About our professional services


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.

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 employees’ mobile phones with the mobile app to allow them to make and receive calls from any location. They will be able to make and receive calls from their mobile without displaying their personal contact details, displaying their office direct line and have access to the business’ global address book.
