hi all,

I am having 3 Xbee S2 Pro and through them I want to communicate Node A to Node C via Node B by a voice call mechanism and vice-versa.

How to convert analog voice signal into digital data packets and make them transfer ?

Please help me to implement such process.

You don’t. You would need to use an external processor such as a Pic or Arduino to do both the ADC and DAC conversions.
