This would actually work if their carrier had been setting the ANI as 
their billing telephone number, and letting them only change the 
CallingPartyNumber field.

what the switches are supposed to route based on.

Are you doing the tollfree dips yourself, or are you sending them 
untranslated to another carrier for dip and termination?
