App ChangeLog

  • Bugfix in audio handling: receiving an incoming GSM call during an ongoing SIP call or switching calls in a conference could have caused loss of audio for the SIP call.

    hi there. I love that I can finally receive calls. But at the moment incoming calls are not recognised with the phone book. In my phonebook the numbers are with country code.. +45 (for Denmark) The incoming calls do not have country code, if they come from Denmark. What should I do?

    groundwire ministry ******* DO NO PURCHASE THIS APP ******* As soon as I open this app I cannot receive calls via cell and they are sent immediately to VM, even after exiting and force closing Groundwire. I must reboot my device to receive cell calls again! (Galaxy Note 8) Please fix this as Groundwire is useless in it's current state! Update: devs are unresponsive. I've uninstalled and moved on to a mire reliable SIP app.

    groundwire coffee Doesn't answer incoming calls - connected to Sipgate on Galaxy S4 and test for push notifications passed but no dice. Also showed SSL cert expired and couldn't connect to provider list. Shoddy! After a lot of googling I conclude incoming voip calls are never going to be reliable enough on mobiles and battery life will always suffer so this and similar apps are basically worthless.

    troll team I have been using this app for sip VoIP phone and it has been great so far. It has a few issues with bluetooth selection from time to time. Especially when multiple BT audio devices are active. Cannot choose which BT device to use. And sometimes the BT device shows connected, but the speaker icon in Groundwire won't show the BT audio in the selection choice. I sometimes have to end the call, turn off and on the BT device, and remake the call for it to work again.

    Tried so many others including Bria, Zoiper and a few more and none of them worked as well as Groundwire. Love the native dialer support and also the app actually looks like it was designed for today and not the 2000s like others mentioned.

  13. Alex Gaudet-avatar

    Alex Gaudet


    It is impossible to close the screen while talking. It will turn itself on. So if you speak phone while walking with headset, chances are you will accidentally hang up. Very stupid behavior. Also, the recording option makes a beep continuously so you can't record any conversation without being caught. Again, silly behavior. Don't by this app.

  14. Rob Riccardelli-avatar

    Rob Riccardelli


    I have tried nearly every SIP application for Android, both free and paid. By far, this is the most reliable and least impactful on your phone's battery life. With this app, I never worry about missing incoming VoIP calls anymore. It even works well over cellular connections. If you conduct business on your Android device, this app is money well spent.

  15. Kevin Roland-avatar

    Best softphone that I've used to date. The features that I have found most valuable are the custom dial actions and number rewriting. My outgoing providers have different requirements when it comes to number of digits and prepending numbers for domestic calls. And, my address book is a mixture of 10 and 11 digit numbers. With number rewrite and custom dial actions I just have to select the contact and the app does the rest, depending on which provider I select.

    It works but it's not very user friendly. I can't even change the ringtone to differentiate between calls. It's stuck on call integration mode and u can't figure out how to change it. Every call looks like it's coming through my provider now. I'm revising my review. After reinstalling I was able to reset the call settings that were locked during the initial install.

    I used to love the app, but recently at times after using the app my phone still thinks I'm in middle of a call even after closing the app, therefore the phone won't ring and when I try to leave a VN in WhatsApp it tells me I can't record a VN during a call, even though there is no active call, it's just that Hroundwire didn't update the OS that the call has been hung up

    probably one of the best voip apps that I tried and I tried a dozen, I like the features, myriad of settings,, integration with system caller., automation, do not disturb plan etc. however there is one quite serious bug that I am experiencing. puts the incoming calls on hold randomly without any input from the user. sometimes works for a minute, sometimes the call goes on hold every 5 seconds, sometimes it works for the duration of a whole call even 3 minutes. outgoing calls seem to be working well. what buggs me is the fact that I do not get any feedback that the call was even put on hold, Im just here, talking to myself... I thought it was because I used battery saver, but that wasnt it and nothing is blocking the app from running in the background either.

    used to work perfectly, but suddenly, i lost the ability to make all outing calls. I'm not sure what is the problem, tried troubleshooting w their website, delete any number rewriting, no caller ID on the custom girls, outgoing calls enabled, etc... sad, and i paid money for an app that doesn't work.

