[OpenSIPS-Users] SIP/2.0 477 Send failed (477/TM) - Route

[Vlad Paiu]

Hello,

What you can do is send the call to a destination which is not available 
at all, control the amount of time you want to give the client to 
register via the fr_timer, and when that timeout is exceeded try to 
route the call to the client.

Short snippet of code would be

if (!t_relay("3"))
{
         if((is_method("INVITE")))
         {
                 exec_avp("some script to wake-up the client");
                 # relay to localhost, discart port
                 $du = "sip:127.0.0.1:9";
                 # wait two seconds for the client to register
                 $T_fr_timeout = 2;
                 t_on_failure("route_to_client");
                 t_relay();
                 exit;
         }
}

failure_route[route_to_client] {
     if (t_was_cancelled())
         exit;

     # after two seconds, this will get called
     # see if the client is registered now

     lookup("location");
     t_relay();
     exit;
}
