Yealink SIP-T27P [5/841] Documentations

About This Guide

This guide is intended for administrators who need to properly configure, customize,

manage, and troubleshoot the IP phone system rather than end-users. It provides

details on the functionality and configuration of IP phones.

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.

SIP-T21(P) E2 and SIP-T19(P) E2 IP phones. The following related documents are

available:

 Quick Start Guides, which describe how to assemble IP phones and configure the

most basic features available on IP phones.

 User Guides, which describe the basic and advanced features available on IP

phones.

 Auto Provisioning Guide, which describes how to provision IP phones using the
