About This Guide
Yealink administrator guide is intended for administrators who need to properly configure,
customize, manage, and troubleshoot the IP phone system rather than end-users. This guide
will help you understand the Voice over Internet Protocol (VoIP) network and Session Initiation
Protocol (SIP) components, and provides descriptions of all available phone features.
This guide describes three methods for configuring IP phones: central provisioning, web user
interface and phone user interface. It will help you perform the following tasks:
Configure your IP phone on a provisioning server
Configure your phone’s features and functions via web/phone user interface
Troubleshoot some common phone issues
Many of the features described in this guide involve network settings, which could affect the IP
phone’s performance in the network. So an understanding of IP networking and a prior
knowledge of IP telephony concepts are necessary.
The information detailed in this guide is applicable to firmware version 81 or higher. The
firmware format is like x.x.x.x.rom. The second x from left must be greater than or equal to 81
(e.g., the firmware version of SIP-T46G IP phone: 28.81.0.20.rom).
See the
Yealink Products Regulatory Notices guide
for all regulatory and safety guidance.
