Its development is motivated by need for a secure, privacy focused User Agent that does not depend on third party push notification services. Currently baresip supports SIP and mobile voice calls and messages. 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. Security is achieved via TLS or WSS SIP signaling transport and ZRTP or (DTLS) SRTP media encapsulation. -This application can be installed on Android devices running Android version 9 or later.

Mobile calling and messaging requires Android version 10 or later. If you need video calling and have a device that supports Camera2 API, you can instead of this application install its sister application baresip+ from the video branch.
