Microsoft Teams phone system with TDS as your carrier
TDS TeamMate turns Microsoft Teams into your business phone system. It connects Microsoft Teams to the TDS Hosted VoIP platform through Operator Connect, so your team keeps Teams as its phone app while TDS supplies the numbers, the dial tone and the support. No Microsoft Calling Plan needed.
Teams becomes the phone. TDS runs the calls.
Microsoft Teams can make and take outside calls, but Microsoft has to get those calls from a carrier. TDS TeamMate makes TDS that carrier. Your numbers, your minutes and your support come from TeleData Services, and your people never leave Teams.
No Microsoft Calling Plan needed
TDS supplies the numbers and the calling. You keep your Teams Phone license from Microsoft and skip the per-user Calling Plan.
Keep your numbers and your desk phones
Bring your existing numbers. Staff who need a desk phone, paging, fax or an analog line stay on TDS Hosted VoIP in the same tenant.
One bill, one support team
Teams users, desk phones, SIP trunks and an on-premise PBX can all live under one Microsoft tenant with TDS supporting the whole thing.
Dial tone inside the app your staff already live in
TeamMate connects TDS Hosted VoIP to Microsoft Teams through Operator Connect, so the Teams dial pad places and receives real business calls on your TDS numbers.
- Calls on your existing TDS numbers
- Works on desktop, mobile and Teams certified phones
- No separate softphone to install
- Set up from the Teams admin center
Built for Microsoft 365 shops and TDS Hosted VoIP customers
Companies standardized on Microsoft 365
You already run email, files and meetings in Microsoft 365. TeamMate retires the separate phone system and puts calling where your people already are.
TDS Hosted VoIP customers adding Teams
Give the back office Teams calling without giving up what the front office relies on: desk phones, call queues, paging, fax and analog devices.
Hybrid and multi-site teams
One number follows each person across the Teams desktop app, mobile app and a desk phone, in the office or at home.
Two ways to connect Teams to TDS
Operator Connect Express is the default. Your TDS numbers appear in the Teams Admin Center as an operator, and your admins assign them the way they already assign everything else in Teams. Direct Routing as a Service is the alternative when you would rather have TDS manage routing from our portal.
- Yes
- Yes
- Permissions required
- Not required
Why Operator Connect Express is the default
Fast setup
Basic SIP trunk interoperation instead of a lengthy certification program, so the connection is configured in hours and you are live in days.
Managed in the Teams Admin Center
Numbers and users are assigned where your admins already work. Hybrid users who also have a desk phone appear in the TDS portal as well.
No SBC hardware
No session border controllers to buy, host or maintain, physical or virtual. TDS carries that on our side.
Bulk provisioning
Upload and provision phone numbers in bulk, or automate it through the platform API.
What you get in a Microsoft Teams phone system from TDS
Keep your numbers
Your existing TDS numbers, and numbers you port in, ring in Teams. No renumbering, no new business cards.
Manage it where you already work
Numbers, dial plans and calling policies live in the Teams Admin Center. No Global Administrator role is needed day to day.
Live in days, not months
Connecting your tenant is basic SIP interop, not a certification project. Setup is scoped and quoted with your seat count.
Hybrid by design
Teams users, TDS Hosted VoIP desk phones, SIP trunks and an on-premise PBX can share one Microsoft tenant. One bill, one support team.
No hardware to buy or run
Session border controllers run in Microsoft Azure, not in your closet. Nothing to rack, patch or replace.
Grows with you
Add numbers in bulk or by API as you hire, and move users between Teams and desk phones without a project.

Not on Teams? TDS AI Voice Agents does the same job on the TDS Hosted VoIP platform.
From your Teams tenant to dial tone
1. Review your tenant
We check your Teams Phone licensing, list the numbers to keep and decide who needs a desk phone alongside Teams.
2. Connect TDS to Teams
We set TDS up as your operator in the Teams Admin Center, or configure Direct Routing if you prefer TDS to manage it.
3. Port and assign numbers
Existing numbers port to TDS and are assigned to users and groups. Desk phones go on TDS Hosted VoIP in the same tenant.
4. Support from one team
TDS supports the connection, the numbers and the call quality. One help desk for Teams calling and desk phones alike.
Live in days, not a migration project
TeamMate is enabled per user from the Teams admin center. Pilot it with one department, keep desk phones where they make sense, and move the rest when you are ready.

Microsoft Teams phone system: what buyers ask first
Do I need a Microsoft Calling Plan?
No. TDS supplies the numbers and the calling. Each user still needs Microsoft’s Teams Phone license, which is what lets Teams act as a phone. TeamMate replaces the Calling Plan, not the Phone license, so your Microsoft Teams phone system runs on TDS numbers.
What is Microsoft Teams Phone, and what does TDS TeamMate add?
Teams Phone is the Microsoft license that turns Teams into a phone: a dial pad, voicemail, call queues and auto attendants. It does not include phone numbers or a connection to the public phone network. TDS TeamMate adds that part: TDS becomes the carrier behind Teams through Operator Connect, supplies the numbers and the calling, and supports it from the same help desk that runs TDS Hosted VoIP.
Can Microsoft Teams be our whole business phone system?
For most office staff, yes. With Teams Phone and TDS TeamMate every user has a business number inside the Teams desktop and mobile apps, so Teams works as the whole Microsoft Teams phone system for the office. Reception, warehouse, paging, fax and analog devices stay on TDS Hosted VoIP desk phones in the same tenant, so the whole building is one system with one bill and one support team.
Can I keep my phone numbers?
Yes. Both connection models bring your own numbers. We handle the port and schedule the cutover so there is no gap.
Who supports it?
TDS. The connection, the numbers and the call quality of your Microsoft Teams phone system are supported by the TeleData help desk, the same team that supports TDS Hosted VoIP.
What about desk phones, paging, fax and analog devices?
They stay on TDS Hosted VoIP inside the same Microsoft tenant. Front office on desk phones, back office in Teams, one bill and one support team.
How long does it take?
Days, not months. A Microsoft Teams phone system on Operator Connect Express needs only basic SIP interop on our side and shows up in your Teams Admin Center as an operator. Setup is scoped and quoted with your seat count.
Is this the same as TDS AI Voice Agents?
No. The AI Voice Agents add-on on this page runs on Microsoft Teams Phone. TDS AI Voice Agents is a separate product for the TDS Hosted VoIP platform, sold per agent in Starter, Pro and Elite tiers.
