Pat,

I'm trying to find a device that lights up when a phone extension is
picked up. That way I can know if a phone line with multiple
extensions is in use without picking up the phone itself. I looked in
HELLO DIRECT, but they don't ahve anything like that. If you don't
know of the top of your head, can you direct me to a mail order
company that might carry things like that.

Thank you,

Craig Steinberger

[Moderator's Note: We have discussed this many times in the Digest.
Would one of you readers with a schmatic send it along to Craig, with
a parts list, etc.  Thanks.  PAT]
