    The callee’s machine was successfully contacted but the user
    explicitly does not wish to or cannot participate. The response MAY
    indicate a better time to call in the Retry-After header field. This
    status response is returned only if the client knows that no other
    end point will answer the request.

    Collect a SIP trace and see if a reason is supplied.
