About Baresip

Baresip is a SIP softphone built from modules, handling voice and video calls with unlimited accounts and calls, call transfer, hold, recording, conferencing, instant messaging and an address book with presence. Calls can be encrypted with TLS signalling and SRTP using DTLS-SRTP, ZRTP or SDES key exchange.

The audio pipeline offers low latency, echo control, gain control, noise reduction and many codecs. It suits people comfortable configuring a text-based SIP client, including embedded and headless setups.

  • Encrypted calls with SRTP and ZRTP
  • Unlimited SIP accounts and calls
  • Wide codec support and echo cancellation
  • Modular design for custom builds

Limitations

  • No graphical interface in the core program
  • Configuration takes some SIP knowledge
