DTMF issue

Hi All…

I am using Asterisk 1.6 and zaptel 1.4.9.2 with Digiums TE412p card.
I have E1 pri’s terminated on the box.

I have a strange problem dettecting the DTMF for calls coming from some of the operators. i noticed this problem mostly from calls coming from long distance.

bellow is content of my zapata.conf.

You can add “toneduration=300”, probably get function correct.
