In X, the service access number (AN number) and the user identification number (UID number) determined by the caller's extension terminal device are used as the other party's dial number sent from the extension for an outside call from the extension. It is disclosed that an extension terminal device of a caller can be specified by additionally providing a function of transmitting to the public telephone network and notifying the service management equipment attached to the public telephone network of the UID number. . Also, the extension caller is "0" + "AN number" +
There is disclosed a technique or the like in which the UID number is notified to the service management facility attached to the public telephone network by collectively inputting “UID number” + “*” + “dial number”. Here, "0" is an outside line calling number.

[0005]

However, in the above-mentioned conventional technique, "0" + "partner dial number" required for calling the partner terminal of the outside line from the extension and the extension terminal device of the caller are specified. In addition to the "UID number" necessary for the service, an "AN number" for accessing the service management facility and identification information "*" for distinguishing the "UID number" from the "dial number of the other party" are required. There was the problem of requiring special procedures.

Further, there is a problem that only a code consisting of numerical information from 0 to 9 can be used as the UID number.

The object of the present invention is to eliminate the above-mentioned problems of the prior art, and without the need for a special procedure, ISD.
