[asterisk-users] Sangoma A200D and DTMF Detection

[Andres]

Does anybody else have issues with the Hardware Echo Canceller and DTMF 
detection on this card?  I installed an IVR system (no VoIP), and the 
Zap channel does not detect DTMF tones properly.   For example the user 
hits 123 and the systems sees 1123 or just 23.  Trying relaxdtmf yes/no 
does not help at all.  If we disable the Hardware Echo Canceller, DTMF 
will work perfectly 100% of the time. 

Does anybody else have a similar experience with this?

Thanks,
