ABSTRACT:
A wireless telephone system comprises a base unit and a plurality of wireless handsets. The base unit has a base transceiver and a memory for storing stored information. Each handset has a handset transceiver for establishing a data link and an audio link with the base unit via the base transceiver, wherein the data link is for transmitting signaling information and the audio link is for transmitting voice data for a real-time telephone call. The handset requests from the base unit certain stored information. In response, the base unit retrieves the requested stored information from the memory and transmits the stored information to the handset via the audio link.
