Technical Summary
Currently, RFC3326 is non-specific as to the use of the
Reason header field in SIP responses. However, existing
deployments have been using Reason header fields in responses
to carry Q.850 reason codes for failure responses to INVITE
requests that have been sent via gateways to PSTN systems.
This document normatively describes the use of the Reason
header field in SIP responses to carry Q.850 reason codes.
