Kim, the ericsson 101 008 chip does support voice and the required headset protocol. It has a PCM input/output/sync/clk on pins A1-A4.

It just requires geting the PCM output from the Bluetooth module 'into' the empeg's board. and the same to get a PCM stream off the board from the empeg's Mic sampler, to the input of the Bluetooth module.

Then you could use the UART interface of the bluetooth module to control the phone like you are currently doing, but with the added functionality of a voice-recognition handsfree kit.

The only problem I can see is getting the PCM signal on/off the empeg's board.

Any Ideas?
Oli.
