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.
