Although the use of the SIP (Session Initiation Protocol) Reason
header field in responses is considered in general in RFC 3326, its
use is not specified for any particular response code.  Nonetheless,
existing deployments have been using Reason header fields to carry
failure-related Q.850 cause codes in SIP responses to INVITE requests
that have been gatewayed to Public Switched Telephone Network (PSTN)
systems.  This document normatively describes the use of the Reason
header field in carrying Q.850 cause codes in SIP responses.
