reSIProcate is a set of C++ libraries and applications for building SIP endpoints, proxies and media servers. Source code, issues and the wiki are at https://github.com/resiprocate/resiprocate.

Libraries

rutil: utility classes used by everything else, including resip::Data, logging and the DNS resolver.
resip: the RFC 3261 SIP stack (resip::SipStack). It parses and builds SIP messages and handles transactions, transports and RFC 3263 DNS lookups.
dum: the Dialog Usage Manager (resip::DialogUsageManager), a higher-level API above the stack for building SIP user agents and servers (no media).
recon: a SIP user agent library with media support above dum (recon::ConversationManager, recon::UserAgent).
reflow: media flows for recon, with STUN, TURN, SRTP and DTLS-SRTP (flowmanager::FlowManager).
resipmedia: SDP and RTP port helpers shared by recon's media stacks.
reTurn client: a STUN/TURN client library (reTurn::TurnAsyncSocket).

Applications

repro: a SIP proxy, registrar and presence server (repro::Proxy, repro::ReproRunner).
reTurn server: a STUN/TURN server.

Grouped Classes

The SIP stack tags its most important classes with these groups:
