TELEPHONE SWITCHING SYSTEM, TELEPHONE SWITCHING APPARATUS, METHOD, AND NON-TRANSITORY COMPUTER READABLE MEDIUM ON WHICH PROGRAM HAS BEEN STORED

WIPO Patent Application WO/2018/179525

A1

A transmission reservation is made by providing notification of the terminal information of a mobile terminal via the Internet. Concurrently, the notification of the terminal information of the mobile terminal is provided to a telephone switching apparatus of the company via a telephone network. The telephone switching apparatus checks the terminal information of the transmission-source mobile terminal having made the transmission reservation via the Internet against the transmission-source terminal information received via the telephone network, and, in the case of a successful authentication, calls up the reserved transmission-destination terminal with the switching apparatus of the company serving as the transmission source. In this way, when a telephone call is made from the mobile terminal of a user to a customer, the number of the personal mobile terminal is not displayed on the transmission-destination terminal. Moreover, there is no need to perform a complicated operation using a call back, so that the communication charge to be borne by the company can be reduced.
