[asterisk-dev] How to detect DTMF digits in channel driver

[Carlos Munoz]

I'm writing a new channel driver to interface to a board with 2 FXS 
ports. The hardware in these ports can't detect DTMF digits therefore 
the channel driver has to do it in software. I'm looking through the 
code to but I'm having a hard time getting it to work.

Does anyone have any ideas on how to do this or point me in the right 
direction ?
