RE: [Serusers] Mediaproxy, problems in PSTN-to-SIP

Yes, it is running. I can see it with a ps -aux, and it is well configured in my ser.cfg In fact: - If I have to UAs, both behind same (linux-iptables) nat, I have a two-way audio communication, with nice quality, with no problems at all. - If I place a call to the PSTN, trough my Gateway, from my UA, I have a two-way audio communication, with nice quality, with no problems at all. But ... - If I try to receive a call from the PSTN, trough my Gateway, I only have a one-way audio communication, but only in the SIP->PSTN direction. look at what session.py showed when making calls from the pstn ... Caller Via Called Status Duration Codec Type Traffic ------------------------------------------------------------------------ --------------------------- IP_CISCO:20482 - ip_mediaproxy:35234 - ?.?.?.?:? inactive 1'04" G729 Audio 11.29k/0/0 In some way, it cannot get the IP address of my UA ... and I do not why. The intereseting sing is that signalling gets completed, because my UA receives the last ACK ( from the proxy ) and starts sending RTP, but to the Gateway instead of sending it to the mediaproxy. Look at some tcpduming obtained at the UA (behind nat) ... - tcpdumping RTP on the UA (private IP:192.168.1.185.15090) 20:36:37.596851 192.168.1.185.15090 > IP_CISCO.20482: udp 32 Do you see? It sends RTP packets to the IP:PORT of my cisco ... And, lastly, if you see the active calls at the cisco, you'll see the following ... - show call active voice brief 2D2B : 104269100hs.1 +273 pid:1991334 Originate 1991015 active dur 00:00:36 tx:162/3202 rx:1790/35800 IP ip_ser_mediaproxy:35234 rtt:0ms pl:33170/140ms lost:0/0/0 delay:69/69/70ms g729r8 So the cisco is communicating in a nice way with the proxy, but the proxy is not forwarding any rtp traffic to my UA.
