As more businesses ditch desk phones in favor of cloud-based voice, one thing is becoming clear: customers want calling that lives natively inside Teams.
After all, over 8 million U.S. businesses use Teams on a daily basis, including over 90 percent of Fortune 500 companies. Why not bring voice into a platform they’re already familiar with?
This shift to voice-enabled Teams has opened the door for MSPs to play a much bigger role in voice services, but only if the right tools are in place.
That’s where Microsoft Teams Operator Connect comes in.
If you’re an MSP thinking about adding Teams voice services to your offering, Operator Connect could be a game-changer. But there are a few things you’ll want to understand first, like:
- How it works
- What’s involved in deployment, and
- How platforms like TeamMate Operator Connect Express make the process a whole lot easier (and faster)
What Is Microsoft Teams Operator Connect?

Operator Connect is Microsoft’s way of making phone service in Teams feel simple for businesses. Instead of going through complex setups like Direct Routing, companies can connect to a voice provider (like you) directly from the Teams admin center in just a few clicks.
For the business, this means:
- Real phone calls inside Teams (PSTN calling)
- Local phone numbers and service from a provider they trust
- No extra apps or platforms to manage
For MSPs, it means:
- You get to be the trusted provider for Teams-native calling
- You avoid the infrastructure burden of Direct Routing
- You can offer voice services as part of a broader managed service stack
However, joining the Operator Connect program isn’t exactly plug-and-play. We’ll show you why.
A Look at the Standard Deployment Process (Without TeamMate)
If you’re planning to become a Microsoft Teams Operator Connect partner the traditional way, here’s what you’d typically be dealing with:
Step 1: Get Approved by Microsoft
First, you’ll apply to the Operator Connect Program. Microsoft checks that your network, support model, and service footprint meet their standards.
It’s important to note that approval isn’t instant, and sometimes not granted on the first try. If your infrastructure or coverage area needs work, you’ll need to make improvements before moving forward.
Step 2: Set Up the Infrastructure
Once approved, it’s time to build out your voice network. You’ll need Teams-certified SBCs, a connection to Azure, and a system that can handle call routing, number management, and failover. Everything needs to be reliable, redundant, and ready for scale.
Step 3: Connect to Microsoft’s Systems
Now you’ll integrate your platform with Microsoft’s APIs. This is how Teams will talk to your service so users can assign Teams phone numbers and enable calling. It’s a deep technical lift and requires solid dev resources to get right.
Step 4: Build a Customer Portal
Customers need an easy way to manage users, numbers, and settings. That means building a Teams-friendly portal that’s secure, intuitive, and kept up to date. Without it, your service becomes hard to support and harder to sell.
Step 5: Pass Microsoft’s Testing
Before launch, Microsoft will put your setup through a full test cycle. They’ll check for call reliability, compliance, number portability, and more. If something fails, it’s back to the drawing board for fixes and retesting.
Step 6: Stay Compliant and Keep It Running
Even after you’re live, the work continues. Microsoft’s systems and standards evolve, and your platform needs to keep pace. That means regular updates, ongoing support, and a long-term maintenance plan to keep everything aligned.
TL;DR? It’s a big investment that many MSPs simply don’t have the time or resources to manage. This is exactly why TeamMate built Operator Connect Express.
How TeamMate Makes Operator Connect Deployment Easier
TeamMate’s Operator Connect Express solves all the headaches above by handling the Microsoft side of the equation for you.
Rather than build everything from scratch, you use TeamMate’s pre-approved, ready-to-deploy platform to deliver voice services through Teams. It takes what would be a months-long process and gets you up and running in days.
Here’s how the rollout works:
You’re Onboarded as a Partner
TeamMate sets everything up behind the scenes. That includes your SIP routing, Microsoft Graph API integration, and your branded instance of the Connector App. You don’t have to worry about infrastructure, compliance, or integration details. It’s all handled for you.
You and Your Customers Get Access to the Portal
The TeamMate Connector App is where you manage it all. It’s simple, clean, and built for service providers. You (and your customers, if you choose) log in, connect a Microsoft 365 tenant, and you’re ready to assign phone numbers and activate users. No coding. No complicated workflows. Just a few clicks.
Customers Activate the Service in Teams
Once connected, your offering appears in the Microsoft Teams admin center. Customers can select your service, assign numbers to users, and start making calls without leaving Teams. No downloads, no extra apps, it just works.
You Manage Everything from One Place
The Connector App becomes your control center. You can provision new users, reassign numbers, and offer add-ons like call recording or Teams Chat. Everything happens in the same portal. It’s fast, flexible, and easy to support.
To sum up, TeamMate’s Operator Connect Express gives you a fully managed foundation, so you can focus on growing your voice business, increasing retention, and offering services your customers actually want.
