Before You Configure

Before you configure realms, you want to establish the phy and network interfaces with which the realm will be associated.

• Configure a phy-interface to define the physical characteristics of the signaling line.
• Configure a network-interface to define the network in which this realm is participating and optionally to create VLANs.

If you wish to use QoS, you should also determine if your Oracle® Enterprise Session Border Controller is QoS enabled.

Remember that you will also use this realm in other configurations to accomplish the following:

• Set a signaling port or ports at which the Oracle® Enterprise Session Border Controller listens for signaling messages.
• Configure sessions agents to point to ingress and egress signaling devices located in this realm in order to apply constraint for admission control.
• Configure session agents for defining trusted sources for accepting signaling messages.
