Hello Sammy
No, I don't forget. My rtpproxy's startup script is "/usr/local/bin/rtpproxy -l 111.22.33.44/10.1.2.103 -s udp:10.1.2.103 19999 -F -m 36000 -M 36010 -d DBUG" I have forwarded the 36000~36010 port to rtpproxy server. Firewall ----------------------- Opensips/rtpproxy Server 111.22.33.44:5060 10.1.2.103:5050 111.22.33.44:36000/36010 10.1.2.103:36000/36010 But, Now sometime no audio. Do you have any suggest Thanks Nick From: [email protected] [mailto:[email protected]] On Behalf Of SamyGo Sent: Tuesday, September 11, 2012 10:28 AM To: OpenSIPS users mailling list Subject: Re: [OpenSIPS-Users] RTPPRoxy behind NAT Hi Nick, So you've forwarded the 5060 port to opensips server, cool. Did you forget to mention about the RTP ports forwarded to server ? Start RTPproxy with param -m and -M to assign range of RTP ports to use. Then forward that UDP port range to opensips server too. Then see what happens with audio. Also what is your total voip diagram with their network addresses.
