RFC 3326 states following:
The Reason header field MAY appear in any request within a dialog, in any CANCEL request and in any response whose status code explicitly allows the presence of this header field. The syntax of the header field follows the standard SIP parameter syntax. Does it imply that 18x and 200 OK can also contain Reason header ? I have come across examples where "Reason" header is included in INVITE, CANCEL, BYE, 4xx responses but have not found any 1xx or 200 OK (for INVITE) containing "Reason" header ? Pl. clarify ?
