Over the years, the IP phone has become the dominant telephone technology for both individuals and professionals. Even the large telephony providers are gradually converting their analog systems to this technology. In this article, we provide an overview of how Internet telephony technology works and what it can do for professionals.
How does IP telephony work?
It’s pretty simple: IP telephony, also known as Voice Over Internet Protocol (VoIP), is a method of making phone calls over the Internet using TCP / IP. Instead of using a separate network of phone lines, the signal is carried over the web infrastructure like other data does when surfing the Internet. If you’ve ever made a call using WhatsApp or Apple FaceTime, you are probably familiar with IP telephony.

What are the differences to traditional telephony?
The difference to conventional telephony begins right at the beginning of the signal chain, namely at your TAE telephone socket: It is no longer necessary. Instead, the phone is connected to the DSL router or a VoIP-enabled cable modem.
The signal transmission differs fundamentally from conventional telephone technology. This is due to the fact that speech is divided into data packets, sent independently of one another over the network and reassembled correctly at the destination, as is the case with other data on the Internet.
The advantages of IP telephony
- Cost reduction
IP telephony significantly reduces communication costs. For example, there is no longer any difference between international calls and domestic calls. You don’t have to ask yourself the question, you can call anywhere in the world. Don’t worry, IP telephony tool integration is free and managed on the latest generation of CRMs.
- Advanced features
This is the main advantage of IP telephony: the software and CRMs that operate IP telephony are constantly updated. There are also many advanced features such as the automatic answering machine, voicemail, call recording or even the (very handy) virtual switchboard that keeps you always available.
As you’d expect, you don’t need to be near a telephone system to use VoIP. You can receive your calls anywhere from your smartphone, laptop, tablet, or even your smartwatch, as long as you have a good internet connection.
IP telephony is based on cloud infrastructures. Specifically, this means that wherever there is an Internet connection, there is a telephone line for your company. An essential prerequisite for the continuity of your activities.
The essential elements for using IP telephony
Three things are required for VoIP:
- Internet connection (as reliable as possible)
- A VoIP compatible device (smartphone or other)
- A VoIP service provider
Finally, professionals who want access to IP telephony must register with a registration server. VoIP offers excellent audio quality. You no longer have to worry about interruptions or delays in voice transmission. Last important point: IP telephony adapts to your Internet signal. This means that you can enjoy good transmission quality even if you only have a weak connection.
