Active Alarms
ICE Connection Type Indicates the type of connection between the Collaboration Server and the
participant in the ICE environment:
• Local (or Host) - The endpoint (Remote) is on the same network as the
Collaboration Server and the media connection is direct, using local
addresses.
• Relay - Media between the Collaboration Server and the participant passes
through a media relay server.
• Firewall - Media connection between the Collaboration Server and the
participant is done using their external IP addresses (the IP addresses as
seen outside of the local network).
