What is a VoIP phone system and how does it work?

VoIP (Voice over Internet Protocol) is a solutions where voice calls are transmitted over IP networks using an internet connection, rather than over the traditional telephone network. A VoIP phone system works by taking analogue voice signals, digitalising the sound, compressing it to make voice packets smaller, then breaking it up and sending it as data over an IP network to both desktop and mobile devices. VoIP for business enables VoIP call routing to take place via a secure internet connected data centre rather than through hardware installed on your business premises. Internet-based means the technology is easy to install, there are no upfront connection costs, it’s easy to maintain and upgrade, plus it’s brilliantly agile – meaning the system grows with your business together with delivering an impressive repertoire of powerful call management features.

Frequently asked questions

A VoIP phone system does everything your traditional business phone system does, and so much more. It comes hand-in-hand with all the call management features you need to run your business effectively, such as call forwarding and routing, call transfers, automatic messaging and so on – but with the game-changing flexibility of being able to utilise these functions on any internet-enabled device and from wherever you are.

The best phones for VoIP are IP phones as they have been designed for use with VoIP and have call management features which most conventional phones lack. However, if you’re keen to retain your existing PSTN-based landline phones, you can use an analogue telephone adaptor which will allow your phones to work with VoIP technology. The Horizon phone system seamlessly integrates with most on-premise phone systems and provides a wide range of features that can be managed through the desktop or mobile applications.

The short answer is yes! Cost-effective, flexible, agile, secure, scalable and easy-to-use, plus a wealth of call management features…the list of benefits goes on. An industry leading business phone system such as Horizon VoIP is future-proof and will quite simply transform the way you do business.

VoIP for business, otherwise known as a cloud phone system, works by using your business phone number app or VoIP adapter to convert an analog audio signal into a digital signal that can be sent using packets over the internet. This digital voice data is then sent to your business VoIP phone system provider using your internet connection, and then finally the message is routed to the end user who is recieving the call.

Cloud-based phone systems and Hosted VoIP phone systems are essentially the same thing and have the same functionality. The cloud turns any device with internet access into a potential phone using the voice over internet protocol. VoIP intergrates a business phone system with the cloud to provide a range of voice service over the web including extension dials, instant messaging, video calls, and voicemail management.
