CHAPTER 25 Routing SBC
■ If the Routing Policy is assigned to only one SRD and the SRD is an Isolated SRD, the routing
rules of the Routing Policy can be configured with IP Groups belonging to the Isolated SRD
and IP Groups belonging to all Shared SRDs.
■ If the Routing Policy is assigned to a Shared SRD, the routing rules of the Routing Policy can
be configured with any IP Group (i.e., belonging to Shared and Isolated SRDs). In effect, the
Routing Policy can include routing rules for call routing between Isolated SRDs.
■ If the Routing Policy is assigned to multiple SRDs (Shared and/or Isolated), the routing rules of
the Routing Policy can be configured with IP Groups belonging to all Shared SRDs as well as
IP Groups belonging to Isolated SRDs that are assigned the Routing Policy.
To facilitate the configuration of routing rules in the IP- to- IP Routing table through the Web
interface, only the permitted IP Groups (according to the above) are displayed as optional values.
The general flow for processing the call for multi-tenant deployments and Routing Policies is as
follows:
1. Using the Classification table, the device classifies the incoming call to an IP Group, based on
the SIP Interface on which the call is received. Based on the SIP Interface, the device
associates the call to the SRD that is assigned to the SIP Interface.
2. Once the call has been successfully classified to an IP Group, the Routing Policy assigned to
the associated SRD is used. However, if a Routing Policy is configured in the Classification
table, it overrides the Routing Policy assigned to the SRD.
3. The regular manipulation (inbound and outbound) and routing processes are done according to
the associated Routing Policy.

The following procedure describes how to configure Routing Policies rules through the Web
interface. You can also configure it through ini file [SBCRoutingPolicy] or CLI (configure voip
> sbc routing sbc-routing-policy).
➢
To configure a Routing Policy rule:
1. Open the Routing Policies table (Setup menu > Signaling & Media tab > SBC folder >
Routing > Routing Policies).
2. Click New; the following dialog box appears:
The Classification table is used only if classification by registered user in the
device's users registration database or by Proxy Set fails.
If the device receives incoming calls (e.g., INVITE) from users that have already
been classified and registered in the device's registration database, the device
ignores the Classification table and uses the Routing Policy that was determined
for the user during the initial classification process.
