Whichever option you choose, your calls run on a network we own, and the team that runs it is the team you call.
Quality we control.
We own and run the network, so we monitor and manage call quality at every stage, including at your busiest times.
One team answers.
24/7 cover for business-critical faults. A 15-minute response target and a 4-hour repair target, backed by a specialist team.
Service levels in writing.
Response and repair targets are written into your service agreement, with service credits of one to five days’ monthly fee if we miss a repair target.
Numbers in 140+ countries.
Local and international numbers from the same supplier, served from seven data centres, so a new office joins on day one.
Run it yourself if you want to.
New customers can add SIP trunks and numbers themselves in affINITy, our customer portal.
Free UK porting.
Porting is free for UK numbers and many international ranges, and any charge is known before the port goes ahead.
Yealink phones and headsets, ready for day one.
We supply the full range of Yealink devices that 3CX supports, so the phones, headsets and meeting-room kit come from the same team as your phone system. Plug a phone in and it sets itself up for your 3CX, and when something needs attention you call one number.
Desk phones.
Yealink IP desk phones, from reception to the boardroom, with your extension, directory and presence ready to use.
Cordless DECT.
Move around the office, warehouse or shop floor and stay on your business number.
Headsets.
Wired and wireless Yealink headsets for clear calls at the desk, at home or on the move.
Video and meeting rooms.
Yealink video conferencing and collaboration bars that turn any room into a meeting room.
Buy or lease. Buy your hardware outright or spread the cost with a lease.
Keep what works. We check your existing handsets and tell you which can stay.
Calling in Microsoft Teams? We also supply Yealink Teams-certified phones, headsets and Teams Rooms devices, which you add in your Teams admin centre.
Moving to VoIP, in three steps.
Tell us how you work.
Show us how customers reach you, the numbers you use and your current phone system. We recommend the right option, with a clear monthly price.
We prepare and test the move.
We set up your new service, move your numbers and test calls, menus and transfers with you before the switch.
Your team is ready on day one.
We train your people on answering, transferring and voicemail, and stay your contact for changes as you grow.
Number porting typically takes 7 to 15 business days, though timescales vary by number type and country.
Business VoIP questions.
Can we keep our existing phone system?
Yes. Infinitel SIP trunks work with most IP phone systems. Your system’s maintainer keeps looking after the system itself, and we look after the calls.
Can we keep our desk phones?
Yes, where they are compatible. We check your handsets and any analogue lines, such as alarms, lifts or fax, and tell you what can stay and what needs an adapter or replacement before the move.
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.
Can we make business calls away from the office?
Yes. The 3CX apps and Microsoft Teams let staff use the business number on a laptop or mobile anywhere with an internet connection. Mobile data or roaming charges from your mobile provider may apply.
What happens if our office internet goes down?
Your team keeps taking calls on the 3CX app, on their mobiles.
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.
Move your calls to VoIP with one conversation.
Tell us how your team handles calls today. We’ll recommend managed 3CX, Teams calling or SIP trunking, and give you a clear monthly price for calls, setup and support.
