    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 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.

    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

    ******* 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.

    Good app. I like the channel separation (stereo) call recording, but was unable to set up secure calling with push. Some settings are very tricky to understand and in-app help is barely understandable, partly due to poor translation into English.

    An very good app that would be perfect if touch tones worked "faster". There seems to be quite a lag from the time a number is pressed till it registers with the remote PBX. Tech support is top notch, very helpful.

    Fantastic integration with the native Android dialer. This is the ONLY sip app that fully integrates with the NATIVE android dialer for seamless call handling. Keep up the good work!

    Bought to test, as there is no trial. Refund was rejected. Support won't respond to my ticket to resolve this. 0/10

    Groundwire Push notification not working in IRAN, seems groundwire push servers IP blocked by government! Plz find a solution, for example add http or socks proxy option in groundwire like Telegram app has done.

    Great application, the only one, correctly working with PUSH backed incoming calls . Feature request: web hook ( web service in your app ) like rate and balance checker for incoming call number lookup. So one can intergate your app with some remote service for spam call checks or remote contacts database.
