2.
The device replaces the Contact header value with the special prefix and database
key value as user part, and with the device's URL as host part (e.g., Contact:
<sip:Prefix_Key_User@SBC:5070;transport=udp>;q=0.5).
3.
The device sends this manipulated SIP 3xx response to the Far-End User (FEU).
4.
The FEU sends a new request with the Request-URI set to the value of the received
3xx response's Contact header (e.g., RequestURI:
sip:Prefix_Key_User@SBC:5070;transport=udp).
5.
Upon receipt of the new request from the FEU, the device replaces the Request-URI
with the new destination address (e.g., RequestURI:
sip:Prefix_User@IPPBX:5070;transport=tcp;param=a).
6.
The device removes the user prefix from the Request-URI, and then sends this
Request-URI to the new destination (e.g., RequestURI:
sip:User@IPPBX:5070;transport=tcp;param=a).
32.8.1.2 Local Handling of SIP 3xx
The device can handle SIP 3xx responses on behalf of the dialog-initiating UA and retry the
request (e.g., INVITE) using one or more alternative URIs included in the 3xx response.
The new request includes SIP headers from the initial request such as Diversion, History-
Info, P-Asserted-Id, and Priority. The source and destination URIs can be manipulated
using the regular manipulation mechanism.
The device sends the new request to the alternative destination according to the IP-to-IP
Routing table rules. (where the 'Call Trigger' field is set to
3xx
). It is also possible to specify
the IP Group that sent the 3xx request as matching criteria for the re-routing rule in this
table ('ReRoute IP Group ID' field).
32.8.2 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 (IPProfile parameter) using the following
parameters:
SBCDiversionMode - defines the device's handling of the Diversion header
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:
