VOIP & SIP - Flexible voice that scales with your business.

VOIP & SIP

VOIP and SIP are both ways of making calls via your broadband connection using IP (Internet Protocol) technology. We offer a range of VOIP & SIP solutions which we’ll tailor to your business needs.

All the features you’d expect from a traditional phone system are available but without the on-site hardware. This makes VOIP and SIP much more cost-effective, easier to manage, and free to move wherever it needs to be. Unlike many VOIP vendors, we’re not tied to a specific provider or model. That means we can provide per-user or per-system models, depending on which is most cost-effective for you.

We can also provide features that many off-the-shelf providers can’t, such as Microsoft Teams integration or compliant call recording. Most importantly, our VOIP solutions are continually updated. This keeps them secure and means you always have the latest features. And it means they’re fit for modern business now and forever.

VOIP for Microsoft Teams

VOIP for Microsoft Teams

Enable external dialling for selected Microsoft Teams users without the need for full-scale adoption.

The rush to adopt Teams has left many businesses wanting to enable its use in the right areas, but restricting it in others. Otherwise, costs can escalate, especially with Microsoft’s licensing and expensive calling plans.

Our VOIP for Microsoft Teams gives you the solution. Users needing only simple calling features use our low-cost VOIP extensions. Teams users get external calling enabled via their Microsoft Teams apps, or via our VOIP apps if preferred. But the whole system still acts as one. Inbound calls can be routed as required. Internal calls are still free, whoever makes them.

It’s the perfect way to a controlled adoption of Microsoft Teams and Office 365.

Hosted SIP Extensions

Hosted SIP extensions are the simplest way to connect one (or just a few) business extensions. With analogue lines about to be discontinued in the UK, our Hosted SIP Extensions are a simple, cost-effective replacement.

Each extension gets a phone line, inbound number, voicemail and a softphone or handset.

Hosted SIP is best for sole traders or very small businesses. For a more feature-rich solution consider Hosted VOIP per User.
