Session Initiation Protocol (SIP) Back-to-Back User Agents (B2BUAs)
are often designed to be on the media path rather than just
intercepting signaling.  This means that B2BUAs often act on the
media path leading to separate media legs that the B2BUA correlates
and bridges together.  When acting on the media path, B2BUAs are
likely to receive Session Traversal Utilities for NAT (STUN) packets
as part of Interactive Connectivity Establishment (ICE) processing.

This document defines behavior for a B2BUA performing ICE processing.
The goal of this document is to ensure that B2BUAs properly handle
SIP messages that carry ICE semantics in Session Description Protocol
(SDP) and STUN messages received as part of the ICE procedures for
NAT and Firewall traversal of multimedia sessions.

This document is a product of the Sip Traversal Required for Applications to Work Working Group of the IETF.

This is now a Proposed Standard.

STANDARDS TRACK: This document specifies an Internet Standards Track
protocol for the Internet community, and requests discussion and suggestions
for improvements.  Please refer to the current edition of the Official
Internet Protocol Standards (https://www.rfc-editor.org/standards) for the 
standardization state and status of this protocol.  Distribution of this 
memo is unlimited.
