Hi,

The difference between the request and response(s) between CLIENT 1 and the SIP SERVER
is that in the response message angle quotes have been added around the URI in the To-
and From headers.

Now, there has been a discussion if that's allowed or not (it's a little unclear in
bis), but I think the decission was that it IS allowed (since the angle quotes are not
used for URL comparision etc), so CLIENT 1 SHALL be able to handle it.
