Hi Guys,
my scneario is the following:
UA -------> Opensips 1.6.24 --------> Asterisk 1.4.23
Im using drouting to do failover to my Asterisk Machines
(10.0.20.124:5060,10.0.20.134:5060,10.0.20.131:5060).
Opensips runs on 10.0.20.124:5080. When routing to the asterisk on the same
machine it works like a charm.
When routing to machines with other ips than my own, the following scenario
accurs:
Opensips Asterisk
INVITE --------->
<---------------SIP OK
---> ACK
<---------------SIP OK
---> ACK
<---------------SIP OK
---> ACK
<---------------SIP OK
---> ACK
So the SIP OK will be retransmitted 6 times after the channel hangs up. In the
logs of opensips i see the SIP OK is getting there and an ACK will be
transmitted to the correct IP. It never arrives though.
I've already tried using a nat account on the asterisk. It doesn't work.
What am I doing wrong?
Please find my route conf below:
route{
if(!allow_routing())
{ sl_send_reply("503","Service Unavailable");
exit;
}
if (!mf_process_maxfwd_header("10")) {
sl_send_reply("483","Too Many Hops");
exit;
}
if (msg:len >= 2048 ) {
sl_send_reply("513", "Message too big");
exit;
};
#initial requests
# CANCEL processing
if (is_method("CANCEL")) {
if (t_check_trans())
t_relay();
exit;
}
t_check_trans();
if (!method=="REGISTER")
record_route();
if (loose_route()) {
xlog("loosing route\n");
# mark routing logic in request
append_hf("P-hint: rr-enforced\r\n");
route(1);
};
if (!uri==myself) {
# mark routing logic in request
append_hf("P-hint: outbound\r\n");
route(1);
};
if(method=="INVITE"){
route(4);
}
# with proper names and addresses in it)
if (uri==myself) {
# presence handling
if (method=="REGISTER") {
# Uncomment this if you want to use digest
authentication
save("location");
if (!www_authorize("", "subscriber")) {
www_challenge("", "0");
exit;
};
exit;
# native SIP destinations are handled using our USRLOC DB
if (!lookup("location")) {
#sl_send_reply("404", "Not Found");
#rewritehostport("10.0.20.124:5060");
route(1);
exit;
};
append_hf("P-hint: usrloc applied\r\n");
}
setflag(2);
route(1);
}
}
route[1] {
if (!t_relay()) {
sl_reply_error();
};
exit;
}
#dynamische route
route[4] {
rewritehostport("10.0.20.134:5060");
if (!do_routing("0")) {
send_reply("503", "No Rules matching the URI");
exit;
}
if (is_method("INVITE")) {
t_on_failure("4");
}
route(1);
}
onreply_route[2]{
xlog("L_INFO","Got reply 2\n");
}
failure_route[1] {
if (t_was_cancelled()) {
exit;
}
}
branch_route[2]{
xlog("L_INFO","branching route 2\n");
}
branch_route[4]{
xlog("L_INFO","branching route 4\n");
}
failure_route[4] {
xlog("L_INFO","having failure route 4\n");
if (t_was_cancelled()) {
xlog("L_INFO","route 4 cancelled\n");
exit;
}
if (use_next_gw()) {
xlog("next gw\n");
t_relay();
xlog("relay done\n");
exit;
} else {
t_reply ("503", "Service not available");
exit;
}
if (t_check_status("[34][0-9][0-9]")) {
exit;
}
}
