Frustrated I looked online to see if I was doing anything wrong and found out I HAD to have a SIP provider in order to use Google Voice with this app. It's probably my own fault I didn't realize this to begin with but everything else I read lead me to believe I could use this with only a Google Voice account if I chose to do so.

Excellent sound quality and push notifications. I've been very happy with the Acrobits Softphone app. The sound quality with Gizmo5 is excellent. The push notifications work well, too, and allow me to place a Google Voice call through the Google Voice web app and then pick up the call using the Acrobits push notification, which is handy in spots where I don't have cell coverage but do have access to the internet through Wi-Fi. The developer, who is responsive to questions and suggestions, has included the helpful feature of sending a push notification when the 24 hour login to Gizmo5 expires. Now that AT&T will allow VoIP over 3G, I hope that Acrobits will quickly post an update to allow the Softphone to work over 3G.

LumenVoice. We're a SIP provider and though this isn't as good as the quality you might get by using an Aastra, or Polycom phone, it works remarkably well. Nice easy to use interface makes it very user friendly. Very Nice!! USERS,keep in mind the network you use this on is a major factor for how well it works, some DSL's can't support quality SIP applications, I have a fair amount of bandwidth where I use this application which helps with performance.

New version fixed iOS 3.x crashing. Kudos to Acrobits devs for fixing the crashing on iOS 3.x fairly quickly. We've been using this app for a while and although I find startup is slower than iSIP (can be an issue on incoming push calls), the UI is more polished and the options are more than we will ever use. Voice quality is great as always. And the continued support for older versions of iOS is very welcome. Great product and my choice over other SIP applications.

Great app for travelers. This has proven to be immensely useful while traveling. While in the U.S. I have a local SIM with unlimited voice&data, and can easily point my "native" number to SIP calls, and have Acrobits Softphone notify me when I have an incoming call to my native cell - without hanging in the background and eating battery. Purchasing g.729 codec might seem to be expensive but 100% worth it. One missing feature I'd like to see is ability to set "route to SIP" in the app (e.g. for Megafon). Otherwise really appreciate the amount of work put in this truly useful app.

The best sip app for iPhone!. I tried 3 different sip apps ( all paid versions), and found this to be the best for call quality, consistency and speed on loading and registering my accounts. With the latest update (apparently, the bugs got sorted out for push notifications), I can answer my voip number even when the app is not open. Kudos!

All good. They fixed the really annoying camera issue! That was my only complaint. Great app!

Works very well. This app works very well for me. It would get 5 stars if it had visual voice mail and a full res iPad version. Great sound quality - better than a land line over wifi and good over 3G. This is the future of the business telephone IMO. With the aid of the good guys at my provider, Nextiva I was making calls within minutes on my iPad. Push works without a hitch. So far I am using speaker phone until I get a camera connection kit so I can use my headset.

Deceptive - does not support sms. The app description states this app supports sms. When I contacted their support to figure out how to use it, I was told it does not support sms. After I spent $7. I will be filing a complaint with Apple.

Great VOIP client. I’ve been using it for 2 years with no troubles. Plenty of features and configuration options. Push notification works well without requiring the app to run in background, so saving battery life. My voip provider, CallCentric, requires a “1” before all US phone numbers, and this app will automatically add that to any contact that doesn’t already have a leading “1”. Very convenient.

Awesome app for Google Voice/Gizmo users. If you are a Gizmo5 and Google Voice subscriber, this app will basically turn your iPad/iPod touch into a phone, realistically for outgoing calls. Add your Gizmo SIP account, then add your Google Voice account. This app will then use the callback method when you use the keypad, quickdial favorites or contact list (from within the app). No need to set up backgrounding. I've made free calls back to the United States from overseas using this app. It's not a telephone replacement (you can't dial 911 from this setup), however paired with a pay-as-you-go dumbphone, it's an effective way to cut your phone bill massively. This review is identical to the one I'm giving to Acrobits Groundwire. I didn't realize the two apps were so similar; for the scenario described above Acrobits Softphone is quiet adequate. There is no difference in call quality.

