Abstract

PURPOSE:To prevent the talking of an extension telephone set from being disturbed by a busy tone uselessly even when the extension telephone set receives an incoming call from an external line during the talking. CONSTITUTION:A control section 2 references a setting data in a memory 3 to discriminate whether or not a ring tone is raised with respect to an incoming call, and in the case of making ringing, the state of the relevant telephone set is discriminated by referencing a busy flag in a memory 3. When the discrimination of all telephone sets is finished, the control section 2 references a flag (RING) in the memory 3 to discriminate whether or not a telephone set rings a usual incoming call tone and terminates the processing when the telephone set making ringing exists. On the other hand, when a telephone set making usual ring tone is not in existence, an extension interface 7 is started to make ringing a busy tone to all relevant telephone sets based on a telephone set number saved in the memory 3.

[0012] In this embodiment, a busy ringtone is sounded for all telephones when all of the telephones with the normal incoming ringing designation are busy, but it is not possible to set the busy ringtone to sound beforehand. You can also set the busy ringtone to sound only on specific telephones. (Other Examples) In this example,
When a call is busy, if there is an extension that belongs to the same group that can normally receive a call, the busy call is not made.

When the outside line interface 5 detects that there is an incoming call on the outside line (1) of the outside lines 6 (step S11), the control unit 2 refers to the table shown in FIG. 4 stored in the memory 3. When a call is received on the outside line (1), it is determined whether or not the extension designated to ring is busy (steps S12 and S13). In the example shown in FIG. 4, extensions 1 and 2

As described above, according to this embodiment, when an extension in the same group is being called by a normal calling signal, the calling signal is not sent to the busy extension. That is, since the extensions of the same group are ringing as usual, the caller can know the incoming signal even if the busy ring tone does not sound. Furthermore,
Since no unnecessary busy ringtone sounds during a call, it is possible to prevent the call from being interrupted more than necessary.

[Effects of the Invention] As explained above, when an extension phone receives a call from an outside line while the extension phone is on a call, if there is another phone that has a normal ringtone, the busy ringtone will not sound. This has the effect that the call will not be unnecessarily interrupted by the busy ringtone.
