Hello, ? It's my first post :-) ? It's a quite stupid question, what SIP server and SIP client do you guys use to test PJSIP client against? 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...
