13.6.1 VoIP
VoIP is the sending of voice signals over 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.
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.
