OK, so is there a way to have hardware echo canceling and have DTMF
digits go out correctly?  We bought the expensive hardware echo
canceling card however it appears that we have to have vpmsupport=0
in order to get DNIS digits correctly (see my thread about ADIT and
DNIS digits earlier).  Clarifications about what to tweak appreciated.

Thanks,
William.
