The Service Configuration

10.1 Overview

The VOICE > Service Configuration screens allow you to set up your voice
accounts and configure your QoS settings.
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 it's 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.
