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.

This is now a Proposed Standard.
