2. Description of the Related Art Conventionally, a method disclosed in Japanese Patent Application Laid-Open No. 1-220948 is known as a method for holding and holding a call in which a call that has already been put on hold is placed in a call while the call is in progress. This method is a three-way call by pressing the conference button and the line button on hold during a call,
By pressing one of the line buttons during a call in a three-way call state, a two-way call is made with the other party corresponding to the button and the other is put on hold.

[0003]

However, the above-described conventional hold-in / pull-in system has a problem in that it is not possible to make a two-party call between the hold party and the other party who are withdrawn from the state in which the call is in progress. Also, when pulling in the hold person, pressing the line button on hold will immediately make a three-way call, so if you accidentally pull in another hold person, the confidentiality of the conversation cannot be protected. There is a problem.

The present invention solves the above-mentioned conventional problems, and provides a hold pull-in method that enables confirmation of a person to be held before answering when a call that is already on hold is pulled in from a call state to make a call. The purpose is to provide.

[0005]

In order to achieve the above object, the present invention is to hold a call partner by pressing a transfer button and a holding button during a call, and to hold the call partner on the pressed button. The two-way call was made, and by the operator's on-hook, the call that was previously in progress and the held call that was pulled in were made into a two-way call.

Further, according to the present invention, by pressing the display button and the on-hold button, the information of the other party on hold is displayed on the display of the multi-function telephone and the on-hold response is made by pressing the pull-in button. did.

[0007]

With the above configuration, by pressing the transfer button and the hold button during a call, the other party in the call is put on hold, and the two-way call with the call that was held by the push button is made.
You can verbally confirm the other party, and you can avoid making a three-way call by pulling in the wrong party.

Further, by pressing the display button and the on-hold button, it is possible to confirm the on-hold party on the button and prevent the wrong person from being drawn.
