Hi All,
I am having a weird problem with t_relay when calling it from route[2] in
the script below.
The problem that I am experiencing is that it does not relay the message to
the modified destination uri host/port. Instead it relays the message to the
modified uri/host/port from route[1].
I initially thought the problem was with my tncgw_route custom module that
modifies the msg->new_uri
but after some testing and debugging I realized that if I modify the
destination uri host/port with rewritehostport functino on route[2]
t_relay() is also failing (sending the message to the modified uri in
route[1]).
Then I decided to try t_relay("udp:host:port") instead of t_relay() on
route[2] and it worked fine. So the question is why does t_relay() is not
picking the msg->new_uri when called from route[2]?.
route[1] {
setflag(22);
# send it out now; use stateful forwarding as it works reliably
# even for UDP2TCP
if (method=="INVITE"){
t_on_failure("1");
t_on_reply("1");
$var(route_result)=tncgw_route("1");
tncgw_cdr();
if($var(route_result)==-404){
xlog("Invalid Route send 404 \n");
sl_send_reply("404","Invalid Route");
tncgw_releasecdr("404","SB Invalid Route");
exit;
}
if($var(route_result)==-503){
xlog("Congestion, send 503 \n");
sl_send_reply("503","No route available for
destination");
tncgw_releasecdr("503","SB No route available for
destination");
exit;
}
if($var(route_result)<0){
xlog("Call not routed\n");
sl_send_reply("503","No route available for
destination");
tncgw_releasecdr("$var(route_result)","SB Call not
routed");
exit;
}
t_relay();
exit;
}
}
route[2] {
setflag(22);
# send it out now; use stateful forwarding as it works reliably
# even for UDP2TCP
t_on_reply("2");
$var(route_result)=tncgw_route("2");
tncgw_cdr();
if($var(route_result)==-404){
xlog("Invalid Route send 404 \n");
sl_send_reply("404","Invalid Route");
tncgw_releasecdr("404","SB Invalid Route");
exit;
}
if($var(route_result)==-503){
xlog("Congestion, send 503 \n");
sl_send_reply("503","No route available for destination");
tncgw_releasecdr("503","SB No route available for
destination");
exit;
}
if($var(route_result)<0){
xlog("Call not routed\n");
sl_send_reply("503","SB No route available for destination");
tncgw_releasecdr("$var(route_result)","SB Call not routed");
exit;
}
if (!t_relay()){
sl_reply_error();
};
}
failure_route[1] {
setflag(22);
if(status=~"3[0-9][0-9]|4[0-9][0-9]|5[0-9][0-9]|6[0-9][0-9]")
{
/*
if first carrier failed the call then try the next in route
*/
append_branch();
route(2);
exit;
}
}
onreply_route[1] {
setflag(22);
if (status=~"3[0-9][0-9]|4[0-9][0-9]|5[0-9][0-9]|6[0-9][0-9]") {
# Response from carrier
tncgw_releasecdr("$rs","From Carrier");
}
}
I appreciate any help.
Thank you.
Chevio
