Organizations have spent years building around Microsoft Teams, then buying a completely separate platform for customer service.
It’s not that the integrations don’t work. They do. But they come with tradeoffs like agents switching between apps, IT managing overlapping systems, and customer data that never quite connects with the rest of the business.
Microsoft’s Unify integration model changes the architecture. Rather than slapping a patchwork contact center onto Teams, it builds one directly into Microsoft’s cloud infrastructure, so internal collaboration and customer engagement finally share the same foundation.
Explore how the Unify model integrates with Teams, how it reshapes communication workflows, and what it means for teams already running on Microsoft’s stack.
How Teams contact center integration has worked until now
Microsoft has offered two main paths for connecting a contact center to Teams: the Connect model and the Extend model.
- Connect: A third-party contact center links to Teams through session border controllers and direct routing. Teams acts as the phone, but the vendor handles everything else: routing, reporting, and automation. It works, but the two systems stay separate under the hood.
- Extend: Uses Microsoft APIs to embed contact center features inside the Teams client so agents can handle calls without leaving the app. But the telephony still runs on the vendor’s infrastructure. Media and signaling are split between two environments.
Both models move the contact center toward Teams. Neither puts it inside Teams. That’s the gap the Unify model closes.
What the Unify model actually changes
The Unify model builds the contact center directly on Microsoft’s cloud infrastructure using Azure Communication Services. There’s no external telephony layer or split media streams. The contact center runs on the same platform as the rest of Teams.
The technical backbone is Teams Phone Extensibility (TPE). It opens up the native calling features of Teams Phone to contact center applications, which means:
- One telephony platform: Back-office employees and contact center agents share the same phone system. No parallel infrastructure to manage.
- Dual persona for agents: Agents keep their internal collaborator identity and their contact center identity in the same Teams client. The system routes calls to the right interface based on context.
- Media stays in Azure: Voice traffic doesn’t leave Microsoft’s environment. That means lower latency, tighter security, and native access to AI features like Copilot.
How the three models compare:
| Connect | Extend | Unify | |
|---|---|---|---|
| Infrastructure | External vendor cloud | Hybrid (vendor + Teams APIs) | Microsoft Azure |
| Agent experience | Separate app or Teams softphone | Embedded in Teams | Native inside Teams |
| Telephony | Vendor managed via SBCs | Vendor managed via direct routing | Teams Phone (TPE) |
| AI access | Vendor specific | API driven | Native Copilot and Azure AI |
Why this matters for IT teams
The technical shift is significant. But what IT leaders care about is what it does to their operations.
Fewer platforms to manage
When the contact center runs natively on Teams, there’s no second telephony stack to maintain. Licensing, dial plans, security policies, and compliance are consolidated into a single environment.
Agents stay in one place
No more switching between a collaboration tool and a contact center app. Everything lives in Teams. That reduces training time and speeds up handling.
AI is built in, not an afterthought
Because the Unify model runs on Azure, features like real-time transcription, sentiment analysis, and Copilot-generated call summaries are native to the experience. Agents get AI assistance without IT having to integrate a separate tool.
The early results are promising too. Luware reported an 80% reduction in after-call work through Copilot-powered summaries and a 44% improvement in call answer rates in case studies using their Teams-native platform.
How Momentum and Luware deliver the Unify experience
The Unify model sets the foundation. Momentum and Luware bring it to life.
Momentum’s Microsoft Teams contact center solution, powered by Luware, is built natively for Microsoft Teams. It handles the customer engagement layer using:
- Skill-based routing: Calls go to the most qualified agent based on language, expertise, or priority, not just the next person in line.
- Omnichannel support: Voice, chat, email, and social channels all managed from a single Teams interface.
- Drag-and-drop workflows: Service owners can customize call flows and IVR menus without needing developer resources.
- Built-in reporting: Real-time dashboards and Power BI templates give supervisors visibility into queue status, agent performance, and session volume.
Momentum provides the managed infrastructure underneath. That includes global voice connectivity through Operator Connect and Direct Routing, network redundancy across 200+ points of presence, ongoing operational support, and several premium addons to help you maximize your investment in Microsoft Teams.
The result is a fully embedded contact center inside Teams, delivered through one provider, one bill, and one team without vendor sprawl. There’s no piecing together separate contracts for voice, contact center software, and connectivity.

FAQs
What is the Microsoft Teams Unify model?
It’s Microsoft’s newest integration tier for Teams contact centers. Unlike older models that connect external platforms to Teams, Unify builds the contact center directly on Microsoft’s Azure infrastructure, so it runs natively inside Teams.
How is the Unify model different from Connect and Extend?
Connect links an external contact center to Teams through session border controllers. Extend embeds some features into the Teams client, but still relies on external telephony. Unify eliminates the external layer entirely. Everything runs on Microsoft’s cloud.
Do I need to replace my current contact center to use the Unify model?
Not necessarily. The right model depends on your current setup and where you’re headed. But if you’re already invested in Teams, Unify offers the most seamless path forward.
What is Teams Phone Extensibility?
Teams Phone Extensibility (TPE) is the technology that powers the Unify model. It lets contact center applications use the native calling features of Teams Phone, including PSTN connectivity, dial plans, and emergency calling, without a separate telephony stack.
Can I use the Unify model with my existing Teams Phone licenses?
Unify requires TPE-enabled Teams Phone plans. Your current licensing may already support it, but it’s worth reviewing with a partner like Momentum to confirm what’s needed.
