Chapter 1 Introduction
Voice over IP (VoIP) uses the Internet Protocol (IP) to transmit voice as packets over an IP
network. Hence, VoIP can be achieved on any data network that uses the IP, like the Internet,
Intranets, and Local Area Networks (LAN). In VoIP, the voice signals are digitized, compressed,
and converted to IP packets. The compressed packets are transmitted over the IP network.
Signaling protocols are used to set up and tear down calls, carry information required to locate
users, and negotiate capabilities.
VoIP is based on IP, and IP is used normally for data traffic. Real-time issues are of more
concern when voice and data are transported on the same network. These issues include voice
quality, interoperability, and scalability.
This chapter introduces the 1862 VoIP IAD. It includes a product overview, description of the
product features and applications, and explains the functions of the Front panel LED indicators.
