Overview

The Avaya 3641/3645 IP Wireless Handset with SIP is a mobile handset that uses the
Avaya Aura™ SIP call server (sometimes referred to as the PBX) and the Local Area
Network (LAN) to connect to other telephones at your workplace and on the public
telephone system. The handset gives you the freedom to roam throughout the workplace
while providing all the features and functionality of a SIP desk phone.
The handsets will only work when they are within range of the wireless access points at
your facility; they are not cellular or satellite phones.
Note:
