A New Internet-Draft is available from the on-line Internet-Drafts 
directories.
This draft is a work item of the Session Initiation Proposal Investigation Working Group of the IETF.

	Title		: Requirements from SIP (Session Initiation Protocol) Session Border Control Deployments
	Author(s)	: J. Hautakorpi, et al.
	Filename	: draft-ietf-sipping-sbc-funcs-03.txt

This document describes functions implemented in Session Initiation
   Protocol (SIP) intermediaries known as Session Border Controllers
   (SBCs).  The goal of this document is to describe the commonly
   provided functions of SBCs.  A special focus is given to those
   practices that are viewed to be in conflict with SIP architectural
   principles.  This document also explores the underlying requirements
   of network operators that have led to the use of these functions and
   practices in order to identify protocol requirements and determine
   whether those requirements are satisfied by existing specifications
   or additional standards work is required.

NOTE:	The mail server at ietf.org can return the document in
	MIME-encoded form by using the "mpack" utility.  To use this
	feature, insert the command "ENCODING mime" before the "FILE"
	command.  To decode the response(s), you will need "munpack" or
	a MIME-compliant mail reader.  Different MIME-compliant mail readers
	exhibit different behavior, especially when dealing with
	"multipart" MIME messages (i.e. documents which have been split
	up into multiple messages), so check your local documentation on
	how to manipulate these messages.

Below is the data which will enable a MIME compliant mail reader
implementation to automatically retrieve the ASCII version of the
Internet-Draft.
