  I don't know what "the SRV in the proxy1_address" means but you're
spot on with the call flow.  It tests exactly as you and Cisco say.

  I want to use an outbound proxy for a couple of reasons.  One is to
get a reasonable set of call logs and the second is that the ACL set
on the gateway requires transit through a known gateway.  Neither is a
killer objection.  Billing might rear its ugly head someday, but not so
far.

  Obviously, I'm not sure of the intended use of outbound proxy :)  It
doesn't seem to be what it appeared to me.  Thanks, and thanks Steve as
well.
