Voice Enable Microsoft Teams
Your team already lives in Teams. The question is how to connect it to the phone network without buying more Microsoft licenses than you need. We help you compare every path, then implement the one that fits.
What It Means to Voice Enable Teams
Out of the box, Microsoft Teams handles chat, meetings, and file sharing. What it cannot do is call a regular phone number. Voice enabling Teams means connecting it to the public phone network so your people can make and receive everyday phone calls from the same app they already use all day.
Most organizations start by pricing Microsoft's own phone licenses. That is a reasonable first step, but it is only one of four paths, and it is rarely the most capable or the most cost-effective one. The other three paths run through carriers and UCaaS providers, and they are where most organizations land once they see the full picture.
The License Math Gets Complicated Fast
- 01 "We priced out Teams Phone with Calling Plans and the per-user cost nearly doubled our Microsoft bill."
- 02 "Our paging system, elevator phones, and fax lines have nowhere to go on Microsoft Calling Plans."
- 03 "Nobody could tell us exactly how 911 location would work across our buildings."
- 04 "Minutes, add-ons, license tiers. Every quote looked different and none of them matched."
- 05 "We need call queues and reporting that basic Teams Phone licensing does not really cover."
Teams Stays. The Phone Bill Changes.
You do not have to choose between Teams and a full-featured phone system. Leading UCaaS providers connect directly into Teams, so your people keep the app they know while you get better calling features, stronger support, and often a lower monthly cost than Microsoft's own Calling Plans.
See how it worksFour Ways to Add Calling to Microsoft Teams
Every voice-enabled Teams deployment uses one of these four connection paths. Many organizations mix them, using one path for headquarters and another for sites with special needs.
Microsoft Calling Plans
Microsoft acts as your phone carrier. It is the simplest way to start, managed entirely in the Teams admin center. The tradeoffs: higher ongoing per-user costs, limited country coverage, no native analog device support, and calling features that stay basic.
Best for: small, single-site teams with simple calling needs.
Microsoft as CarrierOperator Connect
A certified carrier or UCaaS provider delivers calling directly into Teams through a pre-built Microsoft connection. It deploys in days with no extra hardware, keeps management inside the Teams admin center, and typically lowers ongoing calling costs per user.
Best for: organizations that want better rates and support without added complexity.
UCaaS Provider PathDirect Routing
The most flexible path. A provider connects Teams to the phone network through a session border controller, so you can keep existing numbers and contracts, support analog devices, and build custom call flows across every site.
Best for: multi-site organizations with analog devices or complex call flows.
UCaaS Provider PathEmbedded Calling Apps
A UCaaS provider's calling app runs inside the Teams client with its own dialer. Your people call, message, and check voicemail without leaving Teams, while calling runs on the provider's platform and is managed in the provider's console instead of the Microsoft admin center. Because the native Teams dialer is never used, no Teams Phone licenses are required at all.
Best for: organizations that want Teams as the front door without paying for Microsoft phone licensing. This is the path most of our clients choose.
UCaaS Provider PathOperator Connect, Direct Routing, and embedded calling apps are all delivered by UCaaS providers. The difference is where the calling lives: the first two use the native Teams dialer and are managed largely inside Microsoft, while an embedded app keeps the dialer and the administration on the provider's side. For a deeper look at where Teams Phone falls short, read why UCaaS integration matters.
What Microsoft Phone Licenses Really Cost
Teams Phone pricing rose in 2025, the first increase since the product launched. Before committing, it is worth lining up the real monthly math against what a UCaaS provider would charge for the same users with more calling features included.
Pricing reflects published Microsoft list prices as of mid-2026 and can vary by agreement type. All of these amounts sit on top of your existing Microsoft 365 subscription. An embedded calling app skips this table entirely, because calling runs in the provider's app inside Teams and no Teams Phone licenses are required. For the full breakdown, read The Real Cost of Teams Phone.
Why Voice Enable Teams Through a UCaaS Provider
Pairing Teams with a UCaaS provider gives you the experience your people want and the phone system your organization actually needs.
Keep the Teams Experience
Your people keep making calls from the Teams app they already know. No new software to learn, no second dialer to explain, no change management headache.
Lower, Predictable Calling Costs
Provider calling rates typically come in well below Microsoft Calling Plans for the same usage, with clearer bundles and fewer surprise add-ons at renewal.
Full-Featured Calling
Auto attendants, advanced call routing, queues, analytics, SMS and fax options, and a clear path to contact center capability when you need it.
Analog Devices Keep Working
Paging systems, door intercoms, elevator phones, and fax lines stay in service through gateways and Direct Routing. Microsoft Calling Plans have no native support for any of them.
