[SR-Users] Kamailio Bridge

Hello, I am trying to set up a Kamailio in Bridge Mode with two interfaces using rtpproxy. The problem I have is SDP information port and IP is not updated from outside to inside. But on the other hand the SDP is rewrited from inside to outside. In the rtpproxy log I am seeing this error: Mar 21 14:21:21 kamailio rtpproxy[6119]: ERR:create_twinlistener: can't bind to the IPv4 port 23414: Cannot assign requested address Mar 21 14:21:21 kamailio rtpproxy[6119]: ERR:handle_command: can't create listener and in kamailio log: ERROR: rtpproxy [rtpproxy.c:2727]: force_rtp_proxy(): incorrect port 0 in reply from rtp proxy Something strange and interesting is the port that shows up in the RTPPROXY error (23414) does not corresponds to any ports used. Thank you Nelson.- --------------------------------------------------------------------------------------------------------------------------------------------- Everything is set up this way: Kamailio Asterisk (asterisk-inside-ip) <-> Kamailio (inside-kamailio-ip) / Kamailio (outside-kamailio-ip) <-> sip-vendor-ip listen=inside-kamailio-ip listen=outside-kamailio-ip mhomed=1 if(src_ip=="asterisk-inside-ip"){ rtpproxy_manage("faie"); } if(src_ip=="sip-vendor-ip"){ rtpproxy_manage("faie"); } rtpproxy OPTIONS="rtpproxy -l inside-kamailio-ip/outside-kamailio-ip -m 20000 -M 30000 -u rtpproxy:rtpproxy -p /var/run/rtpproxy/rtpproxy.pid -s udp: 127.0.0.1:7722 -d DBUG:LOG_LOCAL6" ---------------------------------------------------------------------------------------------------------------------------------------------- SIP TRACES 2016/03/21 14:46:52.121472 asterisk-inside-ip:5060 -> inside-kamailio-ip:5060 INVITE sip:999999999@inside-kamailio-ip SIP/2.0 Via: SIP/2.0/UDP asterisk-inside-ip:5060;branch=z9hG4bK7f1ece8e;rport Max-Forwards: 70 From: 111111111<sip:1000@asterisk-inside-ip>;tag=as497457e6 To: <sip:999999999@inside-kamailio-ip> Contact: <sip:1000@asterisk-inside-ip:5060> Call-ID: 57bd4ca457972f5a42502ba34bba4500@asterisk-inside-ip:5060 CSeq: 102 INVITE User-Agent: Abantix Date: Mon, 21 Mar 2016 13:46:52 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO, PUBLISH Supported: replaces, timer Remote-Party-ID: <sip:888888888@local-domain ;user=phone>;privacy=off;party=calling Content-Type: application/sdp Content-Length: 251 v=0 o=root 478097443 478097443 IN IP4 asterisk-inside-ip ########## ASTERISK IP s=asterisk c=IN IP4 asterisk-inside-ip ########## ASTERISK IP t=0 0 m=audio 17146 RTP/AVP 8 101 ########## ASTERISK PORT a=rtpmap:8 PCMA/8000 a=rtpmap:101 telephone-event/8000 a=fmtp:101 0-16 a=silenceSupp:off -