LOVE Softphone again!!!. The update now fixed the issue with Callcentric, thank you for the quick fix! This SIP program does everything I need plus extras that give it a big advantage over others including Skype. For one thing the ability to record the call is a huge bonus as often I need to review conversations for my work. Also I never could get my Callcentric SIP account to work with iPico or other iPhone SIP programs, Softphone worked without any problems. Lastly, I love that you can now use bluetooth with Softphone which is something Skype doesn't support and I seriously doubt that other iPhone SIP programs do at the moment. In a nutshell this is a well polished iPhone app well worth purchasing especially with all of the extras it includes. I like Callcentric and it works perfect with Softphone, highly recommended if you like saving money!!! This is by far my favorite VOIP program on either my Mac or my iPhone. No I don't work them, this is just a Grade A written program and does what I need it to do and well above that. Now with 3G support there's no reason to use AT&T for international calls, save your money and get this app.

ios 7 flat look?. Must have app but when is the new look coming?

Fantastic. Just work. I have setup 4 providers with each their own dialplan. Made calls over 3g wirh the g729 codec I purchase and have top quality voice. Highly recomended.

Wifi finder paid subscription. Should notify the user in the app that it is a paid subscription at the point of activation. I could not locate any notification in the app or on acrobits Softphone website- did I miss it? Also what’s the relationship with Facebook there?

Its very good VOIP app. Its one of best app for voip. I recommend.

Works well with 2 voip lines. I've only had it for a few months I'm impressed with the push notification with 2 active voip numbers Good on wifi &. 3G

Best SIP client for iPhone. Reliable with a nice UI.

Extremely bad sound quality even with the purchased G.729 feature. When making SIP calls, the quality of sound is so atrocious that it is impossible to make out what the other party is saying. This is an issue for both the calling party and the called party. I'm finding Fring to be far superior in sound quality.

Superb!. This is a wonderful app. Use it regularly at home through home Wifi, the sound quality is superior than desktop VoIP/phone unit. That says a lot. well worth the price.

Happy!. Versatile, allow to subscribe with multiple voip providers, well integrated with iPhone network and audio elements, reliable. Well done!

Getting better all the time. I still find this app the one I go back to after trying others. Calls work every time, app stays dormant in background and wakes when someone calls. Yes it does drain the battery if it's set to keep active all the time, but I bought a car charger and keep charging as much as possible and all fine. We now use the app as our home phone (iinet NDSL) on an old iPhone 3G.

iPhone 4. The latest update keeps draining my battery even the app is closed and the phone is standby. U have kill it in the app switcher otherwise u will see in the setting/general/usage that ur standby time is the same as used time even u put ur phone standby. Hope it is fixed soon.

Way better than whats out there. I will keep it short and simple by saying that this software is all you need. My voip provider wasnt in the preconfigured list by Acrobits, but as I am techinical I knew the fact that this softphone should be able to work with any voip provider(PENNYTEL in my case) as long as you have a domain. I popped in all the details and it was all ready to rock and roll. It took me a while to get used to software and all the options it had, but after 10 mins I was good to go. In addition my bluetooth headset works quite well with it and ofcourse the call connects quite quickly. I guess its worth the heafty price tag next to it. These guys have done a bit of work :)

Great App But..... Contacted support as app drops out every 60 seconds. No reply from support so giving it a 2 star rating. I have tested on separate broadband connections and configurations. Same problem.

Noisy & Breaking up. I have connected two voip providers to this app and both have the same problem. Noisy voice breaking up and cracking, re-tested over my computer and voip calls are perfect. If you are serious about making voip calls with your iPhone this app will just cause you too many head aches. I have a very fast WiFi connection and still sound quality is very poor. App needs a serious update to be able to make decent voip calls from the iPhone.

Great app. Very handy app. Supports more than one sip account. Very easy to use. Could you please add the option of turning off those beeps when you record a conversation, it can get a little distracting when taking notes.

Was working. Now not. This app was really good. Was working for a couple of weeks then today, all of a sudden I have no audio when making calls, and the app no longer receives calls. Not happy at this point. Have deleted and reinstalled. Same result.

Great App. Best softphone I have ever used. With the push incoming call which works for any SIP provider it's becoming a super softphone . Money well spent!! Great work 10/10 product The only thing missing is the ability to send SMS from it. Some voip provider support SMS as well. Like pennytel

I cannot use this app. I trefund pl

this is piece of ****,useless.. i want my money back, i am using Bria and you don't want to even compare it to this useless program, you can not call it a Voip software when it doesn't do what it says, not related to it, please give me my money back.

Great app V3. Using with engin byo

Nice app - but...... Works great. However if upgrading from previous version ensure you erase the app and all data first, then setup from scratch again - otherwise it fails to SMS properly (via pennytel anyway).

