Note

Use the same configuration on all SBCs that communicate to a particular SLB.


SLB Deployment with the D-SBC and IMS LI

Use the following example to deploy the SLB for both Egress and Ingress interception.

Egress and Ingress Interception


Note

This deployment is applicable for both the D-SBC and I-SBC.

Ingress Interception

The ingress interception occurs if User1 is the target and a call originated from User1.

In this case, the DSR message uses the SSPIngress port of SLB instead of the local port of the SBC.


Egress Interception

The egress interception occurs if User2 is the target and a call is terminated to User2.

In this case, the DSR message uses the SSPEgress port of the SLB instead of the local port of the SBC.
