Abstract

PURPOSE:To answer an incoming call by dialing only the extension number of the extension being receiving the incoming call for the incoming call to an extension belonging to the same already-known call pickup group. CONSTITUTION:When a call is made from an extension A4 to that C6, a central control equipment 2 sets the memory of an extension status storage 3 corresponding to the extension number of the extension C6 busy. Later, if the extension number of the extension C6 is dialed at the extension B5, the central controller 2 read out the memory in the storage 3, and decides the extension C6 to be receiving an incoming call, subsequently, the equipment 2 read a memory in a extension number storage 7 by group, and decides the extension C6 and B5 to be registered as belonging to the same call pickup group. Thereafter, the central control equipment 2, depending on such two decision-results that the two are busy with each other and that they are the extensions belonging to the same call pickup group, lets the extension C6 to stop ringing, and connects the extension B5 and that A4. Accordingly, the incoming call can be answered.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a designated extension call pickup method for a storage program controlled automatic switching system, and more particularly to a designated extension call pickup method when answering an incoming call.

[Conventional technology]

The traditional designated extension call pickup method, when an extension answers an incoming call to an extension that belongs to the same call pickup group as the extension, dials the designated extension call pickup number and the extension number of the extension receiving the incoming call. This allows the incoming call to be answered.

[Problem that the invention seeks to solve]

The conventional designated extension call pickup method described above has the disadvantage that when answering an incoming call, it is cumbersome to dial both the designated extension call pickup number and the extension number of the extension receiving the incoming call.

[Means for solving problems]

The designated extension call pickup method of the present invention has a storage device that stores the extension numbers of extensions belonging to a call pickup group and the incoming call status for each extension, and a control device that controls this storage device, and When answering an incoming call to an extension belonging to a pickup group, the incoming call can be answered by dialing only the extension number of the extension receiving the incoming call.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

FIG. 1 is a block diagram of an embodiment of the invention. In FIG. 1, ■ is a call path switch, ■ is a central control unit, ■ is an extension status storage device, ■ is an extension A, ■ is an extension B, ■ is an extension C1, and ■ is a group-specific extension number storage device. here,
When extension C■ is called from extension A■, the central controller ■ sets the memory of the extension status storage device ■ corresponding to the extension number of extension C■ as "incoming call." After that, extension B■
When the extension number of extension C■ is dialed from , the central controller ■ reads the memory in the extension status storage device ■ and determines that extension C■ is receiving a call. Subsequently, the central control device (2) reads the memory in the group-by-group extension number storage device (2) and determines that extension C (2) and extension B (2) are registered to belong to the same call pickup group. After that, the central controller (■) determines that extension C is incoming and belongs to the same call pickup group as described above.
The ring tone of ■ is stopped, and extension B■ and extension A■ are connected. If extension C■ is empty, extension B■ becomes extension C.
When the extension number (2) is dialed, the call is received at extension C (2), and then, in response to a response from extension C (2), extension B (2) and extension C (2) are connected. Additionally, if extension C■ and extension B■ are not registered to belong to the same call pickup group, if extension B dials the extension number of extension C■ while extension C■ is receiving a call, extension B A busy tone is sent to ■.

〔Effect of the invention〕

As explained above, the present invention answers an incoming call to an extension belonging to the same known call pickup group by dialing only the extension number of the extension receiving the incoming call. This makes it possible to connect to the calling party's extension, thereby eliminating the hassle of dialing a designated extension call pickup number.
