Cisco VCS Administrator Guide (X6.1)
Definition
On the VCS, a zone used to configure access to endpoints located via
ENUM.
The remote system that is used to manage endpoints and network
infrastructure. The Cisco TelePresence Management Suite (TMS) is an
example of an external manager.
Any zone configured on the local VCS that connects out to a remote system
or the internet. Neighbor, traversal server, traversal client, ENUM and DNS
zones are all external zones.
The act of crossing a firewall or NAT device.
Cisco TelePresence FindMe is a User Policy feature that allows users to
have a single alias on which they can be reached regardless of the endpoints
they are currently using.
A domain name that specifies the node's position in the DNS tree absolutely,
uniquely identifying the system or device. Note that in order to use FQDNs
instead of IP addresses when configuring the VCS, you must have at least
one DNS server configured.
A device used to control H.323 multimedia networks. An example is the
TANDBERG Gatekeeper.
A collection of all the endpoints, gateways and MCUs managed by a single
gatekeeper.
A standard that defines the protocols used for packet-based multimedia
communications systems.
A protocol used for communications over the internet.
A protocol used for secure communications over the internet, combining
HTTP with TLS.
The maximum number of gatekeeper or SIP proxy devices (e.g. a VCS) that
a message may be forwarded through before it is decided that its intended
recipient is not reachable.
A collaborative algorithm that works together with STUN services (and other
NAT traversal techniques) to allow clients to achieve firewall traversal. This
is the emerging traversal standard for use by SIP endpoints (although it could
be used for other protocols).
An organization that defines (via documents such as RFCs) the protocol
standards and best practices relating to the design, use and management of
the internet.
Allowing H.323 systems to connect to SIP systems.