The application has great potential but currently it is still a beta quality product. I've bought this app in order to be able to record my phone conversations. The configuration process is very far from what an iPhone user is used to, as it requires a lot of technical knowledge to set up properly. I've got this app working with Pennytel and it does what it should - i.e. places calls, records audio, gives access to the recorded conversations over the web. I wasn't so lucky with getting it to work with Voxalot and iiNet - one way audio, calls not getting connected etc. Other apps like Fring work OK with these providers so it's not my network set up which is broken. However, one great thing about Softphone is that it is one of only two apps that I know which do record phone conversations. And it does this job well. The feature I like most is splitting a two-way conversation into right and left channels in the audio file so that one party is in right channel and the other is is left. Great for audio clarity. If you are trying to pull as much quality from your audio as you can for an interview, a podcast etc it is a super-feature that I'm sure no other app has. Things that I'd be really really glad to see improved in the next releases: - user interface: let's face it, the background, as it is now, is unnecessary and creates much visual distraction. the original iphone dialler is pretty neat, so just replicate it! - call voice recording: once again, it's a great feature and a real selling point for this app. audio quality is good. however, accessing and saving the recordings to a computer is a pain. Call records need to be integrated with the native Voice Memos app, possibly tagging the files with the contact name/phone. The audio files needs to sync back to iTunes, like Voice Memos do. Then there would be no more hassles with accessing conversation records over the web, saving them locally, renaming, and putting them into the iTunes. - SIP configuration: needs to be made as intuitive and automatic as possible. also please fix issues with one-way audio - call connect: there's a weird rapid tone at the beginning of each call. very annoying and needs to be removed. All in all, I consider my nine dollars paid as an encouragement for further development. Good effort so far, but if the weak points are addressed it could be stellar application.

Acrobits soft phone and pennytel. Works a treat, very easy to configure.

best voip app. can u update resolution for 6+

Terrific. This is a great app for receiving calls to a landline on your mobile device. Its inbuilt filters are also very handy to block out unwanted calls. Nice job.

bluetooth headset problems. the bloeyooth headset doesnot work well with this app, can't hear well, I have a motorolla bluetooyth that works pefectly fine on local calls. please fix

Love this app. This push notification is working great, saves much battery and speed. The only thing that they need to work more on is that if User can select original ringtones in iphone. Mine doesn't work and the ringtones provided by acrobits are crappy. Anyway, I use my sip phone as my main phone line.

Wow can't believe the sound quality. Set it up in less than 20 minutes. Done calling receiving calls quality is great. Great program.

Excellent programme!. Bravo pour ce programme. Je fais et reçois maintenant tous mes appels avec ce programme et comme fournisseur. 1¢ la minute partout au Canada ou 4.95$/mois illimité!! Adieu les ridicules forfaits de Telus et compagnie. La téléphonie IP sera la mort de la téléphonie traditionnelle!

Failed to received CallerID. As soon as the app goes into the backgrood or the phone lock it stop receiving call. Useless for me. (iPhone 8, iOS 16).

J'aime pas ce programme, surtout apres avoir utilisé skype. pas été capable de rien faire avec ca, c'est asser compliqué, dire que skype tu paie pas pour le programme, celui-ci oui et en plus tu paids le service d'une autre compagnie, pouquoi pas faire ca simple???

Poor Voice Quality. Bought the app for 7.99 Bought the codec 729a for 9.99 Poor Quality on both incoming and outgoing calls.. There is a huge delay for incoming calls thru push notifications... By the time the app is opened and connected.. The other person reaches the voicemail Poor stuff from acrobits

Address book. For some reason I’m can’t not add a personal on this application thank you Robert

Great app turns iPod 4 into an iPhone ( almost ). Love this app as soon as I have a wifi connexion it connects (except one place where it does not work, might be because they don't allow VOIP) When there is no wifi, if I receive a call it will offer me a call back as soon as I connect on wifi Love it (especially that it was 4$ when I got it$

Awesome app!. Great app. The best I've seen. Using this to connect to and it works great. Also purchased the G.729 annex codec and the audio is 100 times better. Hope you guys continue to make this better.

A Sip phone with push that works for a flat price. Exactly what we were looking for, a sip phone that works great, has push function for a great 1 time flat price. Excellent product!

