Now my mobile plan costs me only 2 bucks (my voip provider price) and it works anywhere in the world where internet connection is available. Thank you!

I don't know when it got added, but I was very pleased to see the system dialer integration. I know it is currently experimental, but it works well. On older versions of Android, I used to use the dialer app to add sip accounts. Once they got rid of that in Android, I began using Ground wire. It worked well, but up until the system dialer integration feature, it was a little lacking and how it interacted with Bluetooth devices. So, I appreciate this feature, and I hope that it stays!

I purchased this app and use it with VoIP.ms service. I can't receive calls. The PUSH notification pops up, and it then rejects the call right away. Zoiper free version works out of the box. I purchased this app because of the PUSH notification feature. Also switching to standard non PUSH doesn't work for me either. Please help to get my incoming call to work or provide a refund.

Broken in the latest version and was running previously. Can't answer the calls, and it continues ringing even after answered on another device. Have to force close the app to stop the ringing as it doesn't respond to Answer or Decline.

Groundwire does not work with my custom vpn: it fails to connect to the internet. I have a rooted phone, and has a custom tun-to-socks tun interface set up with "ip rule/ip route". I then use another socks proxy to connect. The problem is, when I direct traffic of ground wire to that tun interface, ground wire fails to send/receive network traffic. No other app has the same problem, and ground wire version <= 6.4.33 worked as well. But newer/latest versions of ground wire do not work.
