What Is VoIP?

VoIP, also known as Voice over Internet Protocol, is the ability to make and receive calls over the internet at a very low cost from anywhere in the world. VoIP telephone systems are becoming increasingly more popular, especially within the business world as more and more companies are seeing the benefits of a more cost-effective and flexible telecoms solution.

Benefits of a VoIP System

VoIP systems work by transferring your voice data into digital information that is then sent via the internet. Due to data being passed in this way, rather than traditional copper wires, VoIP systems are a more flexible solution for businesses in today’s workplace.

  • Cost

VoIP is known for being a much more cost-effective solution that your traditional lines and calls package which uses analogue copper lines. But don’t confuse this with being a “cheap option”. VoIP has much higher quality voice calls when coupled with a good broadband provider.


  • Scalability

Whether you need to scale your business up or down, VoIP systems make user management simple. You can add and remove a user easily via a customer portal or we can do this for you. There are no expensive hardware costs and there is no limit on the number of users you can have.

  • Features

With a VoIP telephone system, you will benefit from a number of fancy new features which are updated regularly to ensure you get the most out of your system. From live call statistics to video conferencing and much more, your business will get a host of features to improve your operations.


  • Remote Working

With workforces now operating in a more remote set-up, businesses require telephone systems that allow them to connect seamlessly with employees, customers and suppliers. VoIP allows users to twin their desktop and mobile device, display their office number and communicate across various devices including mobile, tablet, laptop and desktop. You have the option to set-up an auto-attendant with call routing to individual departments, giving your customers the best possible experience no matter where your employees are located.

ISDN Switch Off

BT has announced the end of life for traditional ISDN and PTSN lines from 2025. This means businesses will no longer be able to purchase additional lines and infrastructure will not be supported by BT Openreach. Although these lines are still available to purchase for a limited time, it would be best to start thinking about upgrading your system to ensure business continuity is not affected.
