A config param for dtmf lenght is not yet present.
I saw that this problem (when it happens) goes away if you lower the volume of the capture device, at the mixer level (alsamixer in linux) or at the celliax level (capture_boost in celliax.conf).
It is incredible how much low you can set the volume and still have celliax working, btw.

Can you please report if this works for you?
Bye for now,
