Hi, we have over the last year tested PJSIP against several different SIP servers and PBX's (OpenSER, Avaya, Brekeke,...) and against several different phones (Snom, Polycom, Grandstream, Eyebeam, ..) So far it all works well, at least for us. Are you sure this is not a configuration issue, either on PJSIP or on server? If you are behind NAT a STUN server and enabling ICE will help a lot, but check that the other clients support ICE as well.

I'm asking this question because I tested PJSIP client against iptel sip server, X-Lite sip client and some other sip clients, but none of them really worked perfectly with PJSIP, especially when I tested inside company firewall. Any suggestions are welcome! thanks! wwzhdo -------------- next part -------------- An HTML attachment was scrubbed...
