The Total Lowdown on COCOTs
by: Bungalow Bill
Thanks: Count Zero
Hello: Liquid Jesus, Damm

Note: If you want to cut through my ramblings on how a COCOT actually
works, and just learn how to phreak from them, just read what's in
between the *s.
Ok, you've all seen the comercials on tv talking about NYNEX telephones,
and how other phones are unreliable, and charge lots more, etc etc etc.
And you might think, "Yeah sure, there's no such thing as a non-NYNEX
payphone." Well, just because you've never seen one, doesn't necesarily
mean they don't exist. These other phones are the COCOTs. COCOT stands
for Customer Owned Coin Operated Telephone. All a COCOT is is a phone
that a private owner rents, leases, or buys from a company. The COCOT is
hooked into the regular customer loop, as opposed to the seperate data
loops NYNEX payphones operate on. What that means is, when you dial a
local call, you put in a quarter, and the owner just gets his monthly
bill from NYNEX. He get's fifteen cents for each call you make, because
it only costs him ten cents for the call. So when you get a COCOT, the
company sends you a phone, a key, and instructions. Whenever you need
some change, you run to your COCOT, open it up, and get the change out.
So you're probably thinking, "Yeah, great, cut the bullshit and tell me
how to steal calls from one." Ok, here's the info. When you pick up the
handset, the dialtone you are hearing is not coming from the CO, but
rather, from inside the COCOT. So in essence, what you are hearing is a
fake dialtone. Aurally, you can't tell the difference. But before you get
to the real dialtone, you must put in a quarter. Here's the catch. By
law, 800 numbers (ie, toll free numbers) must be free from payphones. So
here's what you do. *Pick up the phone, and dial any 800 number. Try,
1-800-loan-yes. When the person answers, just sit there quietly, until
they hang up. Or, if you're feeling particularly, evil, tell the
operator, "Oh, sorry, I meant to dial 1-800-usa-loan." When she hangs up,
wait for a few moments. You will most likely hear some clicks, hissing,
or other noise. Then you will get a dialtone. This is the real, unsuped
dialtone. Any call you make now is being billed to the customer's loop.
So if you call a 900 number, or long distance, he will see it on his
bill. Ok, so now you start hitting keypad numbers to dial, and "Hey, I
don't hear anything!" Well, on many COCOTs, the keypad is disabled until
it knows there is a quarter in there. There is no way around this, unless
you have your trusty Rat Shack tone dialer (and you'd better, or you
stink). Just hold this up to the phone and dial away.* But that's not all
that's interesting about COCOTs. You will notice that the COCOT doesn't
have the number for it anywhere on it. There is a great reason for this.
It's because if you dial into the phone, it won't ring. Instead, you get
a synthesized voice reading you a menu of the phone's maintenence
routines. These can be very useful, because you can do all sorts of
interesting things with this, not the least of which is to access the
COCOT's 300 baud modem. Yeah, there's a modem in there too. I'm not sure
what it's used for, but if we could reverse-engineer it, then maybe we
could tote a laptop down there w/out a modem and still dial up boards.
Granted, it'd be damned slow. If you want the number for the COCOT, pick
up it's handset, and dial 1-800-my-ani-is. You will hear a recording that
tells you the phone number for the phone. Whoopee! That's all for this
file. Look for more knowledge and wisdom from the Omega bbs's co-SysOps,
Epidemic and Bungalow Bill. The information below is brought to you
