No; the Contact header has to have something valid.

However, you could place a URI in there that routes to the user through
a proxy, but this has to be done CAREFULLY to guarantee that the request
won't fork and will always reach the right UA. This is really not the
recommended approach. If you want to be reached through a proxy, having
the proxy record route is the correct approach.
