1. A method of integrating a digital encoded-audio bit stream player in a radio-frequency (RF) telephone handset, comprising:

  • establishing an RF connection between the RF telephone handset and an RF unit connected to a network, wherein communications between the RF telephone handset and the network pass through the RF unit;

    switching the RF telephone handset from performing as a telephony device to performing as a digital encoded-audio bit stream player;

    playing digital encoded-audio bit stream music from the RF telephone handset;

    muting the digital encoded-audio bit stream music playing from the digital encoded-audio bit stream player when the RF telephone handset receives a telephone call; and

    switching the RF telephone handset from performing as a digital encoded-audio bit stream player to performing as a telephony device while the telephone call is active, wherein;

    (i) the RF telephone handset comprises;
