A mechanism we should also abandon ASAPractical. It would be just as
easy for sipXconfig to generate a voicemail alias for every user that
has voicemail. That alias would be the same as the contact the current
mappingrule constructs, but would be computed at configuration time
rather than every time someone makes a call. Doing so would have 3
advantages:
* It would remove the need for this confusing backwards usage of
the 'permission' elements (applying them to the target rather
than the caller); in this context, it would have been clearer to
call them 'capabilities' rather than 'permission's but the
original author wanted to use the same schema and parser for all
three *rules.xml files.
* Looking up an alias in the database is conceptually much simpler
and probably performs better than the current implementation of
the mappingrules interpreter (if not, we should definitely
replace fastdb). [Yes, I know I'm breaking my own rule about
unsubstantiated predictions about performance, but it's still
simpler.]
* It would allow us to smoothly support different voicemail
systems for different users (which doesn't really work right
now).