Best sip client!. The only sip client with push support! I also bought the g729 codec and 3G calls are crystal clear. Its not draining my iPad battery down a lot thanks to push. Even if the client is turned off I can still get calls. I have some caller ID issues on my outbound calls... I contacted support, we were unable to resolve this issue, but otherwise they have provided great support. VoIP is not made to be working with nat routers and 3G networks...,so results may vary. Now, I hope I won't have to pay for the iPad version and they will make it universal instead! Buy it now!

Version 4 NOT WORKING with Callcentric. I was looking forward to multitasking support to make this app perfect but on upgrading, I was no longer able to make outgoing calls. In addition the app crashed on several occasions when receiving calls. App crashes when no transport protocol is set under outgoing proxy in advance configuration. I am using Callcentric. Had to delete the app. DO NOT UPDATE TO V4. if using Acrobits have acknowledged and indicate that they are submitting a fix.

Behind competition. I tested Acrobits and Media5-fone against my office's softswitch. Actually, Media5-fone has a higher sound quality. Additionally, Media5-fone supports G.722 and HD voice on Gizmo5 but Acrobits don’t. Try it and you will feel it.

Amazing App!. One of the must have app for my iPhone apps, multiple accounts work so well. It would be nice if we can specify dial plan to use what account for the number. Also it rings only once in the background. Would be nice to get a constant ring. Great app over all!

iPhone 6+ display?. App is awesome! Would be perfect if it was compatible with the iphone 6+ display. Keep it up!

Best soft phone I've tried.. I've been using soft phones for a few years already and this app is the most reliable I have found. Battery usage is good and flexibility in terms of setup is top notch.

Best voip client. Very stable and mature product that is rock solid and has good documentation. To the engineering team, nicely done. It may be time to look at making some improvements to the UI however

Just works. I’ve been using it for years without problem. It uses push notification for incoming calls.

Great, could need a bit of polishing. Works great in general, especially push notification. Would be perfect if the app had a more modern design and better choice of ringtones (they are mostly songs, not very pro). Would love to see that in an update! I recommend it!

works. it works fine.

Problems with the new update. Keeps on disconnecting gizmo and other calls in less than a minute! Push notifications not being received now, tried all options! Previous version was better, can I revert back ?

great app. I use this app all the time . its the one to get because it works ,if you forget to even open the app worth the money all day

Great app. Works perfectly with and Bluetooth! Using for my business so I don’t have to carry two phones. Definitely worth the money.

No sip messaging. Not happy such paid app has no sip messaging

The Perfect Sip Phone. I have already been using one of the pre-configured SIP providers for my home phone. It was extreamly easy to setup. Took about 2 minutes. Now I can take my phone number on the road with me. With this software there's nothing closer than having a cell phone. I do think that the G.729 Annex addin is a bit expensive at almost $10.00 I would pay $1.99 for it in a second. Thanks Acrobits.

Useless. Since switching phone this app isn’t working. I don’t know what is wrong with it. Nowhere a customer service to find. Useless

Spam calls. Since I bought the app, for a less than 24 hours I’ve received 7 spam calls, what I did not receive for 6 years of owning my number. You guys sharing our account details with someone or you have weak security issues on your servers? UPDATE: This app registers your account on cloud server located in New York (USA, ip and someone uses you credentials to make calls. As result you are getting back lot of unwanted calls every day. Looks like someone spying on you. And the company guys says they are not having any servers to register your account... My suggestion is STAY AWAY. THIS IS A PIECE OF JUNK!

Not bad .. Not great. The app mostly works, I do find voice quality can sometimes be lacking even on wifi. Push is ok when it is working, but it isn't always working. Some calls get pushed while others never do, sometimes it will ring immediately while other times it rings after I'm already chatting with the caller on the house phone. So really you cannot rely on push while you're mobile. My guess is their servers can't handle the load.

Excellent softphone. I had this softphone downloaded, installed and working all in the space of about 5 minutes, which is pretty good for me. I was impressed and how easy it was to configure with my VOIP provider, If anything the only suggestion I would make is to have the option to have the softphone as a floating app on the screen. Right now, the only option seems to be to have the app cover the entire screen. It would also be nice to have a link that accesses an online manual to the softphone. Otherwise, a great product. Definitely recommended.

Universal App Please. Why is this app still not a universal app for iPhone and iPad? Will give this app 4 stars when it is made a universal app (NOT separate versions for iPhone and iPad) OK app but the developers are very slow introducing basic features that free or basic apps already support. Responses from support don't seem very knowledgable.

