Yes...I mean no...well, sorta...
When the local exchange carrier (LEC) receives the CID number from your cell phone provider, it looks up the number in a third party CNAM database. Different LECs use different calling name database services.
So, BellSouth may be using the Verisign database and Verizon may be using the Syniverse database (just for example, I really don't know). If the Verisign CNAM database has been updated with your name/number then BellSouth CID subscribers will get your correct name. If the Syniverse database just identifies your number as a Cellular Call, Verizon CID subscribers get "Cellular Call" on their screen when you call.
The same thing happens to me. If I call a customer, from my cell, in Gainesvlle (BellSouth) they can see my name. If I call a customer in Ocala (Sprint) they get "Florida Call" just as they would with any other Alltel cell phone. Annoying, isn't it?
So, it may be that AT&T hasn't updated with all of the CNAM database providers, or it may be that some CNAM providers just don't care about cell phone numbers because they get changed so often. I don't know. I do know that life is too short to try to get this info changed!
I'm sure someone else may be able to shed more light on this than me. They may also correct some of my terminology.
