The option of changing your caller id to provide a name is only available in certain markets.

In telegence, you have to make sure line number blocking isnt on. Some landline phones are diff as well....like on my cheap phone it says the same....but on my mother in laws, if she has me in the phones actual phone book with my name, then it shows my name.
