Pekka,

Thank you.  This was a source of some confusion as we began testing in more
varying network configurations.

One more follow-on question:  Should outbound invites contain a Request-URI
and From-Header of the form: "sip:[EMAIL PROTECTED]" or "sip:[EMAIL PROTECTED]"?

Best Regards,
Jerry

Basically, outbound proxy serves outbound calls, the inbound calls are
handled by proxy, that gets your current contact from location service,
which is updated by registrar. Your UA talks directly to registrar and
outbound proxy only.

Usually the registrar/location service/proxy is co-located, they run on a
single server and they usually are a single piece of software, too.
(Location service can use external DB.)
