Automatic control of connection to subscriber of a telephone center involves connecting caller to subscriber despite access being closed or informing caller that subscriber's telephone is off

摘要

The method involves the center either connecting the caller to the subscriber despite access being closed, or informing the caller that the subscriber's telephone is switched off, if the center receives a defined signal, e.g. a defined key stroke sequence from the telephone, while sending information or during a defined period after sending information.
