Agreed.  But before getting started with Asterisk, I posted a similar idea
to the group; it was met with a quite cool reception, on and off-list.  See
http://lists.digium.com/pipermail/asterisk-users/2004-October/068932.html .
I ended up avoiding Vonage and using multiple other providers.

That said, I believe that many users of non-BYOD ITSPs would benefit from
a proxy such as you describe.  Unfortunately, I'm not aware of anyone
that has implemented it yet.  If you undertake such a project, IMO you
should do it in Asterisk, or as a separate process that can run on the
same machine as Asterisk, because many more people would use it and
contribute to its development.
