Get baresip+ old version APK for Android
VoIP and mobile calling and messaging app based on baresip SIP library
Currently baresip+ supports SIP and mobile based voice calls and messages as well as SIP based video calls. In addition, voice conference calls, voicemail Message Waiting Indication as well as blind and attended call transfers are available when SIP is used. MMS messaging is not supported yet.
In SIP calls audio can be coded with Opus, AMR, Codec2, G.729, G.722, G.722.1, or PCMU/PCMA codecs. Video can be coded with VP9, VP8, H.265, H.264, or AV1 codecs. Security is achieved via TLS or WSS SIP signaling transport and ZRTP or (DTLS) SRTP media encapsulation.
Development of baresip+ is motivated by need for a secure, open source SIP based VoIP User Agent for Android that does not depend on proprietary, third party push notification services. Mobile calling and messaging was added in order to reduce app pollution.
This application can be installed on Android devices running Android version 9 or later. Mobile calling and messaging needs Android version 10 or later.
If you don't need video calling, you can instead of this app install its lighter weight sister app baresip.
Source code is available at GitHub, where also issues can be reported.
