Abstract
An apparatus and structure for transmitting and receiving an audio signal over a network (25). A dual mode telephone (1) is adapted to switch between a standard telephone mode and an Internet Protocol (IP) telephone mode. The standard telephone mode comprises a standard telephone (11) adapted to transmit and receive audio over a standard telephone network (37). The IP telephone mode comprises an IP telephone (15) adapted to convert an audio signal to an IP packet and transmit the IP packet over a communication link (14) to a network (25).
Claims22
A dual mode telephone, comprising:
- a telephone adapted to switch between a standard telephone mode and an Internet Protocol (IP) telephone mode, the telephone operating in the standard telephone mode as a standard telephone that is adapted to transmit and receive an audio signal over a standard telephone network, and the telephone operating in the IP telephone mode as an IP telephone that is adapted to convert the audio signal to an IP packet and transmit the IP packet over a network, the telephone further adapted to:
- in response to detecting the standard telephone network, switch to the standard telephone mode and transmit the audio signal over the standard telephone network;
- in response to detecting the network, switch to the IP telephone mode;
- in response to a telephone number being inputted while the telephone is operating in the IP telephone mode, convert the telephone number to an IP address, convert the audio signal to the IP packet and transmit the IP packet over the network to a second standard telephone;
- and
- in response to an IP address being inputted while the telephone is operating in the IP telephone mode, convert the audio signal to the IP packet and transmit the IP packet over the network, wherein the telephone determines whether the IP packet is transmitted over the network to one of a second dual mode telephone and a computing device.
