1. A telephone for use with a first network having a predetermined allocated bandwidth and a second network having a variable bandwidth, the telephone comprising:

  • an interface circuit that selectively couples to the first and second networks, the first and second networks operating substantially independent of one another;

    a user interface;

    processing circuitry, coupled to the user interface and the interface circuit, that directs the interface circuit to select one of the first and second networks;

    a microphone capable of being selectively coupled to the first and second networks via the interface circuit; and

    an analog to digital converter that is coupled by the interface circuit between the microphone and the second network under the control of the processing circuitry when the second network is selected;

    wherein the processing circuitry responds to the user interface to determine which of the first and second networks to select.
