[Problems to be solved by the invention]

The conventional private branch telephone exchange is configured as described above.When the other party is busy, you can camp on the other party's telephone number and wait until the other party becomes empty, but only one destination at a time. There is a drawback that you can connect only when you and the other party are empty because you can only register only.

Therefore, when making a phone call with different departments such as sales, materials, and inspection one after another, if there are many calls, redialing is often repeated, which is inconvenient.

The present invention has been made to eliminate the above-mentioned drawbacks of the conventional ones, and an object of the present invention is to provide a private branch telephone exchange capable of registering a plurality of destinations, thereby reducing the number of dials and waiting time. I am trying.

[Means for solving problems]

The private branch telephone exchange according to the present invention is capable of so-called camp-on operation in which a plurality of telephones are accommodated, and an empty one of a plurality of telephones registered by the caller is connected to the calling telephone. The exchange comprises: destination dial storage means for storing a plurality of partner telephone numbers dialed after the special dial number; and call dial storage means for storing the number of the telephone that has called the special dial number. When any one of the destination telephones corresponding to the telephone number stored in the destination dial storage means becomes empty, the destination telephone and the calling telephone are connected.

[Action]

In the present invention, the registration of the second and subsequent partner telephones as the target of the camp-on operation is performed using the telephone number itself as in the first dialed partner telephone, so that the number of dials and waiting time can be reduced. Alternatively, the second and subsequent telephone sets that the caller can register as the target of the camp-on operation can be any telephone set other than the calling side connected to the exchange.
