Title : Mapping and interworking of Diversion information Between Diversion and History-Info Headers in the Session Initiation Protocol (SIP)

Abstract:
Although the SIP History-Info header field is the solution adopted in
IETF, the non-standard Diversion header field is nevertheless already
implemented and used for conveying call diversion related information
in the Session Initiation Protocol (SIP) signaling.
On one hand, the non-standard Diversion header field is described, as
Historic, in [RFC5806]. On the other hand, the History-Info header
field is described in [RFC7044] that obsoletes the original[RFC4244]
describing the History-Info header field. [RFC7044] defines the SIP
header field, History-Info, for capturing the history information in
requests and new SIP header field parameters for the History-Info and
Contact header fields to tag the method by which the target of a
request is determined. [RFC7044] also defines a value for the
Privacy header field that directs the anonymization of values in the
History-Info header field.
Since the Diversion header field is used in existing network
implementations for the transport of call diversion information, its
interworking with the SIP History-Info standardized solution is
needed. This document describes a recommended interworking guideline
between the Diversion header field and the History-Info header field
to handle call diversion information. In addition, an interworking
policy is proposed to manage the headers' coexistence. This work is
intended to enable the migration from non-standard implementations
and deployments toward IETF specification-based implementations and
deployments.
This document obsoletes [RFC6044]that describes the interworking
between the Diversion header field [RFC5806] and the obsoleted
History-Info header field as defined on [RFC4244].
