About PJSIP
A mature SIP stack turns its attention to concurrency correctness and AI voice endpoints
PJSIP remains the reference open-source SIP and media stack for embedded and mobile softphones, shipping roughly one feature release a year. Version 2.17 pairs asynchronous client authentication with a documented real-time AI speech connectivity path, alongside ten separate deadlock fixes. The cadence is slow, but each drop carries a backward-incompatibility section integrators have to read before upgrading.
