How MSPs Can Make Microsoft Teams Voice Profitable in 2025

Microsoft Teams Voice isn’t just a feature. It’s the next MSP profit engine.

In 2025, MSPs are operating in a different reality.

Client expectations are higher, compliance demands are more complex, and AI adoption is accelerating at an astronomical pace.

Microsoft Teams Voice sits at the center of this transformation. But while Canalys forecasts a 13% revenue increase for MSPs this year, voice remains one of the hardest offerings to scale.

According to Datto’s 2025 State of the MSP Industry Report, 67% of MSPs expect revenue to rise over the next three years. Yet the majority still struggle with post-migration provisioning, governance complexity, and inconsistent voice support.

The problem isn’t demand, it’s delivery.

Most providers still treat Teams Phone as a checkbox. Meanwhile, industry leaders are building structured, scalable offerings around Teams Phone, provisioning automation, and AI readiness.

The reality is, whether you officially own the telephony piece or not, you’re still on the hook for it. If something goes wrong with voice, your customer isn’t calling their telco. They’re calling you. Voice touches everything from security posture to user experience, and more often than not, you’re already supporting it without seeing any of the upside.

That’s why doing nothing is no longer an option.

For MSPs ready to take ownership, trusted Teams Voice partners offer a way forward. With one trusted partner, you can gain control over customer experience, boost profitability, and strengthen security. It’s not just about managing voice. It’s about making voice work for you.

Why Voice Profitability Breaks Down for Most MSPs 

The issue isn’t deployment. It’s what happens after. 

Most MSPs help clients migrate to Microsoft Teams Phone and stop there as they are not set up to support post-migration demands in a scalable, automated, and low-effort way. 

As a result, clients are left: 

• Managing Teams Phone manually with PowerShell.
• Opening tickets for basic provisioning tasks. 
• Scrambling to enforce policies across sites, departments, and service numbers. 
• Calling their MSP only when something breaks, not when value is needed. 

And MSPs are left: 

• Reacting to noise instead of delivering value. 
• Missing the opportunity to upsell voice as a fully managed service. 
• Spending time navigating faxing systems, device configurations, telco provisioning, and legacy infrastructure—areas that fall far outside modern UCaaS expectations. 

Voice is still treated as a one-time project when it should be an ongoing service. The growing need to be experts in multiple disconnected technologies only adds to the cost, complexity, and margin pressure for MSPs. 

That’s why so many Teams Phone deployments lose momentum post-migration and why profitability lags. 

Turn Teams Voice Complexity into a Service You Can Monetize

Voice workloads are nuanced involving governance, number management, user lifecycle changes, and hybrid scenarios like Direct Routing or existing SIP Trunks.  

That complexity is exactly where most MSP’s lose profitability. But it’s also where the opportunity lies. 

Rather than treating Teams Voice as a bundled add-on, high-performing MSP’s are now productizing voice complexity into structured service offerings. 

Here’s how: 

1. Package Provisioning as a Managed Service 

Voice complexity is exactly where margin lives. 

Moves, adds, changes, offboarding, number assignments, role-based access, these are the workflows that slow down internal IT and frustrate end users when mismanaged. 

Smart MSPs are now packaging this complexity into structured services. With ZIRO’s platform, MSPs can deliver: 

• Provisioning automation for Teams Phone and service numbers 
• Approval workflows and delegated access 
• Self-service interfaces with built-in controls 

This model reduces ticket volume, improves time to resolution, and gives MSPs a way to charge for what’s traditionally been a cost center. 

And more importantly, it’s scalable. According to Datto, 44% of high-earning MSP’s are already leveraging automation to reduce costs and increase margins. 

2. Make Governance the Centerpiece of AI Readiness 

Copilot, by default, surfaces anything a user has access to, including outdated, misclassified, or overshared voice content.  

That means without proper governance, AI becomes an amplifier of noise instead of a driver of clarity. 

Deloitte predicts that 25% of companies that use Gen AI will launch agentic AI pilots or proofs of concept in 2025. That number will double by 2027.  

But as Gartner notes, 30% of these projects are expected to fail due to poor data quality and governance. That’s where MSPs have a clear opportunity to lead. 

By including governance in their service model, MSP’s help clients: 

• Enforce policies across hybrid environments (e.g., Direct Routing, SIP Trunks) 
• Enforce naming and retention policies 
• Monitor for permission drift or configuration sprawl  
• Align voice data with security frameworks like HIPAA, GDPR, and ISO 27001 
• Provide tenant-wide visibility into permission drift and risk exposure 
• Prepare the voice stack for Copilot readiness and future AI workflows 

This gives clients peace of mind and gives MSPs a reason to stay in the room as AI strategy unfolds. 

3. Maximize Client Retention by Making Voice a Recurring Service 

Clients are more likely to stick with MSPs who support ongoing Teams Phone governance, proactive insights, and AI readiness.  

The real margin comes from keeping those clients long after migration and not from landing them.  

This is how that looks in practice: 

• Voice health checks: Monthly or quarterly reporting on usage, quality, and trends 
• SLA-based performance management: Ensuring uptime and rapid issue resolution 
• Ongoing policy alignment: Keeping Teams configurations aligned with org changes 
• Copilot readiness audits: Helping clients prepare voice and meeting data for AI 

Clients don’t want a reactive vendor. They want a proactive partner. And they’re willing to pay for the confidence that their voice stack is aligned, monitored, and future-proof.
