Hello,

You cannot handle SIP eventualities by checking the return value of t_relay(); a call to t_relay() will almost always succeed immediately, unless there is an a priori failure out of hand (e.g. cannot send from socket, DNS lookup failure, etc.).

Instead, you must do this in a failure_route:

route { ... t_on_failure("FAILURE_ROUTE");

if(!t_relay())
   sl_reply_error();

}

failure_route[FAILURE_ROUTE] { if(t_is_canceled()) exit;

if(t_branch_timeout()) {
   # Handle your timeout case here.

   $ru = new value etc.

   t_relay();
   exit;
}

}
