   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.
