Technical Summary
This documents describes functions implemented in Session
Initiation Protocol (SIP) intermediaries known as Session

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.
