Are their any special PRI gateway configs that need to be done to get 711 dialing to work correctly. The called number is being sent to the carrier correctly which then initiates the 1-800 number to the 711 service center, but once it reaches that point it comes up undefined. So, the 711 service center rejects the call. The carrier did recognize a parameter coming across in the dial trace, "originating number path screening." Neither one of use knew what that was, but was originating from the CCM system. Thanks.
