It is a bit sad that the special extensions live in the same namespace
as normal extensions. The reasons are historical, of course, from when
Asterisk was mostly concerned with connecting to the PSTN, but these
days it is becoming a problem.

I am not sure what to do about it though. A start would be to forbid
patterns from matching the special extensions, so that you could use
_h to match h exactly, without matching hangup.

Another nice thing would be to get rid of some of the reasons why
people use e.g. h. My favourite would be to always record HANGUPCAUSE
in the CDR's, without having to use exten =>
