Cisco VCS Administrator Guide (X7.1)
Definition
A protocol for accessing on-line directories running over TCP/IP.
In relation to the VCS, a connection between two nodes.
(Also referred to as a non-traversal call.) A call where the signaling but not the media
is routed through the local VCS. See the
information.
A relative term used to refer to any endpoint or system that is registered with the local
VCS.
A relative term used to refer to the particular VCS that you are currently administering,
as opposed to other VCSs in your network.
A relative term used to refer to the group of endpoints and other systems registered to
a particular VCS. If a VCS is part of a cluster, the Local Zone refers to the collection of
all endpoints and other systems registered to all peers in that cluster.
A RAS query between gatekeepers to determine the location of an endpoint.
A network device that allows multiple endpoints to participate in a video conference.
Microsoft OCS (Office Communications Server) 2007 / Lync Server 2010 is an
enterprise real-time communications server, providing the infrastructure to allow
instant messaging, presence, audio-video conferencing and web conferencing
functionality.
The client application released with Microsoft Office Communications Server (OCS).
The MOC client can be used for instant messaging, presence, voice and video calls
and ad hoc conferences.
Cisco TelePresence Multiway enables endpoint users to create a conference while in
a call even if their endpoint does not have this functionality built in. See the
Conference Factory section for more information.
A type of DNS record.
Also known as IP masquerading. Rewriting source and destination addresses as the
IP packet passes through the NAT device.
A remote system to which the VCS has a connection via a neighbor zone.
On the VCS, a zone used to configure a connection to a remote system with which the
local VCS has a non-traversal relationship.
In relation to the VCS, a node is one end of a link. A node can be a local subzone or a
zone.
(Also referred to as a local call.) A call where the signaling but not the media is routed
through the local VCS. See the
A protocol used for synchronizing clocks. Defined in
