What Is Microsoft Operator Connect? A Plain-English Guide for SMBs

Your team is already in Teams all day, scheduling meetings, sharing files, chasing down threads. But the phone system they use is still its own separate thing with its own bill, own admin portal, and own set of headaches.

You may be wondering whether you can move calling into Teams and be done with it. The short answer is yes, but the how matters, and that's where most people get stuck.

If you've Googled it, you've seen three options thrown around: Microsoft Calling Plans, Direct Routing, and Operator Connect. The first two get most of the attention. Calling Plans are simple but limited. Direct Routing is powerful but complex. Operator Connect is somewhere in the middle, and it's the one most SMBs haven't heard of yet.

This guide breaks down what Operator Connect actually is, how it compares to the alternatives, what it costs, and how to tell if it's the right fit for your organization based on our experience deploying Teams Calling for over 100 organizations since 2020.

What is Microsoft Operator Connect?

Operator Connect is a Microsoft certification program that lets approved telecom carriers plug phone service directly into Teams. There’s no hardware to install, no session border controllers (SBCs) to configure, and no separate phone system to maintain.

To set up, Microsoft certifies a carrier (like Atlantech) and gives them a managed API connection into the Teams platform. The carrier handles the PSTN connection, which is the part that actually connects your calls to the outside world. You handle user management through the Teams Admin Center you're already using.

This way, Teams becomes your complete phone system. Calls, meetings, chat, voicemail, all in one place.

If you've looked at Microsoft Teams Calling before and felt like the options were either "too simple" or "too complex," that's the gap Operator Connect was built to fill. It's not the only way to add calling to Teams, but for a lot of SMBs, it's the easiest one to get up and running without bringing in a full-blown telecom project.

How Operator Connect Compares to the Other Two Options

Operator Connect isn't the only way to add calling to Teams. There are three options total, and they differ in who manages what, how much setup is involved, and how much control you get.

* With Atlantech's Direct Routing as a Service (DRaaS), the SBC is managed on Atlantech's side, so you don't need to deploy or maintain one yourself.

There are a few things worth mentioning:

Calling Plans are the most hands-off option. Microsoft handles everything, including the carrier side. That sounds appealing until you realize you're locked into Microsoft's rates, their support timelines, and a fairly rigid feature set. For companies with straightforward, low-volume calling needs, it works fine. For most others, this will feel limiting.

Direct Routing is the most flexible option, but it comes with a lot of overhead. You need a session border controller, someone to manage it, and a more involved setup process. The big upside is survivability. If Teams goes down, your SBC can fail over and keep calls running. If your organization treats phone uptime as non-negotiable, Direct Routing is the stronger choice.

Operator Connect can be a happy medium. You get carrier-managed service and carrier-set pricing like Direct Routing, but without the hardware or complexity. The trade-off is that if Teams goes down, your phones go down with it. For most SMBs, Teams' 99.99% uptime SLA means that's a risk worth accepting, but it's worth knowing about before you commit.

Another thing to keep in mind is that Operator Connect doesn't support custom dial plans, SIP trunking, or GCC High environments. If any of those are on your requirements list, Direct Routing is the path you'll need to take.

What You Get with Operator Connect

Here's what's included when you go through a carrier like Atlantech.

Calling: Unlimited local and long-distance calling across the U.S. You can port your existing phone numbers over at no cost, so nothing changes for your customers or vendors.

Call management: Call queues, auto attendants, call recording, and call reporting are all built in. Atlantech also offers a Microsoft-certified attendant console that installs in about a minute for teams that need a dedicated receptionist-style view.

Call Manager tool: This is a free tool from Atlantech that lets you handle setup and ongoing management through a wizard-driven interface with role-based permissions and real-time monitoring. The big selling point here is that you don't need access to the Teams Admin Center to use it. This is useful if you want to delegate phone system management without handing over the keys to your entire Teams environment.

Business texting: atlantech|text lets your team send and receive SMS and MMS from your Teams phone number. It's a separate add-on, but worth knowing about if your staff communicates with clients or customers over text.

Security and reliability: Calls are encrypted with TLS 1.3, caller ID is verified through STIR/SHAKEN, and the whole thing runs on a Microsoft Certified integration backed by a 99.99% uptime SLA.

What It Costs

Under 500 users: $7 per user, per month. That's a flat rate that includes unlimited U.S. local and long-distance calling, number porting, the Call Manager tool, and 24/7 support. No tiers, no per-minute charges.

500+ users: Atlantech offers a shared channel model at $5 per number per month plus $20 per simultaneous call path. Most organizations at this size don't need a 1:1 ratio of users to call paths, so the savings add up. Typical savings run 30-50% compared to the flat-rate plan.

What's not included: Your Microsoft 365 licensing is separate from Atlantech, and you'll need a plan that includes Teams Phone. If your current M365 plan doesn't include it, that's a $10 per user per month add-on from Microsoft. International long-distance is pay-as-you-use, and atlantech|text is a separate add-on with its own pricing.

Atlantech is currently offering the first month free with no setup fees, no porting fees, and a 30-day money-back guarantee.

How Fast Is Setup?

"Setup took literally 5 minutes. Our team was making calls in Teams the same day." That's Ashley Moreau from SilverEdge.

The setup process happens in nine steps: verify your Microsoft licensing, select Operator Connect in the Teams Admin Center, choose your carrier, configure your org details, accept terms, set your emergency address, request or port your numbers, and assign them to users.

If you're porting existing numbers, there are no fees on Atlantech's side. The porting process typically takes about two weeks. And if you'd rather not handle any of it yourself, Atlantech assigns a dedicated project manager to every install who walks you through the entire setup process. You can reach out to Atlantech's team to get that started.

Is Operator Connect Right for Your Business?

By now, you have a good sense of what Operator Connect does and doesn't do. Here's a quick way to gut-check whether it's the right fit.

Operator Connect is the right call if you already use Microsoft Teams and have somewhere between 10 and 500 users. You want calling, meetings, and chat in one app without the complexity of managing your own hardware. You don't need custom call routing or SIP trunking, you don't have GCC High requirements, and you like the idea of simple, predictable per-user pricing.

Direct Routing is a better option if your organization needs GCC High compliance for things like CMMC, ITAR, or DFARS. It's also the stronger option if you need SBC failover for business continuity, custom dial plans, or advanced call routing, or if you're running a large contact center.

Microsoft Calling Plans works if you have fewer than 300 employees, want Microsoft to handle everything end-to-end, and have very basic calling needs.

If you're reading that last one and thinking "that sounds fine," it's worth knowing that you'll be locked into Microsoft's rates and support timelines with less flexibility to grow into. Operator Connect gives you that same simplicity with more room to move.

You Don't Have to Pick One Carrier for Each

One thing worth knowing is that Atlantech offers both Operator Connect and Direct Routing. That means the recommendation you get is based on what actually fits your setup, not on which product the carrier happens to sell.

It also means that if you start with Operator Connect and later realize you need something it doesn't support, like contact center integrations, advanced call routing, or virtual reception, you can migrate to Direct Routing without switching carriers.
