CNAM and Toll Free Numbers

Question

Why doesn't my Toll Free number display the caller ID name I have requested and set up.

Applies To

Toll Free numbers in Account Manager and Configuration Manager and VCC

Answer

Toll Free numbers caller ID name is not handled the same way, industry wide, as a non Toll Free number.

With a non toll free number there is a tag(Destination Point Code) on the number so the receiving phone carrier knows which National CNAM database to pull the CNAM from.

Toll Free numbers do not have a tag (DPC), so the receiving phone carrier can only pull from their own internal database. Their own database may not have an entry for the number so all they can display is the number and words like "Toll Free Caller", or similar.

There is not a Single Central Repository for CNAM.
