[VoIP] Update your directory entries, please!

[John R. Covert]

If you've got something running on CNET, please update your
entries.  Every once in a while, I happen to notice a call that
comes through my switch and get curious about either its caller
id or what it's dialling via my gateways.

I'm not going to publicly "out" anyone, but I have noticed that
there is at least one working office code with some interesting
step-by-step office sounds (maybe just a recording, maybe not)
that isn't even on the list, and doesn't yet follow our convention
of putting an informational recording on -0001.  Peculiarly, in
the one office I'm thinking about, a call to that number is
_accepted_ but then somehow returns CHANUNAVAIL rather than
CONGESTION, which I find intriguing.
