You need to enable DTMF logging (logger.conf) and debug an incoming /
outgoing call.  However, if your DTMF works locally, with asterisk and
SIP phones, but does not with your provider.  Then I would suspect the
issue is with your ITSP, make sure your provider is not converting
out-of-band tones to inband, or something like that.
