Standards
E.164
An ITU-T (International Telecommunication Union) E series recommendation,
representing a numbering plan for international electronic communications. An
E.164 number uniquely identifies a public network termination point and typically
consists of three fields, CC (country code), NDC (national destination code), and
SN (subscriber number), up to 15 digits in total. This can be thought of as a Service
number.
H.323
An ITU-T “umbrella” of standards for Packet-based multimedia communications
systems. This standard defines the different multimedia entities that make up a
multimedia system - Endpoints, Gateways, Multipoint Conferencing Units
(MCUs), and Gatekeepers -- and their interaction over an IP-based network.
H.323 Alias
An identifier (name) for a terminal, User or Meeting using H.323 protocol. When
conducting video conferencing using H.323 protocol, values identifying terminals,
users or Meetings are assigned. However, these values are extremely difficult for
humans to remember so a separate name (alias) represented by a character string is
also assigned. This can be thought of as a Service number.
ITU-T (International Telecommunication Union Telecommunication
Standardization Sector)
A sub-organization of the International Telecommunication Union (ITU), serving
as the standardization sector for electronic communications. It is the development
body for international standards related to telecommunications.
