Class II—A media endpoint device. The class II endpoint devices
support the media stream capabilities and the capabilities of generic
endpoint devices.
•
Class III—A communication endpoint device. The class III endpoint
devices directly support end users of the IP communication system.
Providing all capabilities of generic and media endpoint devices,
Class III endpoint devices are used directly by end users.
