[SR-Users] Need help with route statement
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.

The problem is that the Kamailio receives a 302 Moved Temporarily with a
contact field of CONTACT:
I need to have Kamailio, use this contact field and re-send the invite.
How can this be done?

Re: [SR-Users] Need help with route statement
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");

Re: [SR-Users] Need help with route statement
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.
