We have a range of flexible solutions available, from simple voice licenses for small business users, to cloud-based calling for Microsoft Teams. Replace your legacy telephony systems with digital phone services and empower users with a modern communication experience.

With mix and match licenses, you get the Voice One package that’s right for your business. We listen to your needs and create the optimum blend of services and license types.

Hate paying for extras you don’t need? Not all users have the same requirements when it comes to voice communications. While some will need basic calling features and functionality, others may require a more feature-rich experience.

With Voice One, it’s easy to mix and match different licenses. This means individual users get the functionality they need, and you don’t pay for additional features for users that don’t require them. Our team will create the package for you based on your different user requirements. And you’ll have one neat bill. No complexity. No confusion.

We’ll work with you to identify the different types of users across your organisation and establish their requirements. Then, we’ll recommend the licenses with the features that will fulfil these while providing you with the best value. You get one, tailored Voice One bundle with one simple monthly bill. And users get the digital voice solution they need.

What is the 2025 PSTN Switch-Off and How Will it Affect Your Business?

For decades, phone calls in the UK have been carried over a network of copper lines. This is known as the public switched telephone network (PSTN). This has served the country well, but it’s no longer able to keep up with the demands of modern business. And so, it’s being replaced with a digital alternative.

The digital choice enables you to make phone calls over the internet while also offering greater support for things like video calling and file sharing. Openreach, which is managing the network upgrade, is planning to switch off PSTN by the end of 2025. That means all businesses will need to have moved to digital phone lines by then. After this point, legacy phone systems and services will no longer work.

Moving to a Voice One solution will ensure your business is future-ready, while also providing you with the flexibility and simplicity you need when it comes to telephony. Get in touch with a member of our team to build a Voice One solution that works for you.

How Does Voice One Help?

With Voice One, you can provide users with simple cloud voice experiences and replace your existing analogue phone system with a future-ready solution. Our digital phone services encompass two core types of internet telephony. This enables you to find the best way to make the move to cloud-based calling.

Hosted SIP Trunking: If you have a private branch exchange (PBX) device and use ISDN, Hosted SIP Trunking lets you connect your phones to the internet. That means you can keep your current phones for now and still get the benefits of the cloud – perfect if you want to stagger your transition to digital.

Hosted Centrex: A complete digital solution, Hosted Centrex is a cloud PBX service. It replaces your on-site analogue phone system with a digital alternative. You then make calls through internet protocol (IP) phones, as well as computer and mobile apps. If you’re ready to go fully digital, this is the solution for you.
