CHAPTER 26 SBC Manipulations
Configure stricter classification rules higher up in the table than less strict rules to
ensure the desired rule is used to manipulate the incoming dialog. Strict refers to the
number of matching characteristics configured for the rule. For example, a rule
configured with source host name and source IP Group as matching characteristics is
stricter than a rule configured with only source host name. If the rule configured with
only source host name appears higher up in the table, the device ("erroneously") uses
the rule to manipulate incoming dialogs matching this source host name (even if they
also match the rule appearing lower down in the table configured with the source IP
Group as well).
To configure and apply an Inbound Manipulation rule, the rule must be associated with a Routing
Policy. The Routing Policy associates the rule with an SRD(s). Therefore, the Routing Policy lets
you configure manipulation rules for calls belonging to specific SRD (s). However, as multiple
Routing Policies are relevant only for multi-tenant deployments (if needed), for most deployments,
only a single Routing Policy is required. As the device provides a default Routing Policy ("Default_
SBCRoutingPolicy"), when only one Routing Policy is required, the device automatically assigns
the default Routing Policy to the routing rule. If you are implementing LDAP-based routing (with or
without Call Setup Rules) and/or Least Cost Routing (LCR), you need to configure these settings
for the Routing Policy (regardless of the number of Routing Policies employed). For more
information on Routing Policies, see
The IP Groups table can be used to configure a host name that overwrites the received
host name. This manipulation can be done for source and destination IP Groups (see
Configuring IP
The following procedure describes how to configure Inbound Manipulation rules through the Web
interface. You can also configure it through ini file [IPInboundManipulation] or CLI (configure
voip > sbc manipulation ip-inbound-manipulation).

To configure an Inbound Manipulation rule:
1. Open the Inbound Manipulations table (Setup menu > Signaling & Media tab > SBC folder >
Manipulation > Inbound Manipulations).
2. Click New; the following dialog box appears:
