This is a bare-bones Android Studio project implementing baresip based SIP User Agent.

Currently the application supports voice calling and messaging, UDP, TCP, TLS, and WSS signaling transports, voicemail Message Waiting Indication, incoming call transfers (REFER), PCMU/PCMA, G.722, G.722.1, G.726, G.729, AMR, and Opus voice codecs, as well as ZRTP and (DTLS) SRTP media encapsulation.

Motivated by need for a secure SIP user agent for Android that does not depend on third party push notification services.

If you need video calling and have a device with Android version 7.0 or newer that supports Camera2 API at LEVEL3, you can instead of this application install its sister application baresip+ from video branch.

After cloning the project, generate static libraries and include files to distribution directory using master branch of libbaresip-android.

Then in Android Studio Arctic Fox 2020.3.1:

  • Open an existing Android Studio project

  • File -> Invalidate Caches / Restart -> Invalidate & Restart

Available also on F-Droid and Google Play.
