An intercept message is a telephone

The telephone , colloquially referred to as a phone, is a telecommunications device that transmits and receives sounds, usually the human voice. Telephones are a point-to-point communication system whose most basic function is to allow two people separated by large distances to talk to each other...

 recording informing the caller that the call cannot be completed, for any of a number of reasons ranging from local congestion, to disconnection of the dialled phone, or network trouble along the route.

The precise wording of intercept messages is left to the discretion of each local telephone company, except that most such messages nowadays start with one of several Special information tones, standardized by Telcordia when it was still called Bellcore.

In the 1970s, for example, New York Telephone

 used the following:
"I'm sorry; the number you have reached is not in service, or temporarily disconnected. The number you have reached is not in service at this time. This is a recording."


In rural areas, the name of the town from which the exchange service is furnished was often included in the message; this was especially true if the telephone company providing the service was not part of the Bell System
Bell System
The Bell System was the American Bell Telephone Company and then, subsequently, AT&T led system which provided telephone services to much of the United States and Canada from 1877 to 1984, at various times as a monopoly. In 1984, the company was broken up into separate companies, by a U.S...

 today. It reads as follows:
"We're sorry; you have reached a number that has been disconnected or is no longer in service. If you feel you have reached this recording in error, please check the number and try your call again."


The option also exists to replace the generic message with a customized message, as applicable, such as in cases where a subscriber's telephone number has changed, most commonly due to relocation; in that instance, the disconnected number

 would be repeated, followed by a recitation of the new number. In many localities — particularly in or near large cities — this option is used even in cases where no new number has replaced the old one.

In the past, the call would be forwarded to an intercept operator after usually two readings of the message; today, however, this procedure is not observed, and a busy signal follows the second reading of the message instead.

A different intercept message is used when the caller has dialed a number the first three digits of which have not yet been assigned within that area code. This message, too, formerly varied by locality; the following was used in New York City

 in the 1960s:
"If you are calling a number outside New York City, please dial the area code and the local number. If you are dialing a New York City number, please check the number and dial again. This is a recording. If you need assistance, please call your operator."


The standard version of this message in use today is the following:
"We're sorry; we are unable to complete your call as dialed. Please check the number and dial again, or call your operator to help you."

There is also a network message heard when an attempt to route a call to a nodal or ISDN T1 on the terminating end fails due to no call set-up signal from the PBX being received by the far-end Tandem or edge switch " Your call did not go through, 9142T".

The first automatic intercept systems used rotating magnetic drums containing multiple recorded phrases, with a computer
