Remote Survivable Call Process Behavior

The following illustration shows the remote survivable call process behavior of the ROBO Oracle® Enterprise Session Border Controller when connectivity fails to the Service Provider site (or headquarters site).

1. Phones register directly on remote site Oracle® Enterprise Session Border Controller.
2. Phone-to-phone calls are proxied directly on remote site Net-Net ESD.
3. Phone-to-PSTN calls are routed by remote site Oracle® Enterprise Session Border Controller to local PSTN gateway.
