Advantages and Disadvantages of VoIP

Table of Contents

Older phone systems are being gradually phased out as more businesses are adopting VoIP technology. Telecom providers are also actively encouraging their clients to switch to VoIP in light of the PSTN Switch off happening in 2025.

You might be wondering how your business might benefit from the switch, and is it all sunshine and rainbows? In this post we will cover some of the Advantages and Disadvantages of using VoIP phone systems.

What is VoIP?

Voice over Internet Protocol (VoIP) is a technology that allows you to make calls over the internet. It converts analogue voice calls into digital data that is sent over the internet in the form of data packets.

Advantages of VoIP

  • Costs – VoIP systems only require an active internet connection to make calls. This means you’re only paying for an internet connection without the need for a phone line. This makes VoIP cheaper than traditional phone systems.
  • More Features – VoIP gives you more control over your phone system. It includes features like call recording, call forwarding, remote management, call distribution and voice recognition. You can get some really fancy tech if you’re got the budget for it.
  • Integration – VoIP allows you to integrate with other systems within your business. For example your CRM to pull up existing customer data when a client calls.
  • Portability – VoIP can be used with compatible softphone apps which give you the ability to use it on any device from anywhere in the world as long as you have access to the internet.
  • Scalability – You can easily upgrade or downgrade the number of users on your VoIP system, only paying for the number user licences you need at any given time. 

Disadvantages of VoIP

  • Audio Quality – the quality of your calls depends entirely on your broadband speed and reliability. If you have really slow broadband that cuts out constantly, your calls will suffer.
  • Needs Internet – VoIP requires an active internet connection. This can become a problem if your internet goes out, as you will be left unable to make calls, even to emergency services.
  • Security – As VoIP connects to the internet it is exposed to many of the cyber security risks that other devices like computers are.

Conclusion

There are some drawbacks to VoIP because of its dependency on an internet connection. However, high speed, reliable broadband is becoming more and more available in all areas of the UK negating most of those drawbacks.

Should your business use VoIP? Short answer is yes. There are many benefits VoIP offers, often at a much lower price than traditional phone systems. It gives smaller businesses the opportunity to make use of features that would normally be out of their reach. 

Additionally, from December 2025 PSTN services will be discontinued in the UK. Which means you will need to switch to alternative phone systems anyway.