Works great. This app is excellent. I can use this app anywhere in the world, and connect to my home based PBX. I've used this app for a versions now and I can't keep up with all the new features the developers add. This app is never turned off on my iPhone.

very good app over 3G. this app works great it took a bit of work to get it setup with my provider but after it was everything was working great! you would get 5 stars if the dial pad was the same size as the iPhones dialed and if you could delete all in history, it would also be nice if this app could take place of the iPhone dialed rather then closing the program when the gsm option is used

DO NOT BUY. This version constantly crashes. Until they provide an update - save your money. It is not worth it.

Awesome. One star off because I think the UI could be simplified but overall a great product. This is the first VOIP app I’ve ever come across that actually works!

Excellent VoIP Client. I have been using this app for years with no problems. Easy on battery life. Great voice quality.

4 and a half stars. 2 improvements would make this killer app. 1) enable 3way calling. Already available in basic and free apps like whistle phone. This is long overdue. 2) enable multiple google voice accounts. Presently I have to unregister one and reregister another. That's a pain Otherwise excellent. Phone used to crash esp when low battery but new update seems to have solved it.

Great. Everything else is great except push is lag when receive incoming calls.

issues. 1 misleading advertising - cant answer push calls 2 dtmf tones not working can't navigate IVR

DON'T BUY UNLESS UPDATED. The premise is good. The app looks fine but the sound quality is the worse I've seen in any app. Unless they upgrade or change their system entirely, don't bother buying this app bc the receiving end will never be able to understand you!

Great app now.. Since the latest update to 4.9 phone calls have been perfect for both send and receiving over wifi and 3G.

Doesn't wor all the time. I've been using this app for the past year maybe, it had a few flaws such as not running on the background or not always connecting. Now that I've made the mistake of updating it to the newest version just to see what's up it doesn't work! I'm running it on 3.1.3 it connects to my server it let's me make a phone call my the sound doesn't work! Plus if you leave it open for too long it completely cancels all iPhone sounds, such as when u receive a message from ebuddy or even an SMS message and it also cancel any vibration notification Would rate it higher if it wasn't so frustrating to use now because I never know when it's gonna work and when it won't specially because I used to rely on it to make calls to brazil and the us all the time! Not worth whatever they're charging these days specially because you have to pay if you want to use the 729 codec

The best SIP phone out there for Iphone. I have this and a few other sip apps and so far is this is the best. I gave 4 out of 5 stars! only because it didn't have a visual voicemail or a voicemail MWI. Its seems like they forgot it. The push feature for incoming calls work great with no issues really. G.729 codec was extra but hey everyone has to pay the patent holder for this codec And works great on Rogers 3g network with my sip provider ( Please upgrade voicemail features thank you Scott

iOS freezes when this app is launched. Also, UI is not smooth. Slow. Shortcuts are not useful and the UI is horrible.

I never use it.. I bought it to see if it could fit my needs but to no avail. I had trouble registering and when it registered I could not receive calls.

The proper way to VoiP on iOS. I switched to a data only plan serval months ago to get more data for my money and I've got myself a phone number with I've been using the app to make and receive calls and it's been amazing. It's reliable and easy to use. Especially when receiving calls, compared to other apps, it is just like any other gsm call. Very well integrated with the ios voip api Highly recommend

Needs an update badly!. Since this company came out with groundwire they have just ignored development on this app. It has been more than 4 months without an update. There are tons of issues with call quality and it doesn't work well over 3G. When you contact support, they say groundwire will solve all your problems. Basically they don't care about this app and want more of your money.

Excellent. Excellent and only takes a minute to configure with included templates for most SIP (VOIP) providers. Pretty much works right out of the box (so to speak). When travelling anywhere in the world it pays for itself in less than 10 minutes by negating the need to use call-forwarding and call-initiating (on my plan about 20x more expensive than normal SIP calling which this softphone allows for). In fact, my provider actually recommended this particular softphone as from their experience they’ve had the least trouble from it and waaaayyyy less trouble than from the free softphones floating around out there.

Excellent High-Quality VoIP app. Best VoIP phone app by far - Ive tried several and usually none if them work properly, except this one! A nice feature to have would be that we see from which account a call is coming from, in real-time and in the missed calls list and then it would be the perfect app!

Solid, well-designed SIP client. I’ve used this app for several years and am very happy with it. Comprehensive feature set. Can register with multiple voip providers. Works well with It has a clever number rewriting feature to deal with internat numbers prefixed by + in my iOS Contacts.

