What is VoIP, and Why Should Businesses Fully Transfer Their Phone Systems to it?

Many businesses are now looking at the possibility of moving their communications over to a VoIP (Voice over Internet Protocol) system. This change has been happening for a few years, but the announcement that PSTN (Public Switched Telephone Network) will be switched off in 2025 has made the decision more urgent. But, what is VoIP, and why should businesses fully transfer their phone systems to it?

What is VoIP?

Voice over Internet Protocol has been around for some time and is a reliable way to make calls over the internet without the need for a traditional telephone line.

Although VoIP is a newer technology than the old PSTN network, it is actually cheaper and has far more capacity than the old copper wires. This is just one reason why you should be migrating to VoIP.

If your business has an internet connection, then the technology is already there to make and receive VoIP calls.

How Does VoIP Work?

Your internet router is the key to VoIP calls. You will need to have a VoIP service provider which may be the same as your internet provider.

When you dial a telephone number on your VoIP phone, the VoIP service provider will send the digital signal to the other number.

Once the connection is made, the data is exchanged and converted back to sound at each end.

This system doesn’t need traditional telephone lines at all, which will be a major boost to your telephone’s reliability.

What Are the Benefits of VoIP?

Although the traditional telephone lines have been a reliable way to place calls for over 100 years, there are many benefits to switching to VoIP calls.

  • Many companies that have made the switch to VoIP have seen a reduction in costs. Some have seen far lower telephone bills as a result.
  • A big benefit is an increase in the quality of sound. Because all of the calls are digital, there is no degradation of signal that can happen with PSTN. It means that calls to anywhere in the world will sound crisp and clear.
  • There are other features that you can add to a VoIP system such as call monitoring and call recording. This will improve employee training and security.
  • For those who work from home, there is no need for a special setup, it will work wherever you are. You can also use the business telephone number anywhere you are working.
  • The cost of calling other countries can be significantly lower than traditional calls. This will make communication between suppliers and other areas of the company a lot more affordable.
  • VoIP systems use a safe and secure method of sending data. This means your personal information and that of your company will be safe.


Traditional fixed landlines have been a staple part of communication in the UK for many years. However, to keep progressing and improving technology, this old system needs to be replaced. By switching to a VoIP system, you can reduce your costs, improve your call security, and ensure your company is ready for the future.
