Video Conferencing Glossary

E.164

E.164 is an ITU-T recommendation which defines the international public telecommunication numbering plan used in the PSTN and some other data networks. In the Easymeeting network E.164 is used to provide EasyNumber to any registered endpoint.

EasyConference

EasyConference is our cloud service that allows you to connect into the same virtual meeting using video conferencing systems, computers, tablets and smartphones.

EasyNumber

With an EasyNumber you can reach anyone in the world and easily access other Easymeeting services such as the EasyConference (virtual meeting rooms) and more. To utilize EasyNumbers, your hardware must be connected with one of the Easymeeting gatekeepers (see gatekeeper below).

EMSAP (easymeeting services access point)

This is normally a gatekeeper or a traversal service.

FIREWALL

A firewall is a part of a computer network that is designed to block unauthorized access while permitting authorized communications.

GATEKEEPER

H.323 endpoints are not required to register with a gatekeeper to be able to place point to point calls, but they are essential for the Easymeeting experience. The gatekeeper handles address translation, which allows users to make calls with an EasyNumber instead of hard to remember IP addresses that also may change each day.

GUI (graphical user interface)

This term is reffering to the graphical user interface on your system. Usually managed by the remote control for your equipment.

H.323

This is a recommendation from the ITU Telecommunication Standardization Sector (ITU-T) that defines the protocols to provide audio-visual communication sessions on any packet network. The H.323 standard addresses call signaling and control, multimedia transport and control, and bandwidth control for point-to-point and multi-point conferences.

H.323 Name / H.323 Extension

The H.323 is provided by Easymeeting service center and is required to authenticate your system with EMSAP in order to connect to Easymeeting and dial an EasyNumber.

H.460

This is a series of extensions to the H.323 videoconferencing standard. It contains several extensions and is designed to deal with firewall and NAT traversal. For example, they enable end points to communicate with each other without the need of intermediate nodes. Also see traversal.

TCP / UDP

The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) are the two core protocols of the Internet Protocol Suite used for data communication. TCP and UDP provide the service of exchanging data between two different network hosts.

TRAVERSAL

Traversing is a method for communication between network units behind a NAT or firewall to receive incoming data over TCP or UDP connections where the firewall normally blocks traffic. H.460 is the common traversing method designed for videoconferencing traffic.

WEB-UI (web user interface)

You can use the web user interface to perform most of the calling and configuration tasks you can perform on the local system.
