This thread was covered ad nauseam some time ago.  Try my code posted at

ftp://ftp.ormix.riga.lv/mchip/sources/dtmf_dec.zip
ftp://ftp.ormix.riga.lv/mchip/sources/dtmf_cod.zip

if it still exists.  If it doesn't, then mail me direct and I'll send
you a copy.  dtmf_cod (generating DTMF) works, but dtmf_dec (decoding)
would require a little work to make it robust, and it also assumes an
external ADC.
