Calling Line Identification for Voice Mail Messages
RFC 3939, “Calling Line Identification for Voice Mail Messages”, is a Proposed Standard document published in December 2004 by G. Parsons, J. Maruszak. The canonical text is published by the RFC Editor.
Abstract
This document describes a method for identifying the originating calling party in the headers of a stored voice mail message. Two new header fields are defined for this purpose: Caller_ID and Called_Name. Caller_id is used to store sufficient information for the recipient to callback, or reply to, the sender of the message. Caller-name provides the name of the person sending the message. [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.
