Hi Sathyan

Thank you for supplying that code. I've been away from my desk most of this weekend. I will look into the code in depth when I get back.

Are you attempting to decode DTMF signals using one of these?
DTMF Smart Home Remote Controller MT8870 Decoder Module for Arduino Relay Shield | eBay
The code looks similar, though they don't include the full example code on the listing.

Is the code doing anything at all? What kind of messages are you receiving?
