Technical Summary This document defines an extension to the Session Initiation Protocol providing a new response code that may be used to reject an anonymous request so that the requesting party can understand that the request was rejected because it was made anonymously and could reasonably be expected to succeed if retried without anonymity. Working Group Summary The requirement addressed by this document was identified by ETSI TISPAN. The SIPPING working group discussed the requirement and determined that a SIP extension would be required to address that requirement. The technique specified by this document was originally introduced in an individual document submitted by Jonathan Rosenberg and discussed in the SIP working group. The SIP working group rapidly achieved consensus on the approach and recommended establishing a working group milestone for this work. There was no controversy within the SIP working group on the direction of this work. Document Quality This is a very simple extension to the SIP protocol. It is expected to be widely implemented in SIP systems interacting with the switched telephone networks of the world. Since it addresses requirements from ETSI TISPAN, participants from that organization were asked to review the specification and reported that it is suitable for their needs. Personnel The document shepherd is Dean Willis. The responsible area director is Cullen Jennings. No IANA expert, MIB doctor, or other specialized contributor is required.
