About This Guide

end-users of the IP phones. It provides details on the functionality and configuration of
the IP phones.
Many of the features are described in this guide involving the network settings, which
could affect the IP phone’s performance in the network. So an understanding of IP
networking and prior knowledge of IP telephony concepts are necessary.

the SIP-T3xG IP phones are available:
Quick Installation Guides, which describe how to assemble the IP phones.

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

describes how to configure the BroadSoft features on the BroadWorks web portal
and the IP phones.
