Actually, the problem has gone away for us, probably after some upgrade. 
We are running a cvs head version from december. The phones that used to 
be problematic no longer are. 

The last time we seem to have seen that problem according to the logs was 
in september. After an upgrade there the problems went away. 

Asterisk does handle imperfect DTMF tones correctly for us on our pure TDM
setup. We use VoIP very little and only over a lightly loaded lan and have
not noted any problems there either.

Sorry about the false alarm.
