Interworking SIP Diversion and History-Info Headers
This device can be configured to interwork between the SIP Diversion and History-Info headers.
This is important, for example, to networks that support the Diversion header but not the History-
Info header, or vice versa. Therefore, mapping between these headers is crucial for preserving the
information in the SIP dialog regarding how and why (e.g., call redirection) the call arrived at a
certain SIP UA. If the Diversion header is used, you can specify the URI type (e.g., "tel:") to use in
the header, using the SBCDiversionUriType parameter.
This feature is configured in the IP Profiles table using the following parameters:
■
'Diversion Header Mode' (IPProfile_SBCDiversionMode) - defines the device's handling of the
Diversion header
■
'History-Info Header Mode' (IPProfile_SBCHistoryInfoMode - defines the device’s handling of
the History-Info header
The handling of the SIP Diversion and History-Info headers is described in the table below:
