Comments on Groundwire: VoIP SIP Softphone for Android

★★★★☆ Michael Kelly · Oct 16, 2025

The app is good. Recently however, something changed either on my provider end or on ground wire that has prevented it from successfully taking and keeping call center calls. It seems the req comes into Ground wire's TURN server but even when set to TURN only the ack is coming from STUN and the call drops once the request to TURN times out. I tried multiple other sip clients and did not experience this issue, I can send more diagnostic info to an email if there is one for support.

★★★★★ Matt Faraday · Jul 25, 2024

Works perfectly for me. I've tried a handful of VoIP apps and this one is the most consistent and works well. I like the push notifications. I like the features, the interface etc. The only thing I'd like to see is the ability to block callers, that's the only thing I think is missing. I'm using it with two different VoIP providers, and it's been flawless the entire time. The only time I've had an issue it was more to do with my underlying connection than this software.

★★★★★ JOEL (Joel Dominic D Almeida) · Jul 24, 2025

One of the best VoIP soft phones that I have used on Android and only one limitation is no qr code based account configuration if they could add that then it would be really awesome.

★☆☆☆☆ YM M · Aug 30, 2025

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.

★☆☆☆☆ Matthew Austin · Mar 16, 2026

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.
