Cisco VCS Administrator Guide (X7.2)
Definition
A VCS with the same functionality as a VCS Control that can also act as a firewall
traversal server. This is generally located outside the firewall.
A technology that reduces the negative effects of packet loss on networks without QoS.
A text-based user interface used to access the VCS.
A collection of between two and six VCSs that have been configured to work together
as a single Local Zone, in order to provide scalability and redundancy.
An application that allows the VCS to support the Multiway feature. See the
Conference Factory section for more information.
An XML-based language for defining call handling. Defined by
A list from a CA (certificate authority) of previously signed certificates that it marks as
no longer valid.
A subzone used to represent locally registered endpoints and systems that do not fall
within any other existing configured subzones within the Local Zone.
A pre-configured zone on the VCS used to represent incoming connections from
endpoints that are not recognized as belonging to the Local Zone or any of the existing
configured neighbor, traversal client or traversal server zones.
An option key that allows VCS to provision endpoints with configuration information on
request and to supply endpoints with phone book information. See the
Provisioning section for more information.
A Quality of Service (QoS) mechanism supported by the VCS.
A distributed database linking domain names to IP addresses.
On the VCS, a zone used to configure access to endpoints located via a DNS lookup.
An ITU standard for structured telephone numbers. Each telephone number consists of
a country code, area code and subscriber number.
A means of mapping E.164 numbers to URIs using DNS. Defined by
On the VCS, a zone used to enable 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.
