Looking for a telephony platform that grows with your business? Then you’ve just found it! With our all-in-one platform you choose yourself where your calls land, and you adjust that at any time in real time, so your organisation stays perfectly reachable.
You decide how we deliver your calls. Over VoIP, through a fixed number on your mobile, or forwarded to your existing telephony setup or your SaaS tool — whatever suits the way you work, and you switch between them in a few clicks.
Under your business number you freely combine different devices. A desk phone at the office, a softphone on your laptop for those working from home or hybrid, and your fixed number on your mobile for when you’re on the road, keeping your private number private.
You manage your whole system yourself in the browser. Change destinations and forwarding, set opening hours, holidays and voicemail, and view your call activity — changes take effect immediately, without waiting for a technician.
Working in a team? In the dashboard you see who’s available and who’s on a call. Incoming calls go to the right colleague, and shared queues make sure customers aren’t left waiting.
All of this runs on our own platform, which we built ourselves. We’re not a reseller, so we don’t depend on third parties and you get the newest features fast. That’s how we combine the stability of the fixed network with the freedom of the cloud.
One platform for your single business number, or for extra numbers at home and abroad, forwarded to your existing system or to new devices — and you keep all of it in your own hands, online and in real time. Request your number and we’ll get to work for you.

One team, three delivery routes. The device decides which one it uses.
VoIP desk phones, or a softphone app, or forwarding to mobile: pick a provider and you have usually picked one of those for good. Our platform routes the same call over any of them, so the device decides, not the contract. Three things follow.
A desk phone sits on the office network, where VoIP is at its most reliable, because the phone and the connection are in the same building. A mobile takes the call over the mobile network, with no app and no data, while a laptop uses VoIP wherever it happens to be.
All of them in the same team, on the same number, under the same routing rules.
When the office line goes down, the VoIP devices go down with it. A mobile in the same team does not, because it never needed the internet in the first place, so adding one as a fallback keeps the number ringing.
This is the reason to mix, and the one nobody thinks about until the Tuesday it happens.
Put a desk phone, a laptop and a mobile in front of the same person and it is still one person. Charging per device would make a hybrid setup pointless, so we do not.
Start on a mobile with no hardware at all, add a desk phone when the office fills up, and nothing has to be migrated.
It is nobody’s fault and it will be fixed by the afternoon. The question is what your number does in the meantime.
Nobody uses all five on day one. Most teams start with two and add a third when something changes.
A handset on the desk, plugged into the office network. The most reliable VoIP option there is, because the phone and the internet connection are in the same building.
Your business line on a laptop, with a headset. Linphone, the open-source softphone, runs on Mac or Windows, so a computer becomes a full business phone.
Calls routed to an ordinary mobile over the mobile network. No app to install, no data connection needed, and the private number stays private.
A shared screen showing who is free, who is on a call, and what is waiting. For the moment several people share one number and need to see the same thing.
The control panel for all of it. Destinations, routing, opening hours, holidays, recordings and statistics are changed from the browser and live immediately.
Everything below happens in the browser. None of it needs an engineer or a support ticket.
A mobile, a laptop, a handset: whatever people actually use. Nothing has to be bought first, because a mobile number is a valid device on day one.
One after another, round robin, or all at once. Set how long each device rings, when the team is open, and what happens outside those hours.
Somebody off sick, a new starter, a bank holiday, a temporary diversion to a mobile. You edit it and the next call follows the new rule.
You can start today with nothing but the phone in your pocket, and in most cases bring your existing number with you. The same platform runs a one-person setup and a contact centre with hundreds of agents, so adding a support line, a second country or ten more people later is a change of settings rather than a migration.
Every device here is good at something and bad at something else. Choosing well is mostly about being honest about where people actually are when the phone rings.
A desk phone is the right answer for anyone who sits in the same chair all day and takes calls constantly, such as reception, a sales desk or a service line. It is also the most reliable VoIP device you can have, because the handset and the internet connection are in the same building and nothing else is in the way.
A softphone suits people who work from a laptop anyway, and it costs nothing to try. Its quality is the quality of the connection it is sitting on, which is excellent at a desk with fibre and less predictable on hotel wifi. That is not a criticism of the software; it is what running voice over the internet means.
A mobile is the odd one out, and the reason to have one in every team. It takes the call over the mobile network rather than the internet, so it keeps working when the office line does not, needs no app on somebody’s personal phone, and reaches people who are nowhere near a desk. Put one at the end of the ring order and most of the failure modes above stop mattering.
If you are not sure, start with mobiles only. It costs nothing, it works everywhere, and you can add handsets once you know where the calls actually land.
Tell us who needs to be reachable and where they are when the phone rings. We will put the team together, port your number if you have one, and you can change every rule yourself afterwards from the browser.
Your calls travel over traditional fixed carrier networks rather than the cheapest internet route, so callers hear the clarity of a domestic landline even across borders.
CallFactory is a registered telecom operator in 14 of the largest European countries and runs its own platform. Special routing or an urgent change is handled directly by us.
Different kinds of device under one business number: desk phones, mobiles, softphones and the web tools, all in the same team with the same routing. The call is routed over VoIP, the mobile network or the fixed network depending on which device is answering.
Yes. CallFactory’s phone system is designed to mix devices freely. Office staff can use desk phones, remote workers can use softphones, and team members on the go can receive calls on their mobile, all under the same number with the same routing rules.
You define the routing from your dashboard. Choose sequential forwarding (ring one device after another), round robin (rotate between team members), or simultaneous ringing (all devices ring at once). You can also set business hours, IVR menus, and fallback destinations.
Not necessarily. You can start with fixed on mobile (calls forwarded to your existing mobile phone) or a softphone on your laptop, and neither requires any hardware investment. If you want desk phones, we recommend the Ubiquiti UniFi G3 series, purchased directly from the manufacturer or a reseller.
In most cases, yes. You can port your existing business number to CallFactory and continue using it within the new phone system. This lets you upgrade your setup without changing contact details.
Everything is managed from the web interface, which is a single dashboard in your browser. Add phone numbers, configure routing, manage devices, download softphone licences, and review call statistics. Changes take effect immediately.
Yes. The platform scales from a single phone number forwarding to one mobile, all the way to contact centres with hundreds of agents. Start simple and expand as your team grows, with no migration needed.
Desk phones and softphones need a working internet connection. If internet reliability is a concern, add a mobile phone as a fallback destination. Fixed on mobile routes calls over the mobile network and works regardless of internet or power outages.