E911 Done Right
Dynamic location routing and compliance with Kari's Law and RAY BAUM'S Act, designed around your actual buildings and floor plans rather than left as an open question.
Real Support When It Matters
A named provider with voice-specific SLAs, plus Maverick alongside you before, during, and long after go-live. No support ticket black holes.
A City That Made Teams Its Phone System
The City of Oceanside replaced aging on-premises voice systems with a cloud platform whose calling app runs inside Teams, at no added license cost. That is Path 04 in practice. More than a thousand employees kept the app they knew, no Teams Phone licenses were needed, and the hardware burden disappeared.
"A few vendors said, 'We'll show you how to do two phones and then turn you loose.' Maverick said, 'We'll help you all the way through.'"
David Riha IT Director, City of Oceanside
UCaaS Providers That Integrate with Teams
Leading UCaaS providers offer certified Microsoft Teams integrations through Operator Connect, Direct Routing, or embedded calling apps. Each differs in coverage, calling features, contact center options, and pricing. As a supplier-neutral advisor, we help you compare them against your requirements and negotiate from an informed position, without leaning on any single vendor.
These are examples of providers with Teams integrations, not a ranking or endorsement. The right fit depends on your sites, calling patterns, compliance needs, and budget.
E911 Compliance, Handled
Emergency calling is where Teams voice projects get real. Federal law requires direct 911 dialing and accurate dispatchable location for every caller, on every floor, in every building. We make sure your Teams calling design meets both requirements before anyone goes live.
Kari's Law
Requires direct 911 dialing with no prefix, plus automatic notification to on-site personnel when an emergency call is placed. Your Teams calling setup must handle both.
RAY BAUM'S Act
Requires a dispatchable location, such as building, floor, and room, to be delivered with 911 calls so responders find the caller fast. This takes planning across networks and sites.

Microsoft Teams Voice FAQs
Can Microsoft Teams be used as a full phone system?
Yes. Out of the box, Teams handles chat and meetings but cannot call regular phone numbers. To use Teams as a phone system, you connect it to the public phone network through one of four paths: Microsoft Calling Plans, Operator Connect, Direct Routing, or a provider's embedded calling app that runs inside Teams. The last three are delivered by carriers and UCaaS providers, and they are how most organizations get full-featured calling inside Teams.
Do I need a Teams Phone license to use a UCaaS provider with Teams?
It depends on the integration model. Operator Connect and Direct Routing use the native Teams dialer, so each user needs Teams Phone capability, either the Teams Phone Standard add-on or a plan that includes it. Embedded app integrations run the provider's calling app inside the Teams client, which can remove the need for Teams Phone licenses entirely. We help you compare the license math for both models.
What is an embedded dialer, and is it different from an embedded app?
They are the same thing. Several leading UCaaS providers offer an app that installs inside the Teams client and brings its own dialer, so your people call, message, and check voicemail without leaving Teams while the calling itself runs on the provider's platform. Because the native Teams dialer is not used, no Teams Phone licenses are required. You may hear it called an embedded dialer, an embedded app, or an embedded calling app.
What is the difference between Operator Connect and Direct Routing?
Both connect Teams to the phone network through a provider you choose. Operator Connect is a certified, pre-built connection managed right in the Teams admin center, and it deploys quickly with no extra hardware. Direct Routing uses a session border controller and offers maximum flexibility, including support for analog devices, existing carrier contracts, and complex call flows across multiple sites.
How much does it cost to add calling to Microsoft Teams?
Using Microsoft licenses alone, Teams Phone plus a Calling Plan typically runs $17 to $34 per user per month on top of your Microsoft 365 subscription. Voice enabling Teams through a UCaaS provider often lowers the ongoing calling cost per user and includes more calling features. Exact pricing depends on the provider and your calling patterns, which is exactly what a neutral comparison sorts out.
Can we keep our existing phone numbers?
Yes. Phone numbers can be ported to the new provider or, with Direct Routing, you can keep existing carrier contracts in place. Number porting is a standard part of a coordinated implementation plan, and we manage it as part of the project.
What happens to analog devices like paging, elevator phones, and fax lines?
Microsoft Calling Plans have no native analog support, which is one of the most common reasons organizations look beyond Microsoft licenses. Basic analog calling is possible through Teams SIP Gateway with certified adapters, but it adds licensing per endpoint and stays limited. UCaaS providers using Direct Routing, analog gateways, or companion services keep paging systems, door intercoms, and elevator phones working properly alongside Teams. Fax is not supported in Teams at all and needs a separate service.
