ABSTRACT:
A conferencing method for a telephone switch system for performing a conferencing function. In addition to a simple conferencing function, if there is a call request from a new subscriber, a conferencing function subscriber makes the existing subscriber wait, and communicates with the new subscriber or selects to communicate with the existing subscriber. Also, if it is desired to delete a specific subscriber, the specific subscriber can be deleted during conferencing communication, using a deletion key and a deletion code. If it is intended to delete some subscribers and add some subscriber during the conferencing communication, deletion and addition can be simultaneously performed, thereby achieving various conferencing services.
