Simply better

Increased Productivity

The move to all-digital isn’t just because the old phone system is, well, old. It’s because all-digital communications are so much better. Even at the most basic level, you’ll be able to make and take calls on any device, from wherever you are, from the same number. 

Expanded Features

Doing More

You’ll link your business applications and systems with video chat, calls and collaboration, so you’re closer to customers and colleagues alike. And with everything in the cloud, you’ll be able to access systems from anywhere, working from wherever you want. 

Added Value

Lower Costs

Factor in the lower costs that IP can bring and it makes sense to get your skates on and go digital as soon as you can. There’s no need to wait until the last moment.

Yes. As an essentially 20th Century technology, the PSTN network is increasingly out of kilter with the demands of 21st Century communications. As more and more people switch to mobile and the internet communications, the demands on PSTN are more than they were designed to deliver. Which is why Openreach is switching to IP.

You need to start planning your move today because there could be a lot to do. Remember, it’s not just about calls. You need to review everything you’re connecting to your phone lines, such as door entry systems and alarms monitoring.

The closer we get to the 2025 switch off date, the more in-demand suppliers will be to convert their customers from analogue to digital. The earlier you switch, the smoother the process will be.

Actually, it can be very easy – with the right planning. If you’re running separate voice and data networks, you can bring them together, as long as your network has the bandwidth (and if it needs a top-up, we can arrange that). You can swap out your entire phone system in one go or take a phased approach and introduce it one office at a time. It’s up to you.

It’s even easier when you opt for a hosted service. That means we’ll take care of installation, set-up, and on-going management. Digital phone systems come with IP (internet protocol) phones, which is the type of phone you need to make calls over the internet rather than the PSTN network, so you’ll need to replace your current handsets if they’re not compatible with digital phone services.

All you need to do is plug an IP phone into the network or download an app and use a headset, and you’re ready to make and receive calls.

You’ll be able to keep your current numbers, if you want to. It’s actually an opportunity to review your numbers and think about whether you still need them all.

One of the big advantages of digital systems over traditional landlines is that you can have the same number on multiple devices, wherever you are. So customers can ring your office number and you can answer the call literally anywhere you can get an internet connection. You’ll never miss a call again.

Not at all – you can keep your existing analogue devices by simply adding one of our digital gateway devices. You can upgrade to a feature-packed digital phone system when the time is right for your business.

It is not as expensive as you may think. Digital phone systems are easily scalable so you can grow and shrink as needed without the pricey work involved with PSTN equipment. These systems are cost-effective in operation too.
