Microsoft Teams already handles calls, chat, and meetings for your whole company. Turning it into a real contact center means adding queues, routing, omnichannel, and reporting on top. How you add that layer decides one thing that matters more than any feature list: whether the call stays inside your Teams tenant or gets pulled out to another platform.
Teams on its own gives you auto attendant and call queues. That is fine for a small internal help line, but it is not a contact center. To get skills-based routing, omnichannel, and real reporting, you integrate a certified contact center. The decision that shapes everything else is architectural. Does the provider keep the call inside your Microsoft tenant, or route it out to their own cloud? The genuinely native answer is the Extend model, where the provider directs the call but the media never leaves Teams. Luware Nimbus is the Extend-native platform we implement, delivered and managed through our partner Momentum.
Teams Phone is a strong business phone system. With Teams Phone you get auto attendants and call queues, so a caller can press 1 for sales and land in a small group. What you do not get is the machinery a support or sales operation runs on: skills-based and priority routing, queue callbacks, real-time wallboards, historical reporting, quality management, and channels beyond voice such as web chat, email, and social.
A contact center for Teams adds that machinery. Microsoft runs a certification program so the providers that plug in meet its quality and reliability bar, and it defines three ways they can connect. The models are not just packaging. They decide where your calls physically live, how your agents work, and how your data stays compliant.
Microsoft certifies three models for connecting a contact center to Teams. The plain-English difference is where the call and its media end up.
| Model | How it connects | Where the call & media live | Native to Teams? |
|---|---|---|---|
| Connect | Certified session border controllers and Direct Routing bridge the provider's own contact center to Teams. | The call is routed out to the provider's cloud. Agents often work in a separate app next to Teams. | No. Integrated, but the call leaves Teams. |
| Extend Native | The provider uses the Microsoft Graph Cloud Communications APIs to direct calls without ever taking them over. | The call and media stay inside your Teams tenant. Agents answer in the Teams client they already use. | Yes. This is the native model. |
| Unify (Power) | The provider builds on Azure Communication Services to create a new, tightly coupled CCaaS app. | Calls run on Azure Communication Services infrastructure rather than the Teams calling stack. | Partly. Microsoft-cloud based, but a separate app, not the Teams client. |
Most of the big names you already know, such as Five9, Genesys, and NICE, connect through the Connect or Unify models. They are excellent platforms, but they run the contact center in their own cloud and treat Teams as a connected phone system. The Extend model is the one where Teams is the contact center. That is the distinction buyers mean when they ask for something native.
There is a second, separate question that often gets tangled up with the integration model: how do outside phone numbers reach Teams in the first place? This is the PSTN layer, and it is independent of which contact center you choose. Any of these can sit underneath a native Extend contact center.
Pick a participating carrier straight from the Teams admin center. They provision your numbers and manage the trunk. No session border controller for you to run, and fast to stand up.
Connect your own or a partner's SIP trunk through a certified SBC. More control over carriers, porting, and least-cost routing, in exchange for more to configure and manage.
Buy minutes and numbers directly from Microsoft as an add-on license. Simplest to buy, though it is not available everywhere and can cost more at scale.
The phrase people search for, native Operator Connect contact center, is really two good ideas stacked together. Operator Connect (or Direct Routing) brings the numbers into Teams, and the Extend model keeps the resulting call inside Teams. Put together, the call is born in Teams and never leaves it.
Calls, recordings, and customer data remain in your Microsoft environment, which keeps GDPR and HIPAA conversations simple and avoids handing media to a third-party cloud.
Agents answer, transfer, and collaborate in the Teams client they already live in. No second softphone, no swivel-chair between two apps.
With Operator Connect underneath, there is no session border controller or extra voice infrastructure for your team to buy, patch, and babysit.
Teams presence, the full company directory, and one-click expert transfers are native, so agents can pull in a back-office colleague without leaving the call flow.
Because it rides on the Teams you already run, a native contact center can go live in days rather than the multi-month cutover a rip-and-replace platform demands.
Voice quality, identity, and collaboration all stay on Microsoft's stack, so you are not refereeing finger-pointing between a separate CCaaS carrier and Microsoft when a call sounds bad.
Luware Nimbus is a contact center built on the Extend model, so it runs natively inside Microsoft Teams. Luware was an early mover on Teams-native contact center and is Microsoft certified. When we place a Teams-first client on a native contact center, Nimbus is the platform we use, and it is delivered and managed as a service through our partner Momentum, so you get a single point of accountability for licensing, PSTN, and support.
Voice, web chat, and email routed to agents in the Teams client, with skills-based routing, queues, and callbacks.
A full receptionist and operator console for high-volume call handling, with presence-aware transfers across the directory.
Self-service and agent assist built with Azure and Copilot Studio, so routine questions are deflected before they reach a person.
Real-time dashboards and historical reporting on queues, agents, and service levels, with data staying in your Microsoft tenant.
Start with a light attendant or routing tier and add full contact center and AI modules per user as teams grow.
Momentum handles design, provisioning, PSTN, and ongoing support as one managed service, so it is not another platform for your IT team to own alone.
If your company already runs on Microsoft 365 and Teams Phone, a native contact center is almost always the cleaner path than bolting on a separate CCaaS cloud. We deploy Luware Nimbus via Momentum for exactly this. If Teams is not your center of gravity, or you need a heavy outbound dialer or the deepest omnichannel suite, a best-of-breed platform may fit better, and we will tell you so. Get an estimate and we will map it to your setup.
A Teams contact center is priced in three stacked layers, and it helps to see them separately:
Your Microsoft 365 plan plus a Teams Phone license for each agent who handles calls. Many organizations already own most of this.
Operator Connect, Direct Routing, or a Microsoft Calling Plan to bring outside numbers in. Priced by numbers and minutes.
The Nimbus license, per user per month. A light attendant or routing seat is inexpensive; a full omnichannel or AI seat costs more.
Because so much depends on how many of those layers you already own and which modules each agent needs, a per-seat sticker number in isolation is misleading. That is what the estimator is for. See how CCaaS pricing works for the wider market, then get a scoped number for a Teams-native build.
Teams Phone includes auto attendant and call queues, which cover a basic internal help line. It is not a full contact center on its own. For skills-based routing, omnichannel, wallboards, and reporting you add a certified contact center that integrates with Teams through one of three Microsoft models: Connect, Extend, or Unify.
A native Teams contact center uses the Extend integration model. The provider orchestrates routing through the Microsoft Graph Cloud Communications APIs, but the call and its media stay inside your Teams tenant and agents answer in the Teams client. Connect and Unify models route the call out to the provider's own cloud, so they integrate with Teams without being native to it.
No. A small group of providers build on the native Extend model, but most large CCaaS platforms integrate through the Connect model, which takes the call out of Teams, or the newer Unify model, a separate Azure Communication Services app. Luware Nimbus is an Extend-certified, Teams-native platform, and it is the option we deploy and manage through our partner Momentum.
Both bring outside phone numbers into Teams. Operator Connect lets you pick a carrier from the Teams admin center and have them provision numbers with no session border controller to manage. Direct Routing connects your own or a partner's SIP trunk through a certified SBC, which gives more control at the cost of more setup. Either one can sit under a native Extend contact center.
You pay for three layers: your Microsoft 365 and Teams Phone licensing, a PSTN option (Operator Connect, Direct Routing, or a Calling Plan), and the contact center software itself, priced per user per month. A light attendant-console seat costs far less than a full omnichannel contact center seat. An advisor can size the total for your headcount and channel mix.
An independent advisor scopes a Teams-native build against the alternatives that match your channels, volume, and licensing. Free, no vendor bias.
