A record A type of DNS record that maps a d omain name to an IPv4 address.
AAAA record A type of DNS record that maps a d omain name to an IPv6 addre ss.
Administrator Policy In relation to the VCS, the set of rules c onfigured system-wi de (either via the web interfa ce or CPL script) that determin e the action(s) to be applied to calls matc hing
a given criteria.
Alias The name an endpoint uses when re gistering with the VCS. Othe r endpoints can then use this na me to call it.
Alternate One or more VCSs configured to sup port the same zone in orde r to provide redundancy.
ARQ
Admission Request
An endpoint RAS request to make o r answer a call.
Assent TANDBERG’s proprietary protoc ol for firewall traversal.
Border Controller A TANDBERG device used to control mul timedia networks and fire wall traversal.
Call Policy The set of rules (administrator poli cy, user policy and transforms) that a re applied to a single call to deter mine whether and how it is placed .
CLI
Command Line Interface
A text-based user interf ace used to access the VCS.
CPL
Call Processing Language
An XML-based language for defi ning call handling. Defined b y RFC 3880 [5].
DNS
Domain Name System
A distributed database linkin g domain names to IP addresse s.
DNS zone On the VCS, a zone used to c onfigure access to endpoi nts located via a DNS lookup.
E.164 An ITU standard for stru ctured telephone number s. Each telephone number co nsists of a country code, area c ode and subscriber number. For ex ample, TANDBERG’s
European Headquarters’ p hone number is +47 67 125125, correspondi ng to a country code of 47 for Nor way, area code of 67 for Lysaker and finally 125125 to

Gatekeeper A devic e used to control H.323 multimedi a networks. An example is the TANDB ERG Gatekeeper.
Gatekeeper Zone A collection of all the endpoints, gateways an d MCUs managed by a single gatekeep er.
H.323 A stand ard that defines the proto cols used for packet-based m ultimedia communication s systems.
HTTP
Hypertext Transfer Protoco l
A protocol used for communicat ions over the internet.
HTTPS A protocol used f or secure communications ov er the internet, combining HT TP with TLS.
Hop count The number of times a location requ est may be forwarded to a gateke eper or proxy before it is dee med to have failed.
ICE
Interactive Connectivi ty Establishment
A collaborative algorithm th at works together with STUN ser vices (and other NAT traversal te chniques) to allow clients to achieve f irewall traversal.
