About This Guide
Thank you for choosing the Yealink VC110 full HD video conferencing endpoint. It is an
all-in-one unit that supports 1080P-full HD video conferencing and includes outstanding
features such as good compatibility, easy deployment and intelligent network adaptability.
These make it the best choice for SME.
The Yealink VC110 full-HD video conferencing endpoint is designed to help enterprises
organize video conferences easily and efficiently. Users can expect to enjoy the high-quality
video conferencing experience very cost-effectively.
The guide is intended for administrators who need to configure, customize, manage, and
troubleshoot the video conferencing endpoint properly, rather than for end-users. It provides
details on the functionality and configuration of the Yealink VC110 video conferencing
endpoint.
Many of the features described in this guide involve network and account settings, which could
affect the endpoint’s performance in the network. Therefore, an understanding of IP networking
and a prior knowledge of VoIP telephony concepts are necessary.
See the Yealink Products Regulatory Notices Guide for all regulatory and safety guidance.

VC110 Video Conferencing Endpoint Introduction

VC110 Video Conferencing Endpoint
Introduction
This chapter contains the following information about VC110 video conferencing endpoint:
VoIP Principles
Physical Features of Endpoint
Packaging Contents
Endpoint Component Instructions
Icon Instructions
LED Instructions
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.

Administrator’s Guide for Yealink VC110 Video Conferencing Endpoint

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 endpoints. 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 to be carried across network boundaries. Session management provides the ability
to control the attributes of an end-to-end call.
Physical Features of Endpoint
Video conferencing endpoints are in the overall network topology, which are designed to
interoperate with other compatible equipment, including application servers, media servers,
Internet-working gateways, and other endpoints.
In order to operate endpoints in your network successfully, the endpoints must meet the
following requirements:
A working IP network is established.
VoIP gateway is configured for SIP or H.323, and H.323 gatekeeper is configured for H.323.
You can also deploy Cloud server for Cloud platform.
The latest (or compatible) firmware of endpoint is available.
A call server is active and configured to receive and send SIP/H.323 messages.
