Telephone conference main device with conference participant display function

摘要

PROBLEM TO BE SOLVED: To provide a technique of displaying information of a participant in a programmable key arranged in a terminal concerning a telephone conference main device for storing multiple extension terminals.SOLUTION: When a division-base programmable key allocation section 16 receives a predetermined event, a division list 170 and a key allocation list 180 are generated or updated, the allocation of one or more participants with respect to multiple programmable keys is changed, and also lamp displaying is performed by a main device control section 13 with respect to the multiple programmable keys. Thus, conference participants allocated to the respective programmable keys are visually displayed. Consequently, information of a lot of participants whose number is more than the number of the programmable keys arranged in a telephone set can be displayed in a telephone conference where multiple extension terminals and an outside line are participants. Then, even when the number of participants becomes equal to or more than a number estimated by a promotor due to the increase of participants during a conference, conference conversation without the shortage of the programmable keys and the deterioration of convenience can be provided.SELECTED DRAWING: Figure 1
