Hi All I am using OpenSER as a proxy to make outbound calls my config is very simple if the number dialled is not an openser account route it to the PSTN gw.
if(does_uri_exist()){
# local uri does exist, is probably a user.
# lookup location
if(lookup("location")){
route(1);
return;
}
} else {
# probably a call to pstn....
route(2);
return;
}
and
route[2]
{
# pstn handling, simply route out to pstn.
sethostport("xx.xx.xx.xx:5060");
route(1);
}
The problem is that once the SIP packet arrives at the PSTN GW it does
NOT have the correct TO: set. Therefore the call does not get routed .
In the example below TO: is sip:[EMAIL PROTECTED] instead of
sip:[EMAIL PROTECTED]
Caller: ali [!at] jabber.splendor.net (replace the [!at] with a @)
Callee: 009613041708
