New system, new hardware bill
Plenty of phone systems only work with their own handsets, so a switch quietly turns into a hardware purchase for every desk.
Integrations
Switch to Voxbi, keep your desk phones
Voxbi speaks SIP, the open standard that IP phones and softphones already use, so the desk phones, cordless handsets, and conference units you own keep working. Bring your own phones: reuse the hardware you have, mix brands and price points, and add softphones alongside, without replacing a thing.
- Any SIP-compliant phone
- Mix brands and softphones
- Config pushes from one dashboard
Switching systems shouldn't mean binning your phones
Locked to one brand
Proprietary systems tie you to a single vendor's phones, so you can't mix models to fit different roles or budgets.
Reconfiguring every handset
Without central provisioning, each phone is set up by hand, and every later change means another round of desk visits.
How the setup works
-
The phone registers
A SIP phone sends its username and password to Voxbi over the internet, no physical phone line involved.
-
Voxbi verifies it
Voxbi checks the account, applies your dial rules, and confirms the registration instantly.
-
Calls route over IP
Audio travels as data packets over your internet connection, so the phone works wherever it can reach the network.
-
Config stays central
Changes made in Voxbi push to every phone automatically. No more setting handsets up one desk at a time.
What SIP compatibility gets you
Reuse the phones you own
Any SIP-compliant handset registers with Voxbi and starts making calls in minutes, so existing hardware carries straight over.
Mix brands and price points
Put premium handsets at reception and budget models elsewhere. SIP is the common language, so brands and models mix freely.
Desk, cordless, and softphone side by side
Run desk phones for some, the Voxbi apps for others, and SIP DECT for people on the move, all on one system.
Bridge older analog phones
An ATA adapter brings legacy analog handsets into Voxbi, so a phone that still works doesn't have to be retired.
Scale one to a thousand
Add extensions as you grow, from a single handset to a thousand, without changing how the phones connect.
Great audio through the apps
Voxbi's own desktop and mobile apps are the softphone backbone, supporting high-quality Bluetooth and USB audio devices.
If it speaks SIP, it works
SIP is an open standard, so Voxbi supports desk phones, cordless DECT handsets, conference units, and softphones from a wide range of manufacturers. The Voxbi supported devices page lists the specific models tested for reliable performance.
Voxbi's own desktop and mobile apps double as the softphone layer for anyone without a desk phone, connecting Bluetooth or USB headsets for clear audio on every call.
Frequently asked questions
Will my existing desk phones work with Voxbi?
If they're SIP-compliant, yes. Voxbi uses the open SIP standard, so most modern IP desk phones register and start making calls without new hardware.
Do I have to buy new phones to switch?
No. Reusing your current SIP phones is the whole idea. You can keep what you have, add softphones through the Voxbi apps, and buy new handsets only if and when you want to.
Can I mix different phone brands?
Yes. Because every phone speaks SIP, you can run different brands and models together, choosing each to fit the role and budget.
Which specific models are tested?
The Voxbi supported devices page lists the desk phones, cordless handsets, and conference systems tested for reliable performance. Other SIP devices are supported too.
What about old analog phones?
An ATA (analog telephone adapter) bridges analog handsets into Voxbi over SIP, so a working phone doesn't have to be replaced.
