Background and context SIP (Session Initiation Protocol) is the de facto signaling protocol for initiating, modifying, and terminating multimedia sessions such as VoIP calls. SIP clients (softphones) handle user registration with SIP servers (registrars/proxies), call setup (INVITE/200 OK/ACK), call teardown (BYE), and in-call control (re-INVITE, NOTIFY, INFO). Media (audio/video) is delivered via RTP/RTCP, with codecs negotiated using SDP (Session Description Protocol). MicroSIP implements these SIP fundamentals while prioritizing small footprint, minimal dependencies, and adherence to common SIP features (registration, multiple accounts, codecs, NAT traversal via STUN/ICE in supported variants, DTMF methods, etc.).
