[Serusers] Regisater request with Recorde Route Header........

Hello, As per RFC 3261 the Registrars must ignore Record-Route field in any incoming REGISTER request and should not include the same in the response. But I find SER implementations including the Record Route Field in the 200OK Response. Any advice or suggestion??
