1.  Introduction

The SIP Forum User Agent Configuration Recommendation (Lawrence, S., Ed., “User Agent Configuration Recommendation,” December 2009.) [SFUACFG] defines a procedure for SIP [RFC3261] (Rosenberg, J., Schulzrinne, H., Camarillo, G., Johnston, A., Peterson, J., Sparks, R., Handley, M., and E. Schooler, “SIP: Session Initiation Protocol,” June 2002.) User Agents to

  1. determine the SIP domain from which to request configuration,
  2. locate one or more server(s) that provide the configuration service for that domain,
  3. construct a URL for and request configuration from that service,
  4. request that the service send notices of any changes to that configuration.

The second step, locating the configuration service for a given domain, is achieved by the U-NAPTR (URI-Enabled NAPTR) application defined in [RFC4848] (Daigle, L., “Domain-Based Application Service Location Using URIs and the Dynamic Delegation Discovery Service (DDDS),” April 2007.), which builds upon the S-NAPTR (Simple NAPTR) application defined in [RFC3958] (Daigle, L. and A. Newton, “Domain-Based Application Service Location Using SRV RRs and the Dynamic Delegation Discovery Service (DDDS),” January 2005.).

This document registers the application service tag "SFUACFG" for this operation, as required by the U-NAPTR application.
