RFC 3550 - 15. IANA Considerations

  1. IANA Considerations

Additional RTCP packet types and SDES item types may be registered through the Internet Assigned Numbers Authority (IANA). Since these number spaces are small, allowing unconstrained registration of new values would not be prudent. To facilitate review of requests and to promote shared use of new types among multiple applications, requests for registration of new values must be documented in an RFC or other permanent and readily available reference such as the product of another cooperative standards body (e.g., ITU-T). Other requests may also be accepted, under the advice of a "designated expert."

(Contact the IANA for the contact information of the current expert.)

RTP profile specifications SHOULD register with IANA a name for the profile in the form "RTP/xxx", where xxx is a short abbreviation of the profile title. These names are for use by higher-level control protocols, such as the Session Description Protocol (SDP), RFC 2327 [15], to refer to transport methods.
