Abstract
Although the SIP History-Info header is the solution adopted in IETF,the non-standard Diversion header is nevertheless widely implementedand used for conveying call-diversion-related information in SIPsignaling.
This document describes a recommended interworking guideline betweenthe Diversion header and the History-Info header to handle calldiversion information. In addition, an interworking policy isproposed to manage the headers' coexistence. The History-Info headeris described in RFC 4244 and the non-standard Diversion header isdescribed, as Historic, in RFC 5806.
Since the Diversion header is used in many existing networkimplementations for the transport of call diversion information, itsinterworking with the SIP History-Info standardized solution isneeded. This work is intended to enable the migration from non-standard implementations and deployment toward IETF specification-based implementations and deployment. This document is not an Internet Standards Track specification; it is published for informational purposes.
