ABSTRACT:
A communication device comprises a first transmitter configured to transmit a telephone signal via a broadband-communication link to an IP network, and a second transmitter configured to transmit a telephone signal via an alternative communication link to a telephone network. The telephone signal is transferred from a first telephone number for identifying the communication device in the transmission of the telephone signal via the broadband-communication link to a second telephone number associated with the alternative communication link when a power failure occurs during a transmission of the telephone signal via the broadband-communication link.
