[Sip] RequestUri to Host Matching and proxy servers

["Jean-Francois Mule" <jf.mule@cablelabs.com>]

Updating the sip mib ID with Kevin & Kavitha, we have a quick question
re: Request-URI and host matching for proxy servers.  Is there any
application where not requiring request-uri host matching makes sense
for a proxy?
We thought about the outbound proxy case where requests are usually
targetted for external proxies, therefore request-uri to host matching
may potentially not be the default action.

We have a sipRequestUriHostMatching mib object (true/false value) that
is currently applicable to UAs and proxies and we're wondering whether
to keep it as a common configuration object or move it to the UA config
section of the mib.

Additionally, if request-URI to host matching is enforced, is it ok for
the object description to state something like:
"If the value of this object is 'true', then the server requires a
match, and if the RequestURI doesn't match the server's host name, a
Location Service may be used to obtain information about a callee's
possible location(s) or a 404 Not Found status code is returned by the
server."

Thanks,
Jean-Francois.
