AT&T provides caller identification over a Primary Rate Interface D
channel in real time as an ISDN service. (Although it does not exactly
conform to Q.931)  This is not the same as providing the information on
tape once a month for billing purposes.  The service is specifically
designed for telemarketing firms to be used to look up customer records.
It is CLI, not ANI.
