Although the use of the Reason header field in responses is
considered in general in RFC3326, its use is not specified for any
particular response code. Nonetheless, 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
gatewayed to PSTN systems. This document specifies and formally
permits the use of the Reason header field in SIP responses to carry
Q.850 reason codes for this and other purposes.
