The Asterisk project is now using PJSIP as their SIP stack. It's right now in trunk and will be part of Asterisk 12.

Most of the trails I've seen on the mailing list have been about using PJSIP for SIP clients, but is anyone using it (like us) server-side, e.g. for proxies or B2BUAs? Each instance of our "bono" edge proxy server supports 50000 incoming SIP/TCP connections (and the limitation we then hit is with Amazon AWS EC2, not the software itself), but we're unable to have more than one transport thread (i.e. running pjsip_endpt_handle_events). If we have more than one, we see crashes that seem to be related to concurrent accesses to shared data structures from multiple threads. > > Does anyone have any experience of running multiple transport threads, or any pointers for using PJSIP at high scale? I'm happy to investigate more (and share crash dumps if that's useful), but wanted to check whether anyone else had seen this first. > > Thanks, > > Matt > > _______________________________________________ > Visit our blog: http://blog.pjsip.org > > pjsip mailing list > pjsip at lists.pjsip.org > http://lists.pjsip.org/mailman/listinfo/pjsip_lists.pjsip.org -- Sa?l Ibarra Corretg?
