Subject: junk calls; call forwarding
I have heard of junk calls being routed to every possible number, thus
stripping away the protection afforded by unlisted numbers (and also
reaching jails, hospitals, etc.). I have also heard of not being able
to hang up on some of these calls, which spells trouble if you happen
to want to make emergency call at the very same time (it's happened!).
But I am not sure who said what (if anything) about such junk calls.
Re: call forwarding. I can still make outgoing calls, right? If I am
making such an outgoing call and a call comes in, do I hear anything?
(If the phone is on the hook, I hear one ring on an incoming call but
cannot answer it there, right?)

There are a number of common uses for the other two wires. The most likely
use in this case is for the 'A-A1' lines -- an off-hook signal used by
key phone systems to deal with someone picking up a held line, lighting
the buttons to show a line is in use, etc. If that's the case, the
answering machine should simply complete a circuit between those two when
it's off-hook.

I suspect that activity of this sort will decrease when we all have those
little boxes that tell us the number of the phone that is calling us. (They
were testing them in Pennsylvania a year ago.) Then you at least have some
information to give to the phone company when you report those harassing phone
calls. You could even take it upon yourself to prevent them from harassing
others by tying up THEIR dialout line with YOUR autodialer.

Getting an unlisted number might not help.
When I was in high-school I worked for a Telephone Sales company
(selling Newspapers). We were gived a card with the first
5 digits and had to dial the 100 last 2 digit combinations.
This way we got all the unlisted numbers...
