About this app

Sheerbit Softphone is a SIP, VoIP and WebRTC softphone for Android: a professional mobile dialer that turns your phone into a business phone, SIP client and IP phone. Connect it to any SIP server, PBX or hosted VoIP platform and start calling, with reliable background calling so you never miss an incoming call.

No subscription. No per-seat licence. Add your SIP account and you are ready to talk.
