PJSIP 1.8.5

PJSIP is a protocol stack, designed to have high performance, be very small in footprint, and very flexible.

Here are some key features of "PJSIP":

· Extremely portable: Write the application once, and it would run on many many platforms (all Windows flavors, Windows Mobile, Linux, all Unix flavors, MacOS X, RTEMS, Symbian OS, etc.)
· Very small footprint: With less than 150KB for complete SIP features, PJSIP is ideal not only for embedded development where space is costly but also for general applications where smaller size means shorter download time for users.
· High performance: Which means less CPU power requirement and more SIP transactions/calls can be handled per second.
· Many features: Many SIP features/extensions such as multiple usages in dialog, event subscription framework, presence, instant messaging, call transfer, etc. have been implemented in the library.
· Extensive SIP documentation: There can never be enough documentation, so we try to provide fellow developers with hundreds of pages worth of documentation.
