VoIP applications compiled under Ubuntu 14.04 ffmpeg libX264 and Pjsip

Pjsip is an open source SIP protocol stack.  It supports a wide range of SIP extensions and is arguably one of the most popular sip stacks. It implements SIP, SDP, RTP, STUN, turn, and ice. PJSIP provides a very clear API as well as NAT traversal capabilities as a SIP-based multimedia communication framework. Pjsip is very well-ported and supports almost all today's systems: from desktop systems to embedded systems to smartphones. Pjsip also supports voice, video, status rendering, and instant messaging.

Pjsip is very powerful, many VoIP voice video calling applications use it ...
