Is there a Fire/Burglar Alarm system wired to the phone?

Subject: [Full-Disclosure] Mystery phone lines, something is hiding and answ 
ering.

Hello,

I have been given the task of cleaning out all the old phone lines in 30+ 
restaurants. Some locations are 30 years old
and in the past, extra lines where added as needed, then forgotten about. My 
task it to figure out what lines we are using
so we can cancel the rest. 
I generally start at the equipment, (CC machine, FAX, Modem, etc) and get the 
numbers to the lines we are using, then
test the main breakout box that feeds the building and figure out what lines 
are coming into the building. Quite a easy
task as some of the buildings are over 50 years old and the breakout box is 
nothing but a chunk of wood with nuts and
bolts.

Anyway, on the 2 locations I have checked so far, I found 5 extra phone lines 
on one and 7 on the other. The strange
thing is, something computer related answers. Some lines have no answer,  but 
most, some computer picks up. On one,
I get some type of digital tone, but it does not sound like any modem I have 
ever heard.

I tried calling the numbers with my laptop and cell phone (with Caller ID 
turned off). Most of the lines won't connect with
No Carrier, but one, I get the string " ** 01 Communications TermServ **" and a 
login prompt.

Now if I disconnect the phone line from the break out box,  it stops answering, 
suggesting that whatever is answering, is
in the building.  Now in both locations, another store shares a wall. Napa on 
one and Boot Barn on the other. However, I
don't think they are using our phone box for their lines. I have yet to find a 
voice line, least one that someone answers.

Friday, I will be spending the day in a very hot place with a flashlight in one 
hand, and a toner in the other tracing wires,
but I was hoping that someone could give me some suggestions. I have never seen 
anything like this before and I am
stumped on what is going on.

Thanks for any and all help
Eddie
