Customer Owned Coin Operated
The COCOT pay phone (Customer Owned Coin
Operated Telephone) is a result of the divestiture of AT&T in 1984, thereby
bringing competition to the telephone industry in many areas. Pay phones
were part of this competition and shortly after divestiture, there were
many companies that jumped on the bandwagon to make these "fake'" pay
phones and cash in. COCOTs are not limited to the USA as they are now
commonly found in Canada and other countries where the telephone company
monopolies are being divested.

These pictures were found on other websites on the Internet. I do not own
any of these phones.
Overview on COCOTs
The COCOT pay phone is different than the
regular telephone company (telco) pay phone since it must do all the rate
information and "billing" for dialed direct (non-operator assisted/calling
card calls) inside the phone rather than relying on the telco switch to do
it all. This is accomplished by a built-in computer - which handles all
customer-interface by a LCD screen (sometimes even an LED screen) and
COCOT providers can check and/or change the settings on the phone remotely.
The phone itself contains a special computer modem inside where the COCOT
provider can dial it up and access the internal computer of the COCOT.
Examples of COCOT Phones
There many examples of COCOT phones used in
the USA and Canada. Some of these are old traditional telephone company type
pay phone housings (WECO Fortress, AE/GTE Fortress, Nortel Centurion, etc)
with new electronics inside. Others are copies of the WECO Fortress, and
still others are of original design.
QuorTech (formerly Elcotel) COCOT Phones
is one of the leading makers of COCOT phones in the USA. The Western
Electric Fortress (originally made by Western Electric / Lucent) is now known
It is now owned, manufactured, and refurbished by QuorTech Solutions.
Offering user and operator familiarity, the Western Electric style
payphone is the industry standard and is the most widely utilized payphone
in the USA.
Protel COCOT Phones
is the other leading maker of COCOT phones in the USA. The pay phone shown
here is a Western Electric look-alike called the Sentinel. Notice that the
handset cord comes out of the left side of the pay phone, and the coin
return is on the right side of the pay phone.
They also make other kinds of pay phones
and the electronics to retrofit payphones to make them "smart". They also
make the "Ascension" phone, which looks very much like a
QuorTech (formerly Nortel) Millennium
Millennium (formerly made by Nortel) is a very sophisticated COCOT
phone. Not only does it handle all the coin functions internally as do
regular COCOTS, but it also has a calling card/credit card reader slot and
several speed-dial buttons. The one shown here is the "Multi-Pay" version.
There are desktop versions and a "Coin-Only" version without the card
These are used in a number of places throughout Canada and in the USA. USA
examples for regular telcos include old GTE areas of Verizon, the local
and COCOT divisions of Sprint, and the local division of Qwest. Other COCOT
companies also use Millenniums.
AT&T Public Phone 2000
a normal COCOT by the normal sense, AT&T made a COCOT called the Public
Phone 2000. It debuted in 1991.
At one time, this was commonly found in airports but no where else as far as I know of. It
was designed to be an all-in-one unit for accessing E-mail, faxes,
computers, etc. It has a full keyboard for text messaging.
It does not take coins, but has a slot for a calling card/credit card.
A word on Alternative Operator Services (AOS)
With the divestiture of AT&T, not only were
long distance and pay phones open to competition, but so were operator
services. Instead of going through "Ma Bell" to handle the calling card and
collect calls, COCOT people discovered if they use AOS services, they could
cash in on more profits.
AOS services handle many of the long-distance operator functions of a telco
operator - including collect and calling card calls.
AOS services are accessed by the COCOT when the customer of the COCOT dials
a 0+ number. The phone stores the number, then dials a 1-800 number to the
AOS service. When the AOS computer answers, a dial tone is presented and the
COCOT dials its own number (a simple form of Automatic Number Identification
or ANI) , then it dials 0+ area code+number - all using DTMF (touch tone)
AOS services are independent services that may or may not be related to the
COCOT telephone company. AOS companies include OCI and US Long Distance
(USLD). These companies charge higher rates than AT&T operator-assisted
rates plus a high surcharge for the call itself. Hence these companies have
gotten a bad name for ripping off customers.
COCOTS are required by the FCC to let the customer access the carrier of
their own choice, usually by the Equal Access codes (101-xxxxx) or by the
rarely used 950 codes, or by toll-free (800/888/877/866) numbers. Many
COCOTs are not properly programmed for the 101-xxxxx codes. Be careful when
you use these phones if you want to use a carrier that is not the COCOT's
carrier (AOS or regular) that the phone will let you complete the call via
the carrier of your choice. Best bet is to use the toll-free number supplied
by your long distance company (ex: AT&T's 1-800-CALL-ATT)
