Cloud-hosted telephone systems

Now an established technology, a cloud phone system is the perfect solution for businesses of all sizes. With superior connectivity and service levels now available, a cloud-hosted telephony system is a mainstream choice with many businesses deploying hosted telephony in recent years to enjoy improved flexibility and mobility.

What is a cloud-hosted phone system?

Also known as a cloud or hosted PBX, you do not own or have to look after any hardware with a cloud-hosted phone system. Aside from your desk handsets, everything is hosted in multiple data centres to give you a maintenance-free telephony service.

You will also require an internet connection that is suitable for voice. You may be able to use an existing connection, or we can advise you on the best option available in your area. A hosted PBX is perfect replacement for a legacy on-premise phone system that uses outdated ISDN or PSTN lines.

Benefits of a cloud-hosted phone system

Easy growth

A cloud-hosted phone system will grow with your business. You can add extra users as and when, so you only ever pay for what you need. You can even add entire additional offices as a it does not matter where your employees work, as all your hardware is hosted in the cloud.

Cost savings

There is no need for a capital payment as a cloud phone system is paid for on a monthly basis with ongoing support, software upgrades and lower call costs included. This means you only ever pay for want you need while also eliminating the cost of ISDN and PSTN lines.

Perfect for remote working

With many businesses adopting a hybrid working model, a cloud-hosted phone system is perfect for remote and mobile workers. They can use a handset or softphone app on mobile devices and PCs to make, receive and transfer calls as they would in the office. Any outgoing calls will display the main business number.

All the features

You will not lose out on features if you choose a hosted PBX. All the functionality you are used to is still available to you, including voicemail, voicemail-to-email, hunt groups, call recording and queuing, call centre, etc. You can also integrate your cloud phone system with a range of CRMs to enjoy improved productivity.

Choose your number

You can take your business phone number with you or choose a new one. You can extend your geographic footprint with local numbers in areas you want to move into. Whatever you choose, your number can be used to reach you wherever you are working as you will receive calls on both your desk phone and your mobile.

Prepare for PSTN and ISDN switch-off

A cloud phone system is the perfect replacement for a traditional phone system that uses copper PSTN and ISDN lines that are being withdrawn by Openreach at the end of 2025 at the latest. You will still have the features you are used to with increased flexibility and lower call costs.

Frequently asked questions

1. What’s the difference between a cloud-hosted and on-premise phone system?

The main difference between a cloud-hosted phone system and an on-premise solution is the ownership of the phone system and software itself. An on-premise PBX is all yours and is your responsibility. A hosted PBX is owned and managed by the cloud provider, is managed at cloud level, and your business connects to it via the internet.  

2. Is the call quality of a cloud PBX good enough?

This is where your choice of internet connection is important. Running a hosted telephony service over an existing broadband connection that you already use for your data is usually a mistake. We will give you advice on the right connection to ensure you enjoy HD voice quality.

3. What if I cannot get into the office?

You will still be available to your customers and suppliers, as calls can be received remotely, and you can still make calls. You can amend voicemail messages remotely to warn your customers if your premises are closed due to snow, flooding, etc., thus offering true business continuity.
