Hello merlin,
First of all, from a user's perspective, a Post-Dial Delay of up to 30
seconds should be quite annoying. Your SIP logic will also increase the
amount of traffic received by your platform, due to lots of
retransmissions for all failed calls.
That being said, here is what you should add in order to make it work:
t_newtran();
...
while (...) {
if (t_was_cancelled()) {
t_reply("487", "Request Cancelled");
exit;
}
...
}

*Subject:* how to cancel an INVITE before the callee receive it?
Hi all,
Let me describe my scenario first.
if the callee is not online, opensips will wait for 30s.
During the 30s, if the callee be online, opensips will send the
invite to it.
$avp(timeout) = 30 ;
while( !lookup("location","m") ){
if( $avp(timeout)==0 ){
send_reply("420","Can not find the callee!");
exit;
}
sleep("1");
$avp(timeout) = $avp(timeout)-1;
}
This works well, the only problem is the caller can not cancel it
during that 30s
t_cancel_branch() only can be used in onreply_route, but at that
time, callee is offline.
My question is :
Is it possible that terminate a request in route block?
