ABSTRACT:
A wireless local area network (WLAN) transceiving integrated circuit services voice communications in a WLAN with at least one other WLAN device and includes a WLAN interface, a transcoder, and a switch box. The WLAN interface wirelessly communicates with at least one WLAN device to receive inbound packetized audio data from the at least one WLAN device and to transmit outbound packetized audio data to the at least one WLAN device. The transcoder receives the inbound packetized audio data and converts the inbound packetized audio data to inbound Pulse Code Modulated (PCM) WLAN audio data. The WLAN interface also receives outbound PCM WLAN audio data and converts the outbound PCM WLAN audio data to the outbound packetized audio data. The switch box operably couples between the transcoder and a PCM bus, to which an audio COder/DECoder (CODEC) couples. A speaker and a microphone coupled to the audio CODEC. The switch box enables the WLAN transceiving integrated circuit to perform call conferencing operations, call forwarding operations, call hold operations, call muting operations, and call waiting operations.