    Thanks for the prompt support Gabriel , highly Appreciate your Assistance, The app is over all nice and neatly made, how ever my operator has issues with the Push as a result i was not able to use it to its full potential. I would recommend people to purchase the SIP app if your operator supports Push notifications.

    I was very happy with the app but lately after I hang up on a VoIP call my Galaxy 8 thinks im still in the call and my calls dont ring on the regular phone app and when I try to leave a voicenote in whatsapp it tells me i cant record voicenotes during a call, only a reboot helps, when this will be fixed i'll change my rating.

I would like to see the UI updated to a material design to give it a modern looks and support Wear OS for notifications of incoming calls.

    Excellent app. The best among 20 softphones tested in a period of 6 years, although on the expensive side. Push notifications work perfectly on both iOS and Android. By far the best Bluetooth support around. Highly customizable with nice new interface and better settings. However latest update makes it impossible to switch off vibration on ringing even when general setting is off on android 6.0.1. On android 7.0 I had to set vibration intensity to zero in order to get around this problem. Also when the app is open and phone screen rotates to landscape in any other app eg youtube, groundwire starts dialling last number. Very annoying indeed!!!! Bugs that need to be fixed. Still gets 5 stars easily.

    Worked for one week only... Now it hangs on open and never responds on a Pixel 2. Resetting handset does not help, this is now useless. While it worked, I fielded exactly two calls from a gradwell VoIP service in the UK from the US. Too bad.

    Overall good VoIP application. Lots of options, and quite reliable in my limited testing so far. My only complaint is that it doesn't have the account-specific DND option that its iOS counterpart has. Due to the lack of feature parity in that respect, I've knocked one star off. Would be happy to change if that feature is added.

    It used to be an excellent app, now it's useless. When I receive a phone call, the answering screen appears and freezes, accepting no feedback. I can't even reject the phone call or kill the app. On an A5 2017, so not exactly an old phone. Terrible user experience: DEVELOPERS TEST YOUR APPS PROPERLY BEFORE COMMITTING UPDATES. This is ridiculous.

    this recent update has a little problem... when the phone rings while using any other apps, a small notification comes out from the top, but the notification box does not show the callerid.... it only indicates that there is an incoming call.... otherwise, this app has been a very reliable and battery saving voip client. keep it up

    Been using this app for a few months, back before the interface upgrade. It was actually running fine before then. Ever since the upgrade, its horrible; it can't stay registered through network switches, people can't hear me well and audio issues galore, big battery usage and reduced Bluetooth functionality. I've sent in bug reports, and the developers respond, but the issues just keep reappearing. This used to be a good app, now it's just like all the other (free) ones.

    After to many hours trying and reviewing all the major sip apps, i've found this to be my 2nd equal sip phone app, Test phone is a Zenfone 3 running Android 7. Two accounts registered, used in a small business environment, interface is one of the best, good call quality, reliable but in priority order if it wants t be the best. 1] ringtone is timing out, i think it's not looping back to the start of tone 2] be able to switch off missed call notification. Now what i have found that makes this app work on the Zenfone 3, switch off battery optimization in settings for this app makes it reliable, even when using push. to switch off the video function on the call screen, move all the video codecs into disabled, to get the proximity sensor to work, check remember audio route in sound settings, and on the dialer screen when making a call choose receiver by pressing on the speaker image on the left side, no matter what app you use, make sure your codecs match you provider / pbx, this makes a huge difference to call quality, review updated 9/5/17

    Does not offer a intuitive way to look up a contact, unlike my phone's default phone app and many free SIP apps. Does not integrate with the phone's normal phone functionality, like 3CX for example.

    The best app period. Gr8 job! Especially the push notifications. Dont understand why I cant chose my own ringtone & theme. Seems pretty standard on other apps. But its cool. This app rocks! Request: Since there is push notifications, can there be an option to close the app after a call. Don't really need it to stay open. Wish it could also switch from Wi-Fi to Lte without disconnecting and vice versa.

