+1.  Introduction
+
+   This document creates an IANA registry for the response codes for the
+   MEDIACTRL Interactive Voice Response Control Package [RFC6231].
+
+2.  Security Considerations
+
+   There are no security considerations, other than those described in
+   the MEDIACTRL Interactive Voice Response Control Package [RFC6231].
+
+3.  IANA Considerations
+
+   IANA has created the "MEDIACTRL Interactive Voice Response Control
+   Package Status Codes" registry per this document.  New status codes
+   are assigned using the Standards Action process defined in RFC 5226
+   [RFC5226].
