# Changelog
## 2026-04-10 - 1.13.0 - feat(proxy-engine,webrtc)
add B2BUA SIP leg handling and WebRTC call bridging for outbound calls
- introduce a new SipLeg module to manage outbound provider dialogs, including INVITE lifecycle, digest auth retries, ACK handling, media endpoint tracking, and termination
- store outbound dashboard calls as B2BUA calls in the call manager and emit provider media details on call_answered for bridge setup
- separate SIP and WebRTC engine locking to avoid contention and deadlocks while linking sessions to call RTP sockets
- add bidirectional RTP bridging between provider SIP media and browser WebRTC audio using the allocated RTP socket
- wire browser webrtc-accept events in the frontend and sipproxy so session-to-call linking can occur when media and acceptance arrive in either order
## 2026-04-10 - 1.12.0 - feat(proxy-engine)
add Rust-based outbound calling, WebRTC bridging, and voicemail handling
