Internet Engineering Task Force SIP WG Internet Draft G. Camarillo Ericsson draft-camarillo-sip-uri-parameter-reg-00.txt June 17, 2003 Expires: December 2003 The Internet Assigned Number Authority Universal Resource Identifier Parameter Registry for the Session Initiation Protocol STATUS OF THIS MEMO This document is an Internet-Draft and is in full conformance with all provisions of Section 10 of RFC2026. Internet-Drafts are working documents of the Internet Engineering Task Force (IETF), its areas, and its working groups. Note that other groups may also distribute working documents as Internet- Drafts. Internet-Drafts are draft documents valid for a maximum of six months and may be updated, replaced, or obsoleted by other documents at any time. It is inappropriate to use Internet-Drafts as reference material or to cite them other than as "work in progress". The list of current Internet-Drafts can be accessed at http://www.ietf.org/ietf/1id-abstracts.txt To view the list Internet-Draft Shadow Directories, see http://www.ietf.org/shadow.html. Abstract This document creates an IANA registry for SIP URI and SIPS URI parameters. It also lists the already existing parameters to be used as initial values for that registry. G.

Camarillo [Page 2] Internet Draft SIP June 17, 2003 1 Introduction RFC3261 [1] allows new SIP URI and SIPS URI parameters to be defined. However, RFC3261 omitted an IANA registry for them. This document creates such a registry. 2 Use of the Registry Both RFC defined and proprietary SIP URI and SIPS URI parameters MUST be registered with IANA as described below. 3 IANA Considerations Section 27 of RFC 3261 [1] creates an IANA registry for method names, header field names, warning codes, status codes, and option tags. This specification instructs the IANA to create a new sub-registry under http://www.iana.org/assignments/sip-parameters: o SIP/SIPS URI Parameters 3.1 SIP and SIPS URI Parameters Sub-Registry New SIP and SIPS URI parameters are registered by the IANA. When registering a new SIP or SIPS parameter, the following information MUST be provided. o Name of the parameter. o For proprietary parameters, a brief description of its semantics. o A reference to a further description, if available. For example, (in order of preference) an RFC, a published paper, a patent filing, a technical report, documented source code or a computer manual. o For proprietary parameters, contact information (postal and email address). Table 1 contains the initial values for this sub-registry. 4 Security Considerations There are no security considerations associated to this document. G.
