1. analyze the RURI to find out if the called user is a phone number, e.g.:

if ($rU ~= "\+1[1-9]*") {
   route(11); # PSTN
} else {
   route(12); # local user
}
exit;

2. route to gateway

route[11] {
   # if needed apply number reformating if the dialing plan
   # of the SIP proxy is different then the  dialing plan of the
   # gateway. we change the userpart of the request URI (RURI)
   strip(1);
   prefix("00");

   # send to gateway. for example by changing the host-part
   # of RURI
   $rd = "1.2.3.4"; # IP address of the gateway

   # forward to gateway and exit;
   t_relay();
   exit;
}
