asterisk users - Sep 2004 - Sprint PCS -> Asterisk through Digium TDM400P

Does anyone have trouble with dialing in to an Asterisk Server and 
having the DTMF digits recognized?  We have some clients who are calling 
in with cell phones, notably those with SprintPCS service, who's DTMF is 
just never recognized.

I have tried relax_dtmf on and off, with no improvement.  My rxgain is 
currently set to 3.

Can anyone suggest possible solutions?

Incoming calls are coming through POTS lines connected to the server to 
TDM400P with FXO modules.

Thanks,

Al

Unfortunatly, I can't offer any suggestions to correct the issue, but I can 
add that I see this on my X100P as well. It does seem particularly bad with 
Sprint; I think they may have shorter tone lengths than we really need. 

The only thing that I've found so far is that my calls coming in via SIP and
IAX do not exhibit the problem, so I've transitioned the bulk of my incoming
traffic to those mechanisms -- may not be an option for you of course.
