[Freeswitch-users] Digium TDM410 + DTMF + echo cancel

I am having a continuing problem with freeswitch and the Digium TDM 
card.  For some period of time after a reboot, DTMF is detected 
correctly for incoming calls, and there is no problem with echo. All is 

Then at some point, dtmf is no longer detected on incoming calls handled 
by the TDM card.  Presumably at the same time that dtmf quits being 
detected, the echo cancellation quits working.  Again, just on incoming 
calls handled by the Digium card.  The only way I've been able to get 
things working again is to reboot the server, but it doesn't seem to 
last for long.

Can anyone suggest how I might track down what is wrong?
