Healthcare runs on coordination. When communication systems lag, clinicians feel it first, and patients feel it most. That’s why one major academic medical center in the U.S., a top-tier institution with more than 80 specialties, made the decision to modernize its unified communications environment.
It was essential to avoid interrupting care, but the scale made it a challenge: 500+ Microsoft Teams endpoints, four legacy systems, and a need to carry forward long-standing workflows while maintaining compliance and reliability.
From the outset, the organization brought in Mitel’s services team to help manage the operational load and protect clinical continuity. The mandate was clear: Upgrade the environment without creating risk for staff or patients, and without placing yet another heavy lift on an already stretched IT department.
Why communication modernization is different in healthcare
Every health system is balancing aggressive digital modernization targets with limited internal capacity. Even well-resourced teams juggle system maintenance, clinical integrations, security pressures, and the operational demands of a 24/7 care environment.
In this case, the stakes were clear:
- Life-critical coordination depended on predictable communication flows.
- Legacy workflows needed to stay intact while migrating to Microsoft Teams.
- Security and compliance guardrails had to remain firm during every phase.
- Rapid resolution of incidents was essential to clinical uptime.
The organization sought a sustainable operational model rather than simply the most advanced technology. That mindset is becoming more common among healthcare leaders: recognizing that modernization is as much about managed execution as it is about technical architecture.
From fragmented infrastructure to a unified, monitored environment
Before the project began, the medical center faced issues familiar to many health systems:
- Fragmented communication infrastructure across clinical and administrative areas
- Multiple legacy systems that limited interoperability
- Rigid telephony paths and bottlenecks linked to older security and SBC configurations
- Limited visibility into real-time performance
- Pressure on internal teams to manage issues across platforms, vendors, and endpoints
The answer paired Microsoft Teams with Mitel’s Managed Services Agreement (MSA), a model designed to integrate hybrid environments while relieving internal IT of the burden of day-to-day management. The combined architecture used Microsoft Teams, Mitel OpenScape Voice, and Talkdesk, supported by dual redundant session border controllers and a zero trust VPN layer for compliance.
A dedicated Mitel service team monitored systems around the clock, handled tailored change management, and cared for the communication environment as a continuous service, as opposed to a project with a singular end date.
This approach allowed the medical center to maintain operational continuity throughout the migration. Clinical and administrative workflows remained intact, and the IT team gained a clearer view of the entire communication ecosystem without having to be hands-on during every moment.
Demonstrated results: faster resolution, smoother operations, more capacity for strategic work
The measured outcomes speak directly to the pressures healthcare CIOs and directors face today:
- Incident resolution time improved by 45%, allowing issues to be addressed before they affected clinical operations.
- Uptime now exceeds industry benchmarks, reducing operational noise and service interruptions.
- 500+ Teams endpoints were integrated with established PBX workflows, preserving the familiar user experience clinicians were relying on.
- Internal IT gained back time previously spent tracking, troubleshooting, and coordinating across vendors.
- Infrastructure capacity scaled quickly enough to support new facilities without delay.
These improvements came less from technology decisions than from prioritizing the reduction of operational drag. By shifting ongoing management to a specialized service team, the healthcare organization created predictability across its communication environment. This predictability is a practical advantage when every minute of downtime has clinical implications.
The broader takeaway for healthcare technology leaders
The lesson from this transformation is not that communication environments must become simpler. Most won’t. Hybrid ecosystems, clinical integrations, layered security models, remote diagnostics, and distributed facilities will continue to introduce necessary complexity.
The key learning is that complexity doesn’t have to be managed alone.
Healthcare IT teams are responsible for an extensive landscape: EMR integrations, cybersecurity posture, regulatory compliance, device ecosystems, network resiliency, user support, and ongoing modernization. Adding full-time, deep monitoring and change operations for voice and collaboration can stretch even strong teams.
What this academic medical center recognized, and what many leaders are now acknowledging, is that managed services are about sharing responsibility 1in a structured way that ensures:
- Continuous operational awareness
- Faster incident detection and resolution
- Capacity for internal teams to stay focused on long-horizon initiatives
- Confidence that communication systems won’t become a single point of failure
During early planning, it became clear that the IT team needed space to focus on long-range priorities rather than getting pulled sideways by day-to-day escalations. That perspective shaped the entire engagement. Once the operational load shifted, the team could look ahead to the work that mattered most instead of managing constant context switching.
Modernization that meets healthcare where it operates
Every health system has its own architectural mix and operational rhythms, but one theme is consistent: leaders need partners who understand the stakes and can operate with the same level of urgency their clinicians do.
At Mitel, we’ve designed our managed services model to support that reality. For organizations navigating Microsoft Teams integrations, hybrid UC modernization, or multi-system consolidation, the goal stretches far beyond cleaner technical design, toward a sustainable way to run it.
