Hi all, I am just a newer on PJSIP, I develop a SIP VOIP software with PJSIP, I use the last version pjproject-1.0. There is a problem that, when an INVITE message is coming, the "on_incoming_call" is not called by the library. I have seen the example code in symbian_ua_gui project , but there is no different. Can anybody help me, or can you tell me how to debug it. Thanks a lot. Best Regards. Kevin -------------- next part -------------- An HTML attachment was scrubbed...
