Im not a code expert or a kamailio expert, so where and how do I intergrate this function in my current routing logic?

# main request routing logic

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) {

if (method=="REGISTER") {

save("location"); 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"); }; }

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?

Use get_redirects() frunction

Hi!

Please post the complete SIP trace of the scenario which does not work, this means:

incoming INVITE, outgoing INVITE, incoming response, outgoing response

also you can increase loglevel (debug=3 for kamailio 3.0, debug=4 for kamailio 1.5) and watch syslog.
