Hosted VoIP business telephony system overview

Hosted VoIP phone systems that transform UK business communication

From simple VoIP phone systems for small businesses, to scalable integrated communications systems that keep larger organisations connected with seamless flexible working and collaboration, our advanced hosted telephony solutions bring your business, team and customers closer than ever.

Why hosted VoIP is the future for UK businesses

VoIP will soon be the standard for business and domestic telephone communications. The traditional Public Switched Telephone Network (PSTN) and Integrated Services Digital Network (ISDN) are being switched off, with the UK landline switch-off due by 31 January 2027. Moving to one of our hosted VoIP phone systems means you can keep your existing numbers.
These older networks are prone to disruption and are hard to maintain, so VoIP is becoming the new normal for remote communications. Systems such as the advanced hosted VoIP that we offer allow for seamless communication via internet connections and work over a range of devices.

Our hosted telephone systems

We offer three hosted telephone systems UK-wide, from VoIP for small businesses through to large international organisations.

Your Questions, Answered.

What is a hosted phone system?

Expand icon
A hosted phone system runs your business calls over the internet instead of traditional phone lines, so your team can make and take calls on desk phones or the desktop and mobile apps, wherever they’re working. With Flotek, you can keep your existing numbers, and we’ll install it, train your team and support you seven days a week.

How long from first contact to installation completion?

Expand icon
Once you get in touch, we’ll quickly assess your needs and send over a tailored quote for your hosted VoIP phone system. If you're ready to proceed, you can sign online, and we’ll take care of the rest – whether that’s migrating your existing numbers or setting up new ones.
We can ship pre-configured handsets directly to you, set you up remotely the same day, or schedule an on-site installation with training – usually within 7 days, anywhere in the UK.
‍
For larger or more complex installations, timelines may vary depending on factors like data cabling or site readiness. However, we always aim to work to your schedule and minimise disruption.

Can I keep existing phone numbers when switching to hosted VoIP?

Expand icon
You can. When we set up your new hosted VoIP, we’ll port over any existing numbers, ensuring a quick and efficient setup from start to finish. We can also set up any new numbers you might need on an ongoing basis.

What do I need on-site for installation?

Expand icon
As a baseline, you will need a stable internet connection and spare power sockets. Our team can assess your site ahead of the installation and bring any additional equipment with them on the day to ensure a seamless setup. If you prefer, you can add extras such as hardware, which we can also provide and install.

Is training provided for the new hosted VoIP system?

Expand icon
Absolutely! After we install your new hosted VoIP system, our team will provide you with straightforward training and ensure that you’re fully equipped to get the best out of your system. You’ll also have a variety of options for ongoing training, such as video sessions and access to our online learning portal.

What happens if I need help after installation?

Expand icon
If you need help at any point after we install your hosted telephony solution, you can reach us seven days a week via telephone or our technical support desk. We’ll also monitor your system remotely to spot any issues as they arise.

What uptime and call quality can we expect?

Expand icon
To an extent, your uptime and call quality will depend on the strength and stability of your internet connection. We only offer hosted VoIP phone systems that we trust ourselves, with options like Microsoft Teams Phone offering 99.999% uptime. If you ever have issues with call quality or uptime, our expert team is always on hand to provide support and can even attend your site if needed.

How quickly do we respond to VoIP support issues?

Expand icon
With proactive monitoring and our technical support desk, we can guarantee a quick response if you experience any issues with your hosted phone system. We have more than 100 experts on standby to provide fast, effective resolutions.

Do you offer SLAs for reliability?

Expand icon
We do. We promise a 15-minute response time for critical issues and a resolution within 24 hours, helping keep downtimes to a minimum and ensuring you stay connected no matter what.

Is VoIP secure and GDPR compliant?

Expand icon
All of our cloud phone systems are highly secure and completely GDPR compliant. Our solutions use data encryption to keep information protected and ensure details are stored in accordance with data protection regulations.

What happens if the internet goes down?

Expand icon
If you experience an internet outage at any point, you should still be able to make calls via mobile devices through call routing. Make sure to contact our team as soon as possible and we’ll do everything we can to get you back online as soon as possible.

Can we use existing phones and headsets?

Expand icon
Some desk phones and headsets are compatible with VoIP systems, and if your existing hardware is compatible, we can integrate your new hosted VoIP with these devices. If not, we can provide a full range of compatible hardware.

Are international calls included?

Expand icon
Our hosted VoIP solutions include unlimited UK calls, but international calls are not available as standard. We can provide cost-effective international calling as part of your plan however, and we’ll discuss your specific needs when issuing your free quote.
