[OpenSIPS-Users] trouble with event_route.

[johan]

it finally works.

The problem was that I listened for the wrong event.

In case the user is registered you need to listen for E_UL_CONTACT_UPDATE:

         $avp(filter) = "aor="+$rU;
         xlog("callid=$ci: Route[userlocationfork]: filter avp(filter) 
[$avp(filter)]");
notify_on_event("E_UL_CONTACT_UPDATE",$avp(filter),"fork_call", 7200);
