The original poster's writing was a bit vague, but I got the
impression he was talking about a calling card that was actually part
of his main landline phone service.

I know that some of the Bells, some of the time ... did, indeed, send
over the CNID of the home telephone/account number in the Bad Old
Days. But it's been a decade, or longer, since I've used or had any
friends using them, so have no idea how long this lasted.

(We looked into this option about five years ago for corporate use -
we wanted people to be able to call out from home or offsite or at
lunch.. and have the CNID show their work number. Think, oh, a teacher
or doctor calling from home. We weren't able to find anyone set up for

There are some folk _today_ who'll reset the CNID for you to whatever
you wish when you make the call. Check out, for example,

(no connection with them aside from having tested their service).

Knowledge may be power, but communications is the key
