2. Introduction
This Phone is an advanced phone that allows users to achieve perfect voice communication over
the IP network without using a personal computer. Not only does the Phone support all the
conveniences and functions of a digital key system phone, it also perfectly integrates all the merits
and features of analog and IP phones over the data communication system. As voice signals are
automatically compressed using audio CODECs, they can be transmitted over a low bandwidth
without interference from other data signals. Furthermore, to provide consistent superior voice
quality over varying and congested IP network conditions, the Phone is equipped with advanced
Quality of Service (QoS) technologies such as CODEC negotiation, enhanced jittering technology,
lost packet reconstruction, echo cancellation, and packet delay recovery.
