Another node in the cluster is used and an intra-cluster cascade between Webex and the new Video Mesh node is formed.

When Expressway Core works with VMN clusters, Expressway Core decides which VMN is used for signaling/media connection.

Cloud-registered devices choose a VMN cluster based on the lowest STUN round trip delay.

The cascading traffic between VMN must bypass the firewall.

When Cisco Unified Communications Manager works with multiple VMNs, Cisco Unified CM decides which VMN is used for signaling connection.

A VMN can terminate a media connection while operating in maintenance mode.

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.
