The right phone system for how your people work.
Managed 3CX, calling in Microsoft Teams or SIP trunking for the phone system you already have. All three run on our own network, with one team answering for the whole service.
“Great service, very responsive help, very stable system – I can’t ask for more.”
Matt ConnattyIT Director, One.org
Why move your phones to the cloud.
An on-premises phone system ties your calls to one building and one box in a cupboard. A cloud phone system goes wherever your people go.
Your number on every device.
Desk phone, laptop or mobile: your team answers the business number in the office, at home or on the road.
Grow in step with the business.
Add a new starter, a new team or a new office through a change request, not an engineer visit.
One predictable monthly cost.
The system, its hosting, your calls and support on one bill, instead of hardware, maintenance and line rental from different suppliers.
Calls keep flowing when the office can’t.
If a site loses power or access, calls ring on your team’s apps wherever they are working.
Offices abroad, on the same system.
Local numbers in 140+ countries, so a new office joins the same phone system on day one.

Every caller reaches the right person.
A better phone system helps the person answering as much as the person calling. Colleagues see who is free, find the person they need and transfer a call with context.
A clear welcome for customers.
Callers reach the right person first time: menus, queues, hours and overflow set up around your teams.
One team, wherever they sit.
Office, home or on the road, everyone has the same business number and the same features.
The real differences,
side by side.
Every charge is listed, so you can compare like for like.

Questions about choosing a business phone system.
Which option is right for us?
Choose managed 3CX if you want one system for calls, apps and customer queues. Choose Teams Direct Routing if your people already work in Microsoft Teams. Choose SIP trunking if you are keeping a phone system you are happy with. We’ll recommend one after a short conversation.
Can we keep our numbers?
Yes. Porting is free for UK numbers and many international ranges, and any charge is known before the port goes ahead. It typically takes 7 to 15 business days, though timescales vary by number type and country. Your current provider may apply its own charges.
Which phones can our team use?
Yealink desk phones, DECT and headsets, the 3CX or Teams apps, or both. We check your existing handsets and tell you which can stay.
What do we need for Teams calling?
A Microsoft Teams Phone licence for each user who makes calls, which comes from Microsoft. We check your licences and tenant settings before we quote, so there are no surprises. Our service levels cover the SIP trunks and managed SBC; Microsoft’s own service is covered by Microsoft.
Can we have numbers in other countries?
Yes, in 140+ countries. Availability and paperwork vary by country and number type, and we tell you what each needs before you order.
How do we get started?
Tell us how your customers reach you and how your people work. We recommend a system, agree the call flows, move your numbers, test everything with your team and train them before the switch.
