Abstract

PURPOSE:To simplify an operation for convocation of a conference by calling the conference participators through the speaker paging and making them attend the conference in response to the answers of the called subscribers. CONSTITUTION:When a subscriber A who convokes a conference performs the speaker paging through a route of a subscriber circuit LCA an NW a speaker paging conference trunk (SPK-PG-CFT) a speaker device in order to call the conference participators. When a subscriber has a hooking operation, a switch SW is actuated to switch the paging channel to the one for conference. While a called subscriber gives an answer by dialing a special number after having an off-hook operation. Thus the subscriber is successively connected to the corresponding terminals of the trunk (SPK-PG-CFT), and the channel is extended for the conference purpose (up to a contact of b-n). Thus a connection path is completed for the conference.

The speaker paging service, which calls a called party who is away from the telephone using the speaker, and the conference service, which allows two or more subscribers to make a call at the same time, exist separately, and are provided as separate services. It is in operation.

議を招集する人にとって操作が繁雑であった。Because conference services require multiple subscribers to hold conferences simultaneously using telephones, conference convenors have used a method of calling 91 conference participants one by one by hooking or the like. That is, the conference convenor first dials and calls the first conference participant, then hooks after entering the call state, dials and calls the second conference participant, and calls the called party (the second conference participant). If the participant (participant) answers, a three-way call can be made. By repeating this operation, conference participants up to the maximum number allowed by the system are called, and when a plurality of subscribers are simultaneously in a talking state, a conference can be held. As described above, the conventional conference system is complicated to operate for the person convening the conference.
