[OpenSIPS-Users] trouble with event_route.

[johan]

following Volga's advice, I added lookup(location)  after the subscribe 
but to no avail, that event doesn't want to pop.


         xlog("callid=$ci: Route[userlocation]:we call t_newtran and 
subscribe for E_UL_CONTACT_INSERT");
         # prepare transaction for branch injection; it is mandatory
         # to create the transaction before the subscription, otherwise
         # the EBR module will not pass the transaction ID into the
         # notification route
         t_newtran();
         # keep the transaction alive (even if all branches will
         # terminate) until the FR INVITE timer hits (we want to wait
         # for new possible contacts being registered)
         t_wait_for_new_branches();
         # subscribe to new contact registration event,
         # but for our callee only
         $avp(filter) = "aor=" + $tU + "@" + $td;
         $avp(filter) = "aor=*";
         xlog("callid=$ci: Route[userlocation]: filter avp(filter) 
[$avp(filter)]");
         #async( wait_for_event("E_UL_CONTACT_INSERT",$avp(filter), 40), 
"fork_call");
notify_on_event("E_UL_CONTACT_INSERT",$avp(filter),"fork_call", 180);

         if (lookup("location"))
         {
             route(relay);
         }


Is there somebody out there who did this on 3.1 ?
