Do you mean, only one originating caller has problems with DTMF, but
other callers do not?
What kind of phone/service are they calling from?
We have had problems specifically with Skype/Skypeout customers not
working correctly with DTMF. I have heard of others who have problems
with certain cell phones calling their Asterisk box, and failing to do
DTMF correctly.
