Re: [Kamailio-Users] ACK/BYE problem with NAT

sorry, I sent wrong part of cfg... if((t_check_status("200|183|180") && search("Content_Type: application/sdp")) || search("Content-Type: application/sdp")) { fix_nated_contact(); force_rtp_proxy(); } I get this "incorect port 0..." error when it comes to "force_rtp_proxy" in above statement. flag 5 is not set so it never enters "isflagset(5)..." statement.

STUN and ICE are disabled in UAC#2. Other way is working OK (UAC#2 --INVITE--> UAC#1), RTPProxy is in the middle,... Kamailio is aware that UAC#2 is behind NAT and adds received filed on REGISTER. MySQL location table: contact received sip:bob@10.2.4.18:1025;rinstance=24c6e191484e570a sip:UAC#2_PUBLIC_IP_ADDRESS:55671 Why proxy is not aware that UAC#2 is behind NAT (for BYE and ACK) when call is initiated by UAC#1 and thus sends ACK/BYE to private IP address? Shouldn't Contact header be rewriten with NAT address/port and also a "c" filed in SDP with RTPProxy address? fix_nated_contact() sholud fix contact header for transaction-starting messages like ACK and BYE... I'm using kamailio 1.5.1-tls and standard kamailio.cfg (to be sure that I'm not using my cfg which could be faulty)...