    The push notifications work well and this is the make-or-break feature of this particular softphone client. I'd be giving it a five star rating if SIP handover was implemented, like other products on the App Store - such as Grandstream Wave. For now, when moving between Wifi and mobile data networks, ongoing SIP calls are dropped. This handover mobility is the one missing feature that would make this a truly brilliant mobile SIP client.

    Works well on Samsung Galaxy Note II, Sony Xperia LT26i, Samsung Galaxy SIII, Samsung Galaxy Note 10.1, Sony Xperia Z1, but crashes on Samsung Galaxy SII Plus. As a notice to developers: in previous versions it was more comfortable to see if app fails to connect to SIP server (I mean green and red icons in Android status bar). It looks nice, but not clear to understand instantly if there is any problem. I think implementing option to switch between old-style and new-style icons would be great.

    The phone works very well, as advertised. However even though it is not running it causes a error every time I use my mobile phone to make a call. Unfortunately once I'm connected on my mobile I cannot hangup or do anything else on my phone until I clear the error.

    A new update yet still the same old lousy design.. This app used to be the best in SIP communication, now not so good. One of the simple things that needs to be updated is the menu key on 4.3 and above which I've emailed then about long time ago. And the design is very old which should be updated. Call quality isn't as good as I used before. Finally there should be away that I get the app which I paid for on play store for free on amazon store since they're both Android?

    Really time for a Material Design refresh to the interface. Menu key and sometimes cryptic methods of performing actions, like deleting a SIP account, should be revised. As should last image showing version number in Play Store. Also, the ability to disable the confirmation exit dialog box via one time checkbox should exist, especially for those who have push notifications enabled. From a functionality perspective, this is though the best SIP client out there.

    Groundwire nearly bricked a Google Nexus 7 and clobbered other apps that worked great before. We thought that Counterpath's Bria SIP soft phone was poorly designed until we worked on configuring several SIP accounts in the Groundwire app. There are too many different screens with settings squirreled away to get just one account working, and no diagnostics to find out why additional accounts will not register. Since this app is more expensive AND so much more difficult to use, AVOID it. I want a refund.

    I'm a new user of Groundwire. I have it installed on a Galaxy S4 Mini, using Push Notifications. I'm using a Jabra Bluetooth headset. Now, when a call comes in, it doesn't ring on the headset. Similarly, if I hear the ring when the phone is in my pocket, I can't pick it up using the headset button. I have to open the phone and tap Accept. That's no use if I'm driving.

    I have to say I've tried a lot of the SIP phones in market and I was a little hesitant... well... a lot hesitant to try this one because of the reviews & price. I think it has more features and is better suited on Apple's iOS than Android. But I gotta admit I was surprised. The one issue that stopped me from using a great open source softphone like Csipsimple was the deep sleep thing that occurs with Android phones. Every time my phone went into deep sleep with CSS I missed incoming calls. So I decid

    This is the best voip application that I ever used. I have heavily used VOIP for a few years and this app is the best available. The support team helped me very quickly to solve a bug. I have been able to use the recording features, conference call and call forward. This is rock solid. I can manage my 2 VOIP lines from 2 countries in one place, and even make a conference call with people from two countries to another using my 2 lines, all within my phone.

    The latest version crashes when making a GSM call. Still no easy way to disable. Turning of push notifications does not stop incoming calls, have to uninstall to stop working.

    Decided to check back on the app which I've bought in the beginning of 2014 and submit a review. As I don't use ZRTP nor G.729, for me the biggest feature of Groundwire or a smaller sibling from Acrobits -- Softphone was the push notification. It works very well if you're not concerned about sending your SIP credentials to a small company in Czech Republic. Ultimately tho, the push notifications support hasn't swayed me to switch away from the old and trusted SipDroid. Yes, push notifications save battery, but even without them my phone usually lasts thru the day and I charge it at night anyways. What made me go back tho was the lack of the stock dialer integration and any kind of rules to direct outgoing calls to either mobile operator or SIP client. It is especially annoying as sometimes I make SIP calls while on the road and there's no way to do it handsfee with Groundwire. Thru the year I've participated in the beta program and installed a few of Groundwire beta builds which still didn't provide good integration with the stock dialer. Unfortunately, about 9 months since the last release there's no update. :(
