10.1.2 What You Need to Know About Network Setup

The following terms and concepts may help you as you read through this chapter.
VoIP
VoIP (Voice over IP) is the sending of voice signals over the Internet Protocol. This allows
you to make phone calls and send faxes over the Internet at a fraction of the cost of using the
traditional circuit-switched telephone network. You can also use servers to run telephone
service applications like PBX services and voice mail. Internet Telephony Service Provider
(ITSP) companies provide VoIP service. A company could alternatively set up an IP-PBX and
provide its own VoIP service.
Circuit-switched telephone networks require 64 kilobits per second (kbps) in each direction to
handle a telephone call. VoIP can use advanced voice coding techniques with compression to
reduce the required bandwidth.
SIP
The Session Initiation Protocol (SIP) is an application-layer control (signaling) protocol that
handles the setting up, altering and tearing down of voice and multimedia sessions over the
Internet.
SIP signaling is separate from the media for which it handles sessions. The media that is
exchanged during the session can use a different path from that of the signaling. SIP handles
telephone calls and can interface with traditional circuit-switched telephone networks.