It stopped working. I have a problem receiving calls. It use to work using the same settings. Now people have to call twice to get me. Next there needs to be an option to use photos from the camera roll and the photo album as the background theme. Next I miss calls if I don't pick up after 3 rings. Please extend it to six.

Pricey, no SMS, lots of settings control. This app is rather pricey for what it does. No SMS. Call forwarding from google voice is buggy. Push notification relies on iPod being awake (true of all voip apps I've tried). But if it techies will like SIP setting controls. Also call recording unique and neat.

Exceptional SIP Phone - A worth every penny!. I have tried many of the iPhone SIP phones. This one is exceptional. It's problem free, it works well. The ability to boost mic and ear volume means no more "too soft" calls, which is a problem with many other SIP phones. This has all the options you would want; they are clearly presented so as to not be confusing, it's just an exceptional product. Other features many SIP phones don't have are: -Digit insertion/suppression capability (rule based) -Boost microphone volume -Boost ear volume -Full Bluetooth support -Multiple VOIP accounts with easy selection between them -Push Notification of incoming calls -Support for many codecs, including licensed codecs (extra cost) -Customizable colors -Displays status clearly and shows which codec is in use.

Awesome SIP app for the iPhone. I would recommend this app for SIP calls. The push function works and it is essential for incoming calls. It supports NAT via STUN. It is worth the money. I have tired other free ones and they just don't work as well and aren't reliable especially for incoming calls.

Almost there. Works well. Biggest issues I have is needing to pay extra for 729 codecb and not able to silence call properly or choose vibrate only. Would get 5 stars other than that. Will make my decision by next week if I will keep or pay for another well rated app that includes 729 for less than the "add-on" cost

Almost good.. If you don't buy the 729 codec, don't thinking about using this on 3G. Also call quality is not very good, I always have people telling me that I'm breaking up, plus you can't modify the ringtones on the push notification account and control the ring loudness. Stock ringtones are horrible and way too loud. Good concept that needs some rough edges smoothed out.

No push support.. This app supports only gizmo5 for push. That means, if you have different sip provider you won't be able to receive calls when the app is closed. Sad thing is that gizmo5 suspended new member sign up. Other than this, the app works great!

The best. This app does everything you need. I love it. I like the ability to do the advanced settings and different account integrations.

Sound quality is good, price is too high and PUSH notifications do not work.. So far I use this client for outgoing calls... but I also have iSIP installed and there the PUSH notifications does work ...but not in this app. Get that working, the incoming call log and a small number indicating how many mist calls you have, and you are fine. The bluetooth is really bad in this app. The app is on the right track.

Best sip app I used. I tried other apps, and I was looking for something easy to use that I could setup with my asterisk server and that would support my Bluetooth headset. This app fit the bill perfectly - even better now that AT&T allows sip over 3g!

Need improvement. Out of many soft phon I used so far this one is worst. Issues Calling back a number not works if I am trying to call back from my missed call. I need to call dial to get connected . In case clicking from missed call error will be displayed Audio not going to Bluetooth device. Inconvenient while driving No option for Poor coverage area. Vonage soft phone has option to get connected on your cell phone by incoming call

Best sip phone I've tried. I've tried so many sip softphones and this one is the best by far. I use mine with Asterisk on my LAN and it works great. The cheaper and free sip phones I tried didn't compare. My only request is to allow the ringer to be customized or allow silent mode when the switch is set to silent.

Nice, but not for incoming calls. It's a quality app that's pretty easy to set up and use, and the voice quality is great. It also has the nice feature of being push compatible so you should be able to receive calls when the app isn't in the front-but when in the background, the call always expires before I can answer it. Fix that and you have a real sip phone!

Quality is great fixed gizmo5. Turns out I had a gizmo5 issue. And customer service helped me through it. Made call on 3G using the g729 add on. Thought I was on my regular phone. Superb quality :)

Outstanding. I also have tried several other SIP Apps, and found this to be the best I've tried. It interacts great with IPHONE Contacts, has good audio quality, and runs very smoothly. I use this with Broadvoice and tried to use it with vonage, but had trouble with Distorted Audio.. One of the only drawbacks with this and any other app for SIP use, is that the SIP Providers wont really assist you to resolve problems if it's not one of their sanctioned devices. Broadvoice, has been very helpful with answering questions, but not so much with Vonage.. I highly recomend this app... Kenny

Great app. I use the app for outbounds calls. I had a problem with call quality, I sent an email to the support and got an answer in the same hour. I Also installed it to my mom and she manage to use it and save $$$$ in her last trip. The design is not amazing but it's working. Pls add ios4 support.

