Hosted Telephony for UK Business — a Cloud Phone System That Flows
DragTech designs, delivers and supports hosted telephony for small and medium UK businesses. Your switchboard moves to the cloud, your numbers come with you, and every call follows a flow you actually chose.
Our hosted voice platform, DragFlow, puts calls, chat, meetings and your whole switchboard in one secure desktop and mobile app — provisioned, ported and looked after end to end by UK engineers.
What is hosted telephony?
Hosted telephony — also called hosted VoIP, cloud PBX or simply a cloud phone system — is a business phone service where the switchboard runs in a data centre rather than in your building. Calls travel over your broadband or ethernet connection, and your numbers, greetings, menus and routing rules are configured in software.
Because nothing physical sits on site, there is no maintenance contract on a dying PBX, no engineer visit to change a greeting, and no limit tied to the number of copper lines into the building. You add or remove users as the team changes, and the system grows with you.
It also matters right now: the UK's traditional PSTN and ISDN network is being retired, so every business still on analogue lines or an on-premise switchboard needs a migration plan. Hosted telephony is that plan.
What you get with DragTech hosted telephony
Everything a UK SME needs from a cloud phone system, tailored to how your team actually answers the phone.

Queues, wallboards and overflow routing so nobody rings out to voicemail during a rush.

Engineers and reps take office calls on their mobile, presenting the company number.
Regulated and recorded environments
Call recording, retention and search where you need an audit trail.
How we move you to a hosted phone system
- 1
Listen
We map how calls reach you today — who answers what, where calls get stuck, and what your team wishes it could do.
- 2
Design the flow
Menus, opening hours, groups, queues and escalation are drawn out and agreed before anything is built.
- 3
Check the connectivity
We test the line into your building and, where needed, provide broadband or ethernet sized for voice.
- 4
Build and port
Users, handsets and apps are provisioned, then your numbers are ported with the old lines kept live in parallel.
- 5
Train and cut over
Your team is shown the app, we cut over out of hours, and a DragTechie stays with you through the first days.
- 6
Keep tuning
Call flows are never finished. Ask us for a change any time — it is part of the service, not a chargeable visit.
Hosted telephony questions, answered
What is hosted telephony?
Hosted telephony is a business phone system that runs in the cloud instead of on a switchboard in your building. Calls travel over your internet connection, your numbers and call routing live in a secure UK data centre, and your team makes and takes calls from a desk phone, a desktop app or a mobile.
How does hosted telephony work?
Your existing numbers are ported to the hosted platform. Incoming calls arrive at the platform, which applies the call flow you have designed — opening hours, auto-attendant menus, hunt groups, queues, voicemail — and delivers the call to whichever device your colleague is signed in to. Nothing on site needs maintaining.
What is the difference between hosted telephony, hosted VoIP and cloud PBX?
They describe the same thing from different angles. VoIP is the technology that carries the call over the internet, a PBX is the switchboard that routes it, and hosted or cloud means that switchboard is run for you as a service rather than installed in your comms room.
Can we keep our existing phone numbers?
Yes. Geographic and non-geographic UK numbers can be ported across, including whole number ranges. We run the port for you and keep your old lines live until the new system is proven.
Is hosted telephony reliable enough to replace ISDN or a traditional PBX?
With the right connectivity, yes — and it is now the only forward path, as the UK PSTN and ISDN network is being switched off. Because the switchboard is in the cloud, calls can be re-routed to mobiles or another site instantly if your office loses power or broadband.
How long does it take to move over?
A small office can be live within days once numbers are confirmed. Multi-site organisations with complex call flows are usually delivered in a few weeks, run in parallel with the old system, and cut over out of hours.
Does it work with Microsoft Teams and mobiles?
Yes. Colleagues can answer on the DragFlow desktop app, the mobile app, a desk handset or through Microsoft Teams, all on the same extension and the same call flow.
