I have another PBX running the same exact version of asterisk that's newer
that doesn't exhibit the same problem.
I'm wondering if it is a timing thing? The PBX with the issue seems to
respond slower to DTMF (Background() takes longer to get interrupted, etc..)
It is an older box so it is using res_timing_dahdi (dahdi_dummy) and the
newer box is using res_timing_timerfd.

Any suggestions would be welcome.
