Digital vs. Analog office phone systems

Most newer and more expensive phone systems communicate via digital technology. This means that sound is transmitted as bits of data rather than audio waves.

Theoretically, digital transmission has many advantages over analog transmission. Digital signals are less affected by interference and line degradation, meaning that digital lines have virtually no static or hiss.

However, most businesses make outgoing calls over regular analog lines. This means that even a digital phone system must convert signals back to analog waves whenever a call leaves the office. Because very little sound degradation occurs within the smaller confines of an office, analog systems actually sound about the same as their digital counterparts. The main reason for buying a digital system is that these systems tend to be better equipped to connect with accessories such as voice mail or caller ID.
