Teams stops at the meeting
On its own, Microsoft Teams has no phone numbers, no call routing, and no connection to the public telephone network. Customers can't call it.
Integrations
Real phone calls, right inside Microsoft Teams
Teams handles chat and meetings, but not phone lines. Voxbi adds that layer through Microsoft Direct Routing: your team makes and receives real calls on your business numbers inside Teams, on every signed-in device, while Voxbi handles the numbers, routing, and the public network behind it.
- Microsoft Direct Routing
- Keep your business numbers
- Hosted in the EU
Why Teams alone doesn't cut it for calls
A second app nobody opens
Your team lives in Teams all day, so a separate phone app gets ignored, and calls get missed or answered late.
Two systems to administer
A phone system next to Teams means two user directories to keep in sync and two places for IT to manage every joiner and leaver.
How the setup works
-
Check your Microsoft licenses
Direct Routing needs the Teams Phone license, included in Microsoft 365 E5 or added to other plans. We help you check what you have and what's missing.
-
We connect Teams to Voxbi
Voxbi links your Teams tenant to the phone network through a session border controller we run and manage. There is no telephony infrastructure for your IT team to build.
-
Your numbers ring in Teams
Users get their business numbers inside Teams. Calls ring on every device they're signed into, and outbound calls show your company caller ID.
What calling in Teams gets you
Real calls in the Teams app
Make and receive external calls on your business numbers without leaving Teams, on desktop, mobile, or in the browser.
Routing and queues preserved
Voxbi's call flows keep working behind Teams: menus, queues, schedules, and routing rules apply to every call as before.
Presence-aware colleagues
The Voxbi app runs natively inside Teams, with automatic Microsoft sign-in, and shows who is at work, on a call, driving, or at lunch, with one-click calling from the board.
Recording for compliance
Record the calls your industry requires you to, stored securely in the EU, even when they happen in Teams.
Legacy devices included
Doorbells, paging systems, and barriers connect into the same system, so the warehouse gate and the Teams call share one setup.
One place to administer
Numbers, users, and routing are managed centrally in Voxbi, so IT stops maintaining a phone directory next to the Microsoft one.
What changes for your team
Teams becomes the phone interface. Voxbi stays the phone system: numbers, routing, and the public network, managed in one place.
-
One app for everything
Chat, meetings, files, and now calls in the same window. No second softphone to install, learn, or forget to open.
-
Keep your numbers
Your existing business numbers move with you. Customers dial the number they always have, and it rings in Teams.
-
Remote staff, office number
A colleague working from home shares the same queues and numbers as the office, and customers never notice the difference.
What you need on the Microsoft side
Direct Routing requires a Microsoft 365 subscription with the Teams Phone license. It is part of an E5 plan and can be added to E1 or E3 plans as an add-on. Licensing can be confusing, and we walk you through exactly what your tenant needs before anything is ordered.
The session border controller that links Teams to the telephone network is run and managed by Voxbi. Your IT team keeps working in the Microsoft admin tools they know, with no telephony infrastructure to operate.
What to weigh up when adding calling to Teams
Direct Routing, managed
A telecom operator connects Teams to the public network and runs the infrastructure. The most flexible path on carrier choice, countries, and cost.
Operator Connect
Numbers assigned inside the Teams admin center, but with an aggregation layer between you and the operator that can add cost and constraints.
Microsoft Calling Plans
Numbers and billing from Microsoft directly. Simple, but coverage is limited in Luxembourg and pricing follows Microsoft's terms.
Local numbers across borders
For teams in Luxembourg, Belgium, Germany, and France, check local number availability and portability in every country, not just headquarters.
Frequently asked questions
Does this replace Microsoft Teams?
No. Your team keeps using Teams exactly as before for chat, meetings, and files. Voxbi adds the calling layer on top, running in the background.
Which Microsoft licenses do we need?
A Microsoft 365 subscription with the Teams Phone license. It is part of an E5 plan and can be added to E1 or E3 plans as an add-on. We check your tenant's licensing with you before setup.
Can we keep our existing phone numbers?
In most cases, yes. Voxbi supports number portability in more than 25 countries, so multi-site and cross-border teams can keep local, national, and international numbers while running everything through Teams.
Do we have to set up Direct Routing ourselves?
Only if you want to. Voxbi's Microsoft-certified engineers can guide your team step by step, or run the whole thing as a managed service, licensing, Teams Phone configuration, and ongoing monitoring included.
Why Direct Routing instead of Operator Connect?
Both need the same Microsoft licenses. Operator Connect adds an aggregation platform between you and the operator, which can add cost and limits. Managed Direct Routing offers the same ease with more flexibility on carriers, countries, and pricing.
Can remote employees use the office number?
Yes. Numbers live in Voxbi, not in a desk phone, so anyone signed into Teams can share the office number and its call queues from anywhere.
What happens if the internet goes down?
Teams calls need connectivity. Voxbi's routing rules can also ring a mobile number, so you can set incoming calls to fall back to mobiles and keep callers connected.
