In a slightly more ideal world, asterisk could be told: reload sip
peer whatever, and would only update the changed values while
retaining MWI and qualify information etc.

In a more ideal world, asterisk would only cache stuff that isn't kept
in the database at all -- the stuff it needs for MWI and qualify etc.
That way everything would always be up-to-date, and MWI would still
work.

In an even more ideal world, asterisk would keep everything in the
database, including the stuff it needs for MWI etc. There are
performance reasons to not do that, of course. Perhaps they can be
overcome.

I hope those proposals are constructive. (The next objection is
"where's the patch", and I do apologise for not including one.)
