Are You Looking For Top VoIP Providers For UK Businesses?

If your company is still relying on an old telephone system, now is a great time to make the transition to VoIP.

Although the ISDN (Integrated Services Digital Network) and PSTN (Public Switched Telephone Network) have been extended to January 2027, many companies have decided to update their telecommunications sooner rather than later. 

This switch-off means that all companies currently relying on these legacy networks will need to transition to modern alternatives like VoIP.  

VoIP uses internet-based technology to handle your voice, video, and data communications. It offers many different benefits including superior connectivity, flexibility, and  lower running costs. As experienced providers of this type of system, we can work with you to make the switch. 

Criterion Systems provides the latest business communication solutions, along with mobile phones and competitive line rental rates.

No matter if you run a small business or medium-sized enterprise, we can provide solutions for from 2 to up to 500 users.  

Options we provide include hosted, hybrid telephone systems and Pure IP business telephone systems. The latter, also known as an IP telephony system or VoIP (Voice over Internet Protocol) system, transmits voice calls over an IP network instead of traditional telephone lines.

When it comes to hosted telephone systems, we work with businesses in an array of industries, including estate agents, charities, educational institutions, solicitors, GP surgeries and recruitment agencies. 

If you’re looking for trusted VoIP providers for your business, don’t hesitate to contact us for more information.
