What channel driver? I once documented a repeatable problem with IAX and
IAX2 where it quit responding to the first DTMF and would sometimes have
trouble passing audio back after 2 minutes. Our temporary solution at
the time was to modify the record function to pass silent audio frames
back. Of course we later just abandoned long IAX recordings so we could
stay in sync with the CVS tree.
