Rejecting Anonymous Requests in the Session Initiation Protocol
RFC 5079, “Rejecting Anonymous Requests in the Session Initiation Protocol”, is a Proposed Standard document published in December 2007 by J. Rosenberg. The canonical text is published by the RFC Editor.
Abstract
The Session Initiation Protocol (SIP) allows for users to make anonymous calls. However, users receiving such calls have the right to reject them because they are anonymous. SIP has no way to indicate to the caller that the reason for call rejection was that the call was anonymous. Such an indication is useful to allow the call to be retried without anonymity. This specification defines a new SIP response code for this purpose. [STANDARDS-TRACK]
What “Proposed Standard” means
An entry-level standards-track specification: stable, peer-reviewed and a solid basis for implementation, though it may still evolve before becoming an Internet Standard.
