Alias
The name an endpoint uses when registering with the VCS. Other endpoints can then use this name to call it. An endpoint may register with more than one alias.
Alternate
One or more VCSs configured to support the same zone in order to provide redundancy. See also Cluster.
AOR
A SIP or SIPS URI that points to a domain with a location service that can map the URI to another URI where the user might be available. Typically, the location
Address of Record
service is populated through registrations. An AOR is frequently thought of as the "public address" of the user.

An endpoint RAS request to make or answer a call.
Admission Request

TANDBERG's proprietary protocol for firewall traversal.

A TANDBERG device used to control multimedia networks and firewall traversal.

a given criteria. (Also referred to as Administrator Policy.)
CLI
A text-based user interface used to access the VCS.
Command line interface
Cluster
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.
Conference Factory
An application that allows the VCS to support TANDBERG's Multiway feature. 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
CPL
An XML-based language for defining call handling. Defined by
Call Processing Language
Default Subzone
A subzone used to represent locally registered endpoints and systems that do not fall within any other existing configured subzones within the Local Zone.
Default Zone
A configurable zone on the VCS used to represent incoming connections from endpoints that are not recognized as belonging to any of the existing configured

Device Provisioning
An option key that can be installed on the VCS that enables the TMS Agent feature. See the
DNS
A distributed database linking domain names to IP addresses.
Domain Name System
DNS zone

E.164

European Headquarters' phone number is +47 67 125125, corresponding to a country code of 47 for Norway, area code of 67 for Lysaker and finally 125125 to
determine which phone line in Lysaker.
