300-820 Exam Dumps : Implementing Cisco Collaboration Hybrid and Cloud Technologies

ICE controls the bandwidth usage for Cisco Collaboration endpoints if the endpoints are located outside the company network.

ICE enables Cisco Collaboration endpoints to determine if there is direct connectivity between them.

ICE uses FAST updates to optimize the video quality in case of packet loss. This technology is available only from Cisco Unified CM version 11.5 and later.

ICE enablement allows for the Cisco Collaboration endpoint to register through Expressway servers to Cisco Unified Communications Manager behind a firewall.

Expressway-C establishes an outgoing request to Expressway-E, enabling the Expressway-E in the DMZ to notify the internal Expressway-C of an incoming call from an external endpoint.

Internal endpoints are registered to Expressway-E in the DMZ. Expressway-C, which is also in the DMZ, will receive and make calls on behalf of Expressway-E because they are in the same network.
