Benny, (1) Thanks for your reply. Yes, you are right. The problems related to the NAT. The problems are solved?by changing Port Range Forward of my router, and followed the suggestions in "Getting Around NAT". The detail is in my previous email. Thank you and others to document the steps and the debugging features of?PJ?to address the audio and other problems. They are very useful. (2) For this NAT issue, there should be a way to let RTP packets going through it?instead of changing the router. As mentioned before, if I use a softphone on the PC instead of pjsua with the same settings, that softphone figures out a way to receive the RTP packets. Just a thought.
