My users here have complained about similar problems. We've noticed it
most often on outside callers with cell phones, but one user brought in
a phone from home that pretty consistently would mess up. I hooked it up
to an inside line and it still happens. My guess is that asterisk is
being a little to stringent with it's DTMF detection. Looking at the log
asterisk will detect multiple DTMF events for a single key press. I
looked at a recording of the tone and it looked a bit different than a
phone that generated 'good' tones 100% of the time, but it certainly
wasn't sending a tone and stopping.
