Hello alain,

DTMF decoders are very hard to find. I know there are many models on the market but they seem to be unavailable.

Clare, Motorola, SDI, TI and some others manufacturers have stated the end of manufacture for this part!

Zarlink are another company that make this part, but they are not interested to sell it for an order under 10000 units.

I think a function like DTMF Decoding would be very interesting in the next release of PBP.

salut!
Martin
