This draft is a work item of the Basic Level of Interoperability for SIP Services Working Group of the IETF.

	Title           : Basic Level of Interoperability for Session Initiation Protocol (SIP) Services (BLISS) Problem Statement

The Session Initiation Protocol (SIP) has been designed as a general
purpose protocol for establishing and managing multimedia sessions.
It provides many core functions and extensions in support of features
such as transferring of calls, parking calls, and so on.  However,
interoperability of more advanced features between different vendors
has been poor.  This document describes the reason behind these
interoperability problems, and presents a framework for addressing
them.

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.
