Remote Survivable Call Process Behavior

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

1. Phones register directly on remote site E-SBC.
2. Phone-to-phone calls are proxied directly on remote site E-SBC.
3. Phone-to-PSTN calls are routed by remote site E-SBC to local PSTN gateway.
