asterisk users - Jan 2006 - Reading sound and recognizing DTMF sounds in eagi script ?

Hi,

we've connected Sphinx4 through eagi script (modified eagi example) to
Asterisk. Users can now say their wishes - but for gradual evolution we
would like also to provide "older" way of DTMF navigation too - can we
recognize
DTMF while reading sound in eagi ?

Any advice or examples ?

Thanks in advance,

regards,

Rob.
