My understanding was that in the United States, the Caller ID name that's displayed goes through a lookup an an LIDB database for displaying the CNAM of the calling party. When I was doing some testing this weekend, I noticed that when I called my Visible (the Verizon owned MVNO) phone, it displayed the CNAM I had set with Asteriisk in the SIP INVITE.
Is this normal? Do some providers directly display the sent CNAM like this?
