Abstract

This document focuses on use cases and call flows which include the History-Info header field and a SIP Identity header field with a PASSport with a "div" claim in cases of retargeting. These use cases are derived from those provided in the SIP History-Info call flows document. The objective is to describe the optimal way to correlate the History-Info header fields with a PASSporT with diversion information to increase the level of confidence in the History-Info header field by the terminating entity making use of the information.
