PROBLEM TO BE SOLVED: To instantly open a conference speech anytime and anywhere in the case of introducing this communication conference system to a conference communication equipment provided especially with a PHS by allowing all the slave set selecting the same conference speech number to receive a slave set call originating number concerning all the slave set call origination signal selecting the same conference speech number. SOLUTION: The group of slave sets is divided into job groups A and B, e.g. At first, slave sets 1 to 3 make a job group A where the three person can simultaneously call-originate a speech and receive it by inputting the same conference number X. On the other hand, slave sets 4 and 5 makes a job group B where the three person can simultaneously call-originate a speech and receive it by inputting the same conference number Y. In addition the integrated group of the groups A and B, etc., can be organized by allowing the slave set 1 to 5 to previously set the speech combination of X and Y by a master set 9. At the same time of changing the form of a job like this, the slave sets 1 to 5 optionally change the conference speech number. |
