	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.
