Hi all...
Well I have made some progress... Bellow is my routing statement:
route{ if (!mf_process_maxfwd_header("10")) { sl_send_reply("483","Too Many Hops"); break; }; if (msg:len >= 2048 ) { sl_send_reply("513", "Message too big"); break; }; if (!method=="REGISTER") record_route(); if (loose_route()) { append_hf("P-hint: rr-enforced\r\n"); route(1); break; };
if (!uri==myself) { append_hf("P-hint: outbound\r\n"); route(1); break; }; if (uri==myself) {
if (method=="REGISTER") {
save("location"); break; };
lookup("aliases"); if (!uri==myself) { append_hf("P-hint: outbound alias\r\n"); route(1); break; }; }; append_hf("P-hint: usrloc applied\r\n"); route(1); }
route[1] { if (src_ip==10.98.6.5) { if (dst_port==5065) { t_relay_to_tcp("10.98.118.20", "5065"); } else if (dst_port==5066) { t_relay_to_tcp("10.98.118.20", "5066"); } else if (dst_port==5067) { t_relay_to_tcp("10.98.118.20", "5067"); } else { t_relay_to_tcp("10.98.118.20", "5060"); } } else { t_relay_to_udp("10.98.6.5", "5060"); }; }
When asterisk sends a call to kamailio, Kamailio then sends the invite to 10.98.118.20 via TCP on port 5061. INVITE sip:1989@10.98.6.5:5061 SIP/2.0 Record-Route: sip:10.98.6.5:5065;transport=tcp;r2=on;lr=on Record-Route: sip:10.98.6.5:5061;r2=on;lr=on Via: SIP/2.0/TCP 10.98.6.5:5065;branch=z9hG4bK74fd.a4578a84.0 Via: SIP/2.0/UDP 10.98.6.5:5060;branch=z9hG4bK7b9bb22d;rport=5060 From: "1103" sip:1103@10.98.6.5;tag=as4ae41ccf To: sip:1989@10.98.6.5:5061 Contact: sip:1103@10.98.6.5 Call-ID: 44073b911e86b0a96c9104cb7a5ec389@10.98.6.5 CSeq: 102 INVITE User-Agent: Asterisk PBX Max-Forwards: 69 Date: Fri, 21 May 2010 12:23:58 GMT Allow: INVITE, ACK, CANCEL, OPTIONS, BYE, REFER, SUBSCRIBE, NOTIFY, INFO Supported: replaces Content-Type: application/sdp Content-Length: 232 P-hint: usrloc applied
The problem is that the Kamailio receives a 302 Moved Temporarily with a contact field of CONTACT: sip:1989@10.98.6.5:5065;transport=TCP I need to have Kamailio, use this contact field and re-send the invite.
How can this be done?
