[comp.dcom.telecom] Caller ID On My FAX Machine?

RPG@heap.cisco.com (Richard P. Gruen) (11/07/89)

My FAX machine (a Murata M1200) reports on the last 20 calls, be they
transmit or receive, placed or received.  There's a space in the call
log for "Location" which in about a third of the cases shows a
ten-digit phone number.  This is true for local calls which I dial
with 7-digit numbers; for intra-LATA 10-digit calls; for genuine long
distance calls (although if I dial a leading 1, the log doesn't show
it); and even a 10-digit translation of the telephone number i reached
after i used an 800 number which showed the actual area code and phone
number instead of the 800 number.

I've gotten a number back even when the other party's header line (the
one with their time and date and logo) didn't have an included FAX
number.

So the question is, am i seeing Caller ID, or is there some part of
the G3 FAX protocol which provides these numbers?  If it's caller ID,
can I suppress it?

[Moderator's Note: I think what you are seeing is simply the phone
number programmed into the handshaking routine on the other modem.
This is just whatever the other party decides to put in there. We have
the same thing on the faxes in our office. You could as easily program
the phrase '000-000-0000 Not Your Business, Inc' in there as you could
give the true phone number and your company name.  PT]
