One or more Contact headers will be included in the 3xx response to tell the
UAC where to redirect the request to. If the server cannot determine where
to redirect the call to it would send back something like 404 or 480. The
redirect server could also reject the request for a variety of other
reasons. For example, it may require authentication and respond with 407.

Usually it would redirect all requests unless it could service or proxy the
request forward. Or it could reject the request. It depends on what the
redirect server is configured to do.
