Indicating Fax over IP Capability in the Session Initiation Protocol

Overview

RFC 6913, “Indicating Fax over IP Capability in the Session Initiation Protocol”, is a Proposed Standard document published in March 2013 by D. Hanes, G. Salgueiro, K. Fleming. The canonical text is published by the RFC Editor.

Abstract

This document defines and registers with IANA the new "fax" media feature tag for use with the Session Initiation Protocol (SIP). Currently, fax calls are indistinguishable from voice calls at call initiation. Consequently, fax calls can be routed to SIP user agents that are not fax capable. A "fax" media feature tag implemented in conjunction with caller preferences allows for more accurate fax call routing.

What “Proposed Standard” means
