What is the difference between an Analogue and a
Digital IP (VoIP) telephony Intercom system?
Analogue Systems Analogue telephony intercom systems are similar to the kind of phones that you have been using for years. Also commonly known as public switched telephone network (PSTN), analog phone service allows subscribers to communicate with one another. These users are connected through a copper wire subscriber loop which runs from a central switch office to many homes and businesses. Each subscriber is assigned a specific phone number, which allows them to contact one another. The phones in your house are, quite likely, analog phones. That means they're extremely reliable, familiar and very easy to use. You just plug them in, and they do what they have always done. Digital IP Systems Digital IP intercoms are a slightly more complicated, since they're a little more like computers, with servers, and regular maintenance required. VoIP (or Voice over Internet Protocol) is a general term used to describe various transmission technologies, communication protocols, and methodologies that are used to provide voice communication over an internet connection rather than a POTS (Plain Old Telephone Service) copper line. There are, however, some reasons why you might want to use IP phones as well as or instead of analog phones. For example, businesses frequently use VoIP because it offers a secure and quality service. They can manage calls over their own private networks. Advanced technology has provided new forms of VoIP. It offers more than communication – users can also host web and video conferences with VoIP. Analog advantages include:
