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.