Solid VOIP. I've tried several SIP clients on the iPhone and Acrobits is by far the best I've used. Every feature listed in the description works flawlessly. There are a features I really miss but I'm happy to find a reliable application. The best $8 I've spent.

Great App, Responsive Support. This app works as advertised. Sound quality great on WiFi and iffy on 3G. Setup is easy. The interface is elegant an iPhone like. I wanted to hook it in to my Asterisk PBX server and ran into some server side troubles. The folks at Acrobits were responsive and helpful.

Not quite ready for primetime. Decent app, but certainly not ready for business use. No transfer or conference capability which renders it useless in a business environment. A "business" version is coming according to Acrobits support, but that will cost more and there is no upgrade path. Thus, I'm pretty disappointed that I spent $7.99 on software I can't really use. Who makes a softphone application that doesn't have a transfer or conference feature? On the positive side, it registered easily with my IP PBX (ShoreTel) so I was quickly able to make my one call.

Can't trust mute!. I've been using this sofware for almost a year, with few non-DTMF problems. Today, I was running it on my iPad with the screen locked on a call. I unlocked the screen and checked that the mute, and it was on. However, it wasn't actually muting the sound!

4 stars cauz. This app is good, stable, easy to setup. Push works great wifi or 3g. Calls over 3g work great when all the cell service bars are on. Not 5 star cauz bit pricey, no transfer and does not display contact name on caller id.

Works fine in my iPod Touch. I use: - 64GB Ipod Touch - The same earphones and mic that came in my iPod Touch - Generic SIP user When I am on the road, I used to talk with a Soft-phone Software installed in my laptop. But with this app in my iPod Touch I don't need to Start my MacBook to talk. You can use your Address Book contacts in your iPod, you don't have to import nothing. The configuration is easy as a Generic SIP account user It works for me.

Excellent app!!. Call quality is very good both over wifi and 3G. But over Edge is pretty good too, with a little in-app upgrade. Runs smoothly on iPhone4, 3GS, iPad, and iPad2. By the way, it would be very nice if they make a universal app for this or another one native on iPad :-)

Great app. This app works great for me. Works very well with google voice and sipgate. I was not as impressed by the gizmo5 call quality. It did take some configuration on the router to support alg and to open the required ports. Once the setup was complete the sound quality is excellent.

IOS 4.0 Not quite. I like this app but push and background only sort of works. If the app is up double click to switch to another app and then come back to this app, but I can't have in the background like say Pandora or MapQuest and then be back on my home screen which is what would be perfect. Stil some work to do but getting closer. It will go to 5 stars as soon as backgrounding is fixed.

Excellent Quality. Using this with Unovon, amazing quality, connects to Bluetooth in my car so quickly. I am saving so many anytime minutes on my account. Great purchase

Integration into iOS 10 makes this a winner. I don't usually leave reviews, but it is SO WORTHWHILE to be upgraded to iOS 10 and using this app. The ability for this Softphone to integrate into the lock screen for call pick ups and the regular iOS Phone app is phenomenal!

Push notification doesn't always work. It will only work immediately after I close the app. Once I go into at least two other apps, or lock my phone, push notification doesn't work. UPDATE : Upgraded to new version for backgrounding. App is VERY buggy. Crashes, ringtones play at fast speed or slow speeds.

Best VoIP. i have tried them all and this is by far the most feature rich of all.. excellent tech support... works flawlessly on iPhone 4/iOS 4.1 in the background with multitasking !

A must. Very fast from app launch to calling. A must have for anyone with an iphone and poor cellular coverage. As long as you have wifi, you can make calls - even on iphones that didn't get wifi calling in iOS 8 such as the iPhone 5. You just need to pair it with a voip service.

