System and method of establishing a telephone connection

摘要

A system and method of establishing a telephone connection between an A-subscriber device and a B-subscriber device in a telephone system is disclosed. The method involves receiving a first approval signal from a first approval device before establishing the telephone connection. The first approval signal signals the approval of a user of the A-subscriber device to establish the telephone connection with the B-subscriber device. Also, a second approval signal is received from a second approval device before establishing the telephone connection. The second approval signal signals the approval of a user of the B-subscriber device to establish the telephone connection with the A-subscriber device. In the proposed method, the telephone connection is established between the A-subscriber device and the B-subscriber device only after receiving the first approval signal and the second approval signal.
