FYI, and this may not be relevant because of the
vintage however you should check the results on the
particular versions you are running in production
because it obviously varies by version. I would have
expected the results that Ryan outlined however when I
just tested this in the lab with (CM3.3(4) SRST 3.1)
the phone reset and registered with SRST using the
phones default profile as I remember it doing. I'm
guessing that this is either a bug in the versions I'm
running or maintaining the logged in profile was added
in newer releases?