Smooth transition. I already had a setup with PBxes for my droid making the adjustment for this client was as easy as cut and paste. Works well with my itouch. Used with google voice and you got your self a phone.

best so far. excellent call quality and stability. inclusion of iLBC is the real selling point for me as this codec manages to maintain good call quality under imperfect connections. tech support is also excellent. easily configured for providers that are not listed out of the box (rapidvox in my case). doesn't make 5 stars as push will only work if you have been good and not tampered with your phone, although this is a limitation that is probably not Acrobits' fault. Today Apple officially lets us use voip over 3g, please give us a suitable update soonest! Suggestions: codec priority should depend on the connection (wifi/3g); bigger dial buttons; choice of skins and ringtones

Great softphone, great support. Very pleased with app. Was worried about the .cz domain... but no problems - works very well. They responded very quickly to some questions I had. They also have some video tutorials on their web site which are professionally done and quite useful (even for someone who thinks he knows a lot about VoIP!)

Simply great!!!. Really easy to configure. The only thing missing is ability to place calls through 3g. Keep it up. I love this app and I personally use it a lot

Great App!!!. Been using it for a couple of months now. I've used a 3G and a 3GS. Easy setup, great quality. I would have given it 5 stars but like others I feel it's a bit pricey and it needs transfering. Fring is free and has pretty good quality. The Gizmo5 app was made by Acrobits and only costs 1.99!!!

Works with asterisk. Works with our Pbxiaf Asterisk system from inside our office and outside. Good voice quality when I am on a decent network and wifi signal. Sure saves on LD when visiting strange countries.

Awesome AWESOME Awesome. This is the most AWESOME APP EVR!!!!! Here r some sugestions. Make it so when u miss a call it shows up in history U should make it so when ur not in the app even if u hav the headphones in it uses the speaker for the push notifications When u answere a call or make a call on an iPod touch make it so u don't hav to hav the mic in. But when u plug in the mic the other person hears u. Also make it so u can put ur own ringtone!!! If u make those changes it would be even AWESOMER!!!

Best SIP Softphone. This is without a doubt the best SIP softphone for the iPhone. It is very versatile. You can configure any standard SIP account. Even an Asterisk server works great. Now it supports calls over 3G which work remarkably well (tried it on ATT). The only thing on my wishlist would be G729 support.

Works great with Gizmo5 and Google Voice. Get incoming calls from Google Voice with push notifications. App loads a little slow but other than that it's the best SIP phone app in the app store.

You have a great app. Works well. Not sure what's going on with the google voice option. Instructions? Hope it will work with gv soon.

Not worth it, Bria is better. I had problems from day 1. Wifi on a 30mbps connection or 3G the other party complained about the call quality and breakups. It also could not make calls with some providers like future nine. I've tweaked settings and everything. I have a pap2t and asterisk as well and they have no problems at all. I lost my money :(

Geat APP for VOIP. I ran into some issues with earlier versions but the latest version has been flawless. I've tried others, even on other phones like the Droid and this app really is the most comprehensive and easiest to use voip app I've seen. You won't be disappointed.

Works!. Push actually worka with this app. With a 3G unit, I can lock my iPad and still get calls and actually answer them, unlike with iSip which hangs up after I answer a push notification. Only thing is you have to get a stun server. Why don't they provide one?

SMS support. The app has a google voice interface which is nice. What would really make it shine would be to allow text messaging and show your google voice inbox - transcribed voicemail and text messages. After all, not everyone's running this on an iPhone.

The future is here. Using acrobits with iPhone 4s and teltub. It works flawless for me on a good wifi connection. Time to do some real world testing to see if it's time to ditch my cell service.

Inbound Gizmo5 calls no longer work. This app works great. Sound quality is good and push notification is quite reliable. While I had some issues with its integration with Gizmo5 for a while, their technically support was eventually able to fix it and release a new version. Kingsbury

New ios4 version crashing. I just bought this app because they release the iOS4 version that multitasks, but it seems to crash quite easily and is not very reliable. I really needed something that was reliable to use with my PBX and am disappointed, especially at the price they charged. Hopefully they will release an update that fixes the bugs quickly.

FANTASTIC APP!. For anyone travelling this is a must have. It will save you lots of money. Nice interface and great useability. Works when the app is not running and uses the address book seamlessly - try it!

Background battery usage high. With the may 17 update the app is heating up the phone and burning the battery down quickly while in the background. Apples battery usage tool shows this is the culprit. I ran a year or so old version before this and didn't have any battery issues with the same voip provider and phone hardware (6s+). An extra star because this no longer is pre-emptied by regular LTE phone calls.

Best on iOS.. There are other decent SIP softphones, and lots of free ones, but I am very pleased with the features and configurability of Acrobits. The G729 codec is worth the money too, since the internet here in rural Thailand is rather slow.
