We have some problems with dtmf detection on our lines. We use E1 pris
connected to a TE405P. Mostly we see duplicated digits. Unless the signal 
is perfect and distortion free Asterisk sees the small imperfections as 
the end of the digit.

We can provoke this problem from some of our office phones (when on 
speaker phone). Asterisk is more or less the only place we see this 
problem.
