history
Project history and usage
PJPROJECT is a portable C multimedia-communications project implementing SIP signaling, audio and video media, RTP, SDP, STUN, TURN, and ICE, with both low-level libraries and high-level user-agent APIs.
Project history
PJSIP development began before its first public release, which appeared in February 2005 as version 0.2. Even that small early release could establish a voice call and ran on Windows and Linux.
The project subsequently developed a layered architecture covering SIP, SDP, RTP, media, STUN, TURN, and ICE. High-level PJSUA-LIB and PJSUA2 APIs made the lower-level components more accessible to application developers, while mobile support incorporated native multimedia facilities.
Adoption history
PJSIP has been developed by a dedicated team since 2005, with contributions from hundreds of developers. The project reports routine testing at SIP interoperability events since 2007 and supports desktop, embedded, and mobile environments.
Its layered C and C++ APIs have been adopted in softphones, embedded communication devices, mobile applications, SIP testing tools, and products needing a portable signaling, media, and NAT-traversal stack.
How it is used
Developers embed PJPROJECT libraries in SIP and real-time communication applications through PJSUA-LIB, PJSUA2, or lower-level APIs. Package users can run `pjsua` as a configurable SIP endpoint for registration, calls, media tests, and protocol troubleshooting.
Why package nerds care
PJPROJECT packages a complete real-time communications stack rather than only a SIP parser: PJLIB portability primitives, SIP signaling, media processing, RTP, and NAT traversal are exposed through low-level libraries and the higher-level PJSUA and PJSUA2 APIs.
The included `pjsua` client also makes the library package useful for endpoint testing and troubleshooting, while packagers must account for codecs, TLS backends, audio/video systems, and platform-specific integrations.
Timeline
- 2005-02: PJSIP 0.2 became the first public release.
- 2007: The project began reporting routine testing at SIP interoperability events.
- 2010s: PJSUA2 added a higher-level C++ API and bindings-oriented application layer.
- 2020s: Continued releases expanded mobile, video, security, WebRTC, and real-time communication capabilities.
Related projects
- PJPROJECT contains the PJSIP signaling stack, PJMEDIA media framework, PJNATH NAT-traversal library, PJSUA-LIB C API, and PJSUA2 C++ API.
- SIPp is commonly useful for exercising SIP endpoints and scenarios, while Baresip and Sofia-SIP occupy neighboring command-line user-agent and SIP-library roles.
