VoIP Phone Systems in Windsor
A VoIP phone system for Windsor businesses that want one number for the whole team. Take calls on a desk phone, laptop or mobile app with your 01753 numbers, in the office or at home. We move your numbers, set up handsets and get you off copper before the switch-off.

One Business Number, Every Device
A cloud phone system, also called hosted VoIP, runs your calls, messages and video meetings over the internet instead of copper lines. Numbers, call menus, queues and closed-hours rules all live online, so they work on desk phones, laptops and mobile apps.
Your team keeps its existing 01753 numbers, or takes a new local or national number, and uses them on a desk phone, a softphone or the mobile app over Wi-Fi, 4G or 5G. Outgoing calls show your business number, so personal mobiles stay private, and calls ring wherever staff work.
Openreach aims to close the analogue PSTN by the end of January 2027, so now is a good time to move your Windsor phones off copper.

Why businesses switch
Why Windsor Offices Move Over to VoIP
Most Windsor firms call us when their old business phone system starts getting in the way. These are the problems we fix most.
Missed calls away from desk
The office phone rings unanswered while staff visit a client in Slough or work from home in Ascot. A cloud phone system rings their laptops and mobile apps on the same number.
PSTN and ISDN lines switching off
Openreach aims to close the analogue network by the end of January 2027. We trace every line, including alarms and card terminals, and move each one in time.
Paying rental on unused lines
Many businesses still pay for ISDN channels, old fax lines and dead numbers. We cancel the spare lines and port the numbers you want to keep.
Choppy calls on busy broadband
Voice needs a steady connection more than a fast one. We test your line, put calls first on the router and suggest an upgrade or backup where needed.
Phones, apps
IP Desk Phones and Apps for Your Whole Team
Prefer a handset on every desk? We supply, configure and install IP desk phones on your VoIP system, and staff who work from home or travel use the laptop or mobile app on the same number.
IP Desk Handsets
Some existing handsets work with a cloud system, but older analogue and ISDN phones do not, so we check your kit during the line audit. Where you need new handsets, we set them up before the switch and show staff how to use them. Reception and sales desks get call queues, hunt groups and hold music.
- Checked during the line audit
- Hunt groups that ring phones in order or all at once
- Set up and tested before the switch
Softphone and App
Staff driving the M4, visiting clients in Egham or working from home in Maidenhead take office calls on the laptop or mobile app, and outgoing calls still show your 01753 number. If the office line fails, calls divert to mobiles or another site, and staff answer on the app over 4G or 5G.
- Your 01753 number shown
- Answer calls over 4G, 5G or Wi-Fi
- Teams calling if your staff want it
Getting started
How to Switch to Business VoIP
Moving your Windsor business to a VoIP phone system takes four clear steps, from the line audit to ongoing support, and our team handles each one with you.
Line and number audit
We list your numbers, lines and handsets, plus anything else still running on copper, such as intruder alarms, lift emergency phones and card terminals, so nothing is missed when the old lines are switched off.
Design and quote
We map who answers which calls, design your call menus, queues and closed-hours routing, and send a written quote, with Teams calling, call recording and call reports included if you want them.
Port and install
We order the number port, set up desk handsets and apps, and show your staff how to use them before the switch happens.
Support and changes
Your staff call one Windsor number for new users, menu changes or faults, and we keep your setup up to date as you grow.
Frequently asked questions
VoIP Phone Questions From Windsor Businesses
Can I keep my 01753 number if we move?
Yes, in most cases. We port your existing 01753 numbers from your current provider to the new system, so customers keep dialling the same number. A few numbers on older or specialist services need extra checks, and we confirm each one before you commit.
What does the PSTN switch-off mean for us?
Openreach aims to close the analogue PSTN and ISDN network by January 2027. Any phones, alarms or card machines still on copper must move to a digital line first.
Can staff take office calls when at home?
Yes. Your team uses the business number on a desk phone, laptop or the mobile app, so calls follow them from the office to home or a client site, and outgoing calls show your 01753 number.
Do I need new desk phones?
Not always. Some existing handsets work with a cloud system, but older analogue and ISDN phones do not. We check your current kit during the audit, and many staff choose the desktop or mobile app in place of a handset on their desk.
What internet connection does the phone system need?
A stable business broadband line or leased line with enough upload for your busiest hour of calls. Each call uses little bandwidth but needs a steady connection, so we test yours first.
What about alarm and card lines?
They need checking before the switch-off. Many alarms, lift phones and older card terminals in Windsor still dial out over copper. We list each one and help move it to digital or 4G.
Does it work with Microsoft Teams?
Yes. We can connect your business numbers to Microsoft Teams so staff make and take external calls in the Teams app on a laptop or mobile. Anyone who prefers a handset can have one.
What happens if the internet goes down?
Calls still reach you. The system runs in the cloud, so if your office connection fails, calls divert to mobiles or another site, and staff can answer on the mobile app over 4G or 5G. We can also add a backup connection for the office line.
