>From comp.modems, with obvious applicability to comp.dcom.telecom:

QUOTED TEXT FOLLOWS:

There's been a lot of talk about Caller ID in [comp.modems] lately, so
I thought I would add a Caller ID question, only indirectly related to
modems.

What happens if you have Call Waiting and Caller ID, and a call comes
in while your connected elsewhere? I presume what happens is you just
don't get any caller id info on the waiting call, whether or not you
accept it. My understanding is that the caller id info is part of the
ring signal, and if it doesn't ring you don't get the info.

The reason this is partly related to modems is my pet peeve with TB
modems in PEP mode. PEP mode generally retrains around the call
waiting beep, without ever letting you know about it.  This is what
many people want, but not what I want. I would rather drop the data
call and get the incoming call. If Caller ID worked with Call Waiting,
I could rig something up.

[Moderator's Note: I've wondered about this myself. How does the
Caller IB box get anything to dislay when the calls comes in via
call-waiting? If you hang up and let the new call actually ring in,
does the information pass at that time, or not?  Likewise, when your
phone is forwarded, we all know there is a single ring to remind you
of the forwarding, but you cannot actually receive the call no matter
how fast you pick up the receiver. Is the Caller ID sent to you on
those calls, or not?    PAT]
