VC800/VC500 Video Conferencing System Introduction
1
VC800/VC500 Video Conferencing System
Introduction
This chapter contains the following information about VC800/VC500 video conferencing system:
VoIP Principles
Physical Features of System
Comparing VC500 Models
User Interfaces
VoIP Principles
VoIP
VoIP (Voice over Internet Protocol) is a technology that uses the Internet Protocol instead of
traditional Public Switch Telephone Network (PSTN) technology for voice communications.
It is a family of technologies, methodologies, communication protocols, and transmission
techniques for the delivery of voice communications and multimedia sessions over IP networks.
The H.323 and Session Initiation Protocol (SIP) are two popular VoIP protocols that are found in
widespread implementation.
H.323
H.323 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.
It is widely implemented by voice and video conference equipment manufacturers, is used
within various Internet real-time applications, such as GnuGK and NetMeeting, and is widely
deployed by service providers and enterprises for both voice and video services over IP
networks.
SIP
SIP (Session Initiation Protocol) is the Internet Engineering Task Force’s (IETF’s) standard for
multimedia conferencing over IP. It is an ASCII-based, application-layer control protocol
(defined in RFC 3261) that can be used to establish, maintain, and terminate calls between two
or more systems. Like other VoIP protocols, SIP is designed to address the functions of signaling
and session management within a packet telephony network. Signaling allows call information

Administrator’s Guide for Yealink VC800&VC500 Video Conferencing System
2
to be carried across network boundaries. Session management provides the ability to control
the attributes of an end-to-end call.
Physical Features of System
Video conferencing systems are in the overall network topology, which are designed to
interoperate with other compatible equipment, including application servers, media servers,
Internet-working gateways, and remote systems.
In order to operate systems in your network successfully, the systems must meet the following
requirements:
A working IP network is established.
The latest (or compatible) firmware of system is available.
VoIP gateway is configured for SIP, or H.323 gatekeeper is configured for H.323, or Cloud
server is configured for Cloud platform.

If you purchase VC500 model, but you want to use the features supported by VC500 Pro model,
you can contact Yealink FAE for help.
User Interfaces
Three are two ways to customize the configurations of your system:
Web User Interface
Remote Control
The following describes how to configure the VC800/VC500 video conferencing system via the
two methods above.
Detailed operation steps will be introduced in the feature section.
Web User Interface
You can customize your system via web user interface. To access the web user interface, you
