No, that is not normal. The UAS (the server receiving the initial 
INVITE) is required to copy the Record-Route into dialog-forming responses.

 From RFC 3261 Section 12.1.1 ("UAS Behavior"):

    When a UAS responds to a request with a response that
    establishes a dialog (such as a 2xx to INVITE), the UAS
    MUST copy all Record-Route header field values from the
    request into the response (including the URIs, URI
    parameters, and any Record-Route header field parameters,
    whether they are known or unknown to the UAS) and MUST
    maintain the order of those values.
