If the INVITE loops to your server, then you likely have an undesired 
t_relay() operation after a lookup() which only finds "Push 
Notification" contacts, which are not immediately routable.  Here, it 
would be helpful to provide the output of: "opensips-cli -x mi ul_dump", 
corresponding to the AoR you are trying to reach, right before placing 
the call.

Additionally, please post the full opensips.log, so we can see if the 
script logic post-lookup falls under "case 1" or "case 2".  Of course, 
in case of the latter, you should just "exit" the script without any 
further routing, as the INVITE will be put on hold, until a REGISTER 
arrives.

Indeed, the return value of that route will be ignored.  FYI, "exit;" 
implicitly returns 1 (success).

Yes, that is the main role of that route ("pn_send", as in: "Push 
Notification Send").
