User's Manual 37. Routing SBC

Instead of using tags and configuring the parameter, you can use the
'Destination Username Prefix' parameter to specify a specific URI
destination user or all destinations users.
Message Condition
message-condition-name
[IP2IPRouting_MessageC
onditionName]
Assigns a SIP Message Condition rule to the IP-to-IP Routing rule.
To configure Message Condition rules, see Configuring Message
Condition Rules on page 387.
Call Trigger
trigger
[IP2IPRouting_Trigger]
Defines the reason (i.e., trigger) for re-routing (i.e., alternative routing)
the SIP request.

[0] Any = (Default) This routing rule is used for all scenarios (re-
routes and non-re-routes).

[1] 3xx = Re-routes the request if it was triggered as a result of a SIP
3xx response.

[2] REFER = Re-routes the INVITE if it was triggered as a result of a
REFER request.

[3] 3xx or REFER = Applies to options [1] and [2].

[4] Initial only = This routing rule is used for regular requests that the
device forwards to the destination. This rule is not used for re-routing
of requests triggered by the receipt of REFER or 3xx.

[5] Broken Connection = If the device detects a broken RTP
connection during the call and the Broken RTP Connection feature is
enabled (IpProfile_DisconnectOnBrokenConnection parameter is
configured to [2]), you can use this option as an explicit matching
characteristics to route the call to an alternative destination.
Therefore, for alternative routing upon broken RTP detection,
position the routing rule configured with this option above the regular
routing rule associated with the call. Such a configuration setup
ensures that the device uses this alternative routing rule only when
RTP broken connection is detected.

[6] Fax Rerouting = Reroutes the INVITE to a fax destination
(different IP Group) if it is identified as a fax call. For more
information, see Configuring Rerouting of Calls to Fax Destinations
on page 684.
ReRoute IP Group
re-route-ip-group-id
[IP2IPRouting_ReRouteIP
GroupName]
Defines the IP Group that initiated (sent) the SIP redirect response
(e.g., 3xx) or REFER message. This parameter is typically used for
rerouting requests (e.g., INVITEs) when interworking is required for SIP
3xx redirect responses or REFER messages. For more information, see
Interworking SIP 3xx Redirect Responses on page 644 and
Interworking SIP REFER Messages on page 647, respectively. The
parameter functions together with the 'Call Trigger' parameter (in the
table).
The default is Any (i.e., any IP Group).
Note: The selectable IP Group for the parameter depends on the
assigned Routing Policy (in the 'Routing Policy' parameter in this table).
For more information, see Configuring SBC Routing Policy Rules on
page 692.
