What is VoIP?

VoIP stands for Voice Over Internet Protocol. It is software which you use to route your telephone service through the internet rather than a local phone provider. A VoIP system turns traditional analogue phone signals into digital ones and offers increased functionality over traditional calls. VoIP technology is often cheaper than a traditional phone system and allows a company to essentially ‘work from anywhere’ as long as there is a good internet connection. VoIP services also mean you can perform international calls far more cost-effectively and can use digital tools such as call handling features to gain more insight into your team’s efforts.

A VoIP phone system is quick to install and easy to use. In fact, all you need is business-grade broadband connection as VoIP requires very little technical know-how.

We provide a selection of pre-configured IP phones, so you can plug these into an internet connection and you’re up and running. You could opt for a softphone application on your PC, together with a headset, if you do not need a desk phone.

Our expert support team is on hand should you need assistance in getting set up. You can also read our buyer’s guide to learn more about what you need to know before setting up your VoIP system.

A fast Internet connection, like a fibre broadband through to leased line and SD-WAN connections, is definitely needed for a business VoIP system.

The actual bandwidth depends on the number of concurrent calls that have to be made. If you need to make a lot of calls at the same time you will require more bandwidth.

No. This may have been an issue over a decade ago, but VoIP has improved rapidly to provide high-quality calling. VoIP users would not be able to tell the difference between a traditional phone call and a VoIP one. However, audio quality does depend on a number of factors and network congestion or poor configuration can cause issues.

Yes. We can easily set up your business VoIP phone system to divert all calls to your employees’ Android or iOS mobile phone when they are away from their desks. They will be able to make and receive calls from their mobile without displaying their personal contact details and only displaying their office direct line.

Yes, we do! As leading VoIP providers for business in the UK, Windsor Telecom provides various calling solutions ranging from 100 minutes at £3 per month up to 1 000 minutes at £15 per month.

The bundles are valid for VoIP calls made to the following countries: Australia, Canada, France, Germany, Italy, Ireland, New Zealand, Spain, Sweden, USA, Denmark, Norway, Poland, Chile, Romania, Slovakia, Brazil, Israel, Peru and Puerto Rico.
