[SR-Users] Tagging a call with custom pseudo variables - cfg 101

I think your best bet is to set those variables as AVPs, so that their
values can persist throughout the lifetime of the INVITE transaction.
That way you can also access them in onreply_route and failure_route,
which would not be the case with user variables ($var(...)). 

   request_route {
       # Initialise AVPs to $null or presumed default value.

       $avp(call_type) = $null;


       # When determination is made as to the call type:

       if($dbr(res=>[0,0]) eq 'vm')
	       $avp(call_type) = 'voicemail';

Basically WITH_VOICEMAIL in route LOCATION started sending the carrier calls to TOVOICEMAIL and it basically dies there. I can see the route(TOVOICEMAIL) line and can condition it out with an if but I really don't now how to differentiate between a ext to ext call or a outbound call in the cfg file. However given SQL I could.
