the extension 123 and 202 is in the same netwotk behind a symmetric nat and my server this in another network and he has an ip public . the problem is that when those extensions call there is not you bidirectional audio, alone in one of them I see in the sdp of the message that the proxy puts me an a=nortpproxy:yes and not you because! ideas as solving this problem? v=0 o=202 8000 8000 IN IP4 192.168.10.40 s=SIP Call c=IN IP4 190.184.22.152 t=0 0 m=audio 35036 RTP/AVP 18 101 a=sendrecv a=rtpmap:18 G729/8000 a=ptime:20 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-11 a=nortpproxy:yes regards rickygm
