The
platform platform supports inter-working between
the Diversion header and
the History-Info header based on RFC 6044. In addition to handling the History-Info header in SIP messages in the dotted notation of indexes, the
supports the SBC supports the Cause parameter
as specified in RFC 4458 or
the Reason
header as specified header specified in RFC 4244.
The IP Signaling Profile flag, "Diversion History Info Interworking," , indicates to the egress side that the inter-working is accomplished as per the RFC 6044. In addition, the existing Redirecting Info flag of "Diversion" and "History-Info" will indicate to the egress of the target inter-working header, which needs to be sent out in the INVITE message. The Diversion and History-Info headers received on the ingress side are transparently passed across to the egress, where newly introduced flags determine the corresponding header to be used to pass on this information in information in outgoing INVITE.
This feature is supported across GW-GW, where the is the egress node.

---|
When a 3xx response is received with both Diversion and History-Info header, Diversion header processing is given priority within the received 3xx, irrespective of the Diversion or History-Info configuration on the new egress route where the call is redirected. |

Diversion History Info Interworking | Enable flag to allow interworking between Diversion and History-Info header as per RFC 6044. The supports up to 12 History-Info entries and 10 Diversion entries. When this flag is disabled, only the first and last entries are maintained when History-Info or diversion transparency is disabled. |

Diversion History Info Interworking
This flag is only visible when either the Diversion or History-Info header is selected as the egress call-forwarding header. When it is enabled, the Diversion and History-Info Transparency configuration |
controls are ignored when it is enabledcontrols are ignored. This parameter has precedence over |
the othersthese controls and the TG Signaling flag Accept History Info. |
Data Mapping | Use this parameter to define how to map the diversion or redirecting data. Options are: |
none
– - None – No Diversion information is egressed.
|
diversion
- Diversion – Diversion information is sent out as SIP Diversion Header.
- pkHeaders – Diversion information is sent out as proprietary PK Headers.
|
Diversion Header Transparency | When enabled, the ingress Diversion header is passed through unchanged. Call forwarding data mapping transparency applies to the Diversion header only. |
