This configuration is not supported on ERE and is intended for use only with an external PSX.
The SBC supports a flexible policy mechanism to facilitate dynamic routing and policy decisions based on any SIP message information element whereby routing and policy selection criteria are provisioned by the operator. An information element can be anything in the message, such as the following examples:
The flexible policy process is summarized below:
The SBC supports creating a SIP adaptor profile designated for the flexible policy mechanism. This
flexiblePolicyAdapterProfile profile is provisioned and attached to either/both the ingress Trunk Group or Ingress Zone. If
flexiblePolicyAdapterProfile is provisioned both at the trunk group and zone, the trunk group’s profile takes precedence. If
inputAdapterProfile is configured, it is applied first to manipulate the PDU and then
flexiblePolicyAdapterProfile rules are applied on the manipulated PDU.
For CLI or EMA configuration details, refer to:
The SBC applies flexible policy rules on received SIP messages to store information in variables. These variables are then passed to PSX over the
Diameter+ interface in a policy request message.
The PSX uses the received information contained in these variables as a part of its enhanced Routing and Policy decision making. Refer to PSX documentation for additional details.
