Desk phones tie people to a desk
Hardware has to be bought, cabled, and replaced, and it only works where it is plugged in. The moment someone works from home or travels, the office number stops following them.
Your business phone, on every device you already own
The Voxbi apps turn the devices your team already has into one business phone. Sign in once and the same extension rings in a browser tab, on the Windows or macOS desktop, and on iOS and Android, all carrying your business number. Calls run over the internet, so there is no desk phone to buy and no personal number to hand out.
- Tens of thousands of people take business calls on Voxbi
- Hosted in the EU
- GDPR & EU AI Act ready
Why staying reachable usually means juggling devices
Mobile calls expose personal numbers
When staff take work calls on their own phone, clients save the private mobile and call it directly. The business loses the call record, and the number walks out the door when the person leaves.
Every new starter waits on hardware
Onboarding a hire means ordering a phone and waiting for it to ship, and offboarding means chasing the device back. Provisioning a line should be a setting you change, not a logistics task.
How it works
-
Install the app and sign in once
Download the Voxbi app on a laptop, desktop, or phone, or just open it in a browser tab. One sign-in connects the device to your cloud PBX. No special hardware needed.
-
Every device registers to your PBX
Each app stays connected and ready to ring. You decide from the dashboard which devices ring together, so a desktop and a mobile can answer the same extension.
-
Calls carry your business identity
Incoming calls show the business caller ID, and outbound calls display your office number. The personal mobile number stays private on every call, on Wi-Fi or mobile data.
-
Full call control on any device
Transfer, hold, conference, voicemail, the company directory, and presence work the same everywhere. Answer on whichever device is closest and the rest stop ringing instantly.
What the Voxbi apps do
One identity everywhere
Browser, Windows, macOS, iOS, and Android all run the same extension. Sign in once and your number, contacts, and settings follow you to whichever device you pick up.
Ring every device at once
A call to your number can ring desk phone, desktop, and mobile together. The first device to answer takes the call and the others stop ringing, with no manual handoff.
Keep personal numbers private
Outbound calls from the mobile app show your business number, not the staff member's personal one. The business keeps the relationship and the call history, wherever the call is taken.
Full call control in the app
Dial, answer, transfer, hold, conference, and voicemail all live in the app, exactly like a desk phone. Nothing is left behind when someone leaves their desk.
Company directory and presence
See who is available before you transfer, reach colleagues from the shared directory, and set your own status so calls only ring you when you can answer.
HD voice over any connection
Calls use modern HD codecs over Wi-Fi, 4G, or 5G, so quality holds up in the office and in the field. A headset is all the extra kit anyone needs.
Why apps beat dedicated hardware
Putting the phone in software changes the economics and the reach of your phone system.
-
No hardware to buy
There are no desk phones to purchase or replace, and no cabling or PoE switches to maintain. A device your team already owns plus a headset is the whole kit.
-
Work from anywhere
Remote and travelling staff stay reachable on the office number across the EU. The same extension works from home, on the road, or at a second site.
-
Provision in minutes, not weeks
A new hire is an app install and a sign-in, not a hardware order. When someone leaves, you revoke their access instantly from the dashboard and the line goes with them.
Why teams put their phone in the Voxbi apps
Most cloud PBXs offer an app. The difference is the reach you get, what it runs on, and where the data sits.
A typical cloud PBX Voxbi
Where it runs A desktop app, or web only Browser, Windows, macOS, iOS, and Android on one extension
Hardware Their handsets, or softphone only Your existing Yealink, Snom, or any SIP desk phone, plus the apps
Mobile calling Forwarding that leaks the personal number Business caller ID on the mobile, personal number stays private
Provisioning Order hardware and wait Install, sign in, and revoke access from the dashboard
Hosting Often US-based cloud Hosted in the EU under GDPR and the EU AI Act
What teams say after the switch.
Voxbi is very user-friendly for end users, while still letting us implement more advanced configurations centrally.
We have been able to expand across the entire European Union and even internationally without ever worrying about communication costs or technical constraints.
What to look for in business calling apps
Decide provider-built or bring your own
Some apps are built and supported by the PBX vendor; others are standalone SIP clients you point at any system. Voxbi ships its own apps and also works with standard SIP softphones, so you are not locked into one client.
Test call quality on mobile data
Try the app on 4G and 5G, not only Wi-Fi, and ask about HD codec support such as Opus. Poor codecs are where mobile call quality falls apart in the field.
Demand desktop and mobile parity
Transfer, hold, conference, and voicemail should behave the same on every device. Staff should not relearn the app or lose a feature mid-call when they switch from desktop to phone.
Require encrypted calls and EU hosting
Look for TLS on signalling and SRTP on audio, and confirm where the platform runs. Voxbi encrypts calls and is hosted in the EU under GDPR and the EU AI Act, so call data stays in Europe.
Frequently asked questions
Do I need special equipment to use the apps?
No. A device your team already owns is enough: a laptop, desktop, or smartphone running the Voxbi app, or just a browser tab. A headset with a microphone improves comfort on longer calls but is not required.
Can one person use the app on several devices at once?
Yes. A single extension can ring on a desktop and a mobile at the same time. The first device to answer takes the call and the others stop ringing instantly, with no manual action.
Will callers see my personal mobile number?
No. Calls made from the mobile app show your business number, not your personal one, on Wi-Fi and on mobile data. The business keeps the call record and the client relationship.
Do the apps work abroad?
Yes, anywhere there is an internet connection. Calls run over Wi-Fi, 4G, or 5G, so the same extension works while travelling inside or outside the EU. Roaming charges do not apply to the call itself.
What happens if I lose or change my phone?
Your number and settings live in the cloud PBX, not on the device. Install the app on a new phone, sign in, and everything is restored. There is no SIM transfer or number porting to do.
Which platforms do the apps run on?
The Voxbi apps run in a web browser on any computer, as a Windows and macOS desktop app, and as native iOS and Android apps. Standard SIP softphones can also connect if you prefer a third-party client.
Are calls from the apps secure?
Yes. Voxbi encrypts signalling with TLS and audio with SRTP, and the platform is hosted in the EU under GDPR and the EU AI Act, so call data stays in Europe.
How fast can I add or remove a user?
In minutes. Adding a user is an app install and a sign-in rather than a hardware order, and removing one is a single change in the dashboard that revokes their access immediately.
