You moved to Microsoft Teams. Meetings, chat and calling now live in one place, Copilot is arriving on top of it, and your people already know how to work in it.
Then there’s the contact center.
For most organizations, it’s the one part of the business still running somewhere else. It might be an established on-prem platform that has served you well for years, a stand-alone cloud contact center sitting next to Teams, or a set of telephony pieces that were never designed to work together. It works. Calls get answered. So it keeps getting pushed to next year’s plan.
This article is about what that decision costs. It’s not a vague “digital transformation” cost. It shows up in five specific places: your budget, your agents, your customers, your control, and your ability to use AI. After that, we’ll look at what the alternative looks like when the contact center lives inside Teams, and how to get there without a risky cutover.
Nobody designed this. It just accumulated.
Very few contact centers were designed. They were assembled. Telephony came first, then queues, then CRM, recording and reporting. Most recently, AI went on top. Many contact centers have spent years layering telephony, CCaaS, CRM and now AI on top of each other.
Many leaders realize they built an architecture that works for humans stitching pieces together, not for AI. The part that matters most for CX is this: customers can’t see your architecture, but they feel it on every call.
The agent who doesn’t have the history. The customer who repeats their account number for the third time. The transfer that drops the context. None of these are people problems. They’re the architecture showing up in the conversation.
The real cost: five places it shows up
1. You pay twice for the same job
A contact center platform that sits outside Teams means a second set of licenses, a second support contract, a second set of skills to keep on staff, and a second set of integrations to maintain.
Teams-first organizations increasingly ask the same question: if Teams already carries the rest of our communications, why keep a separate platform for the contact center? Analysts on one industry panel noted a big overlap between organizations that run contact centers and organizations that use Teams. Luware makes the case from the vendor side: for companies already invested in the Microsoft ecosystem, a Teams contact center reduces IT costs and simplifies the architecture.
You don’t need a spreadsheet to see the pattern. Every platform you keep outside Teams is a platform you pay to run, secure, upgrade and staff, on top of the Microsoft 365 you already own.
2. Your agents work harder than they should
Bolt-on tools mean extra screens, pop-up windows and logins. Every switch costs a few seconds and some attention, and it happens in the middle of a live conversation with a customer.
It also makes new people slower to get good. That matters more now, because many companies are bringing contact center work closer to home. Cost used to drive offshoring decisions, but turnover, agent success and regulatory compliance are now shaping the move back onshore. If you’re building or growing an in-house team, the tools they have to learn become part of the business case.
When agents work in an interface they already know, they ramp faster. Luware says that because agents work in the familiar Teams interface on one platform, training time can be cut by 50%. That’s Luware’s own claim, so test it against your own onboarding numbers. The principle holds either way: fewer tools to learn means faster, more confident agents.
3. Your customers feel the seams
Customers don’t care which vendor owns which queue. They care that they got through to the right person, that the person knew who they were, and that the problem was solved without a second call.
Every seam between systems is a place where context gets lost. The customer explains it again. The agent asks again. The call gets longer, and the customer leaves a little less happy than they arrived.
4. You lose control
A contact center bolted on from outside often means calls, recordings and customer data passing through another vendor’s environment. That makes governance, security reviews and compliance harder.
A design built into Teams works differently. Luware describes its approach as keeping data inside your own tenant rather than leaving your perimeter, and as running 100% inside Teams instead of in external pop-up windows. If you operate in a regulated industry, or you plan to, the question of where your calls and data live is not a detail.
5. You can’t get the full value from AI
This is the cost that’s growing fastest. Every contact center leader is under pressure to “do something with AI,” and most are discovering that AI is only as good as the architecture under it.
Microsoft’s Alpana Bajaj warns that bolting AI onto siloed systems leads to conflicting answers, slower resolutions and stalled innovation. There’s also a plumbing issue. AI voice agents are now deployed at scale, and their latency requirements expose weaknesses in older infrastructure that contact center teams were never designed to manage.
Microsoft’s own experience points the same way. Microsoft has reported saving $500 million in its contact centers through AI-driven efficiencies, after consolidating fragmented systems onto a unified platform with better routing and integrated data. The order matters. They unified first, and AI paid off second.
So what does modern CX in Teams actually look like?
Let’s follow one call from start to finish, shall we?
Before anyone picks up.
The caller is recognized and the reason for the call is understood. The call goes to the right person, not just the next free one. Where it makes sense, an AI virtual agent can handle routine steps, like identity checks, while the customer is still waiting.
"Verifying each caller takes about 90 seconds, so for a bank handling 100,000 calls a month, automating just that step could free up around 2,500 hours of agent time. That’s Luware’s own estimate. It’s an illustration of the kind of work AI can take off people, not a promise for your numbers."
During the call.
The agent works inside Teams, with the caller’s context in front of them. An AI assistant works quietly in the background. Luware’s Companion transcribes and summarizes calls so agents can listen instead of scrambling to take notes. The agent’s attention goes to the customer.
After the call.
The summary already exists. Follow-up tasks can start on their own. Luware builds on Microsoft’s own tools, including Azure services and Power Automate, to connect workflows across the business. Nobody reconstructs the call from memory.
Behind the scenes.
Supervisors and IT see what’s happening in one place, using the Microsoft environment they already manage.
Connected to Teams is not the same as built into Teams
This distinction is worth understanding before you evaluate anything. Microsoft supports three integration models for contact center solutions: Connect (certified SBCs and Direct Routing), Extend (cloud communication APIs), and Unify (native, built on Azure Communication Services).
A contact center can be connected to Teams in a way that still leaves it as a separate application with its own interface. Or it can be built into Teams so the agent never leaves it. Luware chose the second route, rebuilding its platform natively within Teams using the Extend model, so agents can take calls from either the contact center console or the Teams client. For agents and IT, the difference shows up every day.
“We can’t rip and replace”
Of course you can’t.
A contact center is mission-critical, and the platform you run today has carried your customers for years. The goal isn’t to throw it away overnight. It’s to make sure your next step is one you choose, on your timeline, without putting customers at risk.
The answer isn’t a big bang. It’s a staged path where the old and new run side by side. This is the idea behind Aura’s “Integrate to Migrate” approach: connect Microsoft Teams to your existing PBX, contact centers and analog systems, so the migration can happen in steps while the business keeps running. In practice, that usually looks like this:
- Map what you run today. Queues, routing logic, integrations, recording, reporting. Most of the risk in a migration lives in the things nobody has written down.
- Bring voice into Teams first. Aura Connect delivers global voice in Teams through Operator Connect, Direct Routing and SBCaaS, with PSTN coverage in 89+ countries and on-site “Smart Hands” support in 170+.
- Move queues in waves. Start with a team or use case that’s low-risk and high-visibility. Prove it. Then expand.
- Retire the legacy platform when the last queue is live, not before.
This is where experience counts. Aura brings over 30 years of experience in global voice and collaboration, and deploys and integrates Teams Voice and CX platforms around the world. Aura’s long-standing approach is to integrate systems while you migrate, at a pace that suits you, with one invoice and a single point of contact. Whether you’re running an established on-prem platform or a stand-alone cloud contact center, the principle is the same: don’t make the business pay for the migration in downtime.
How to put a number on the cost for your business
If the answers make you uncomfortable, that’s useful. It means the cost is real, and it’s growing. Join our upcoming webinar to see how Aura and Luware Nimbus can help.
The contact center doesn’t have to be the last thing you modernize
You already made the big decision to build your communications on Microsoft. The contact center is the piece that’s been left outside it. Closing that gap is mostly about sequencing, and it doesn’t have to be a leap.
