When Microsoft Stumbles, ComTec Keeps You Moving
On March 3rd, a small number of businesses using Microsoft Teams for their Auto-Attendant (AA) functionality experienced an issue where incoming calls were met with busy signals. While the problem originated from Microsoft, ComTec Systems quickly identified the issue and took immediate action to support affected clients.
Microsoft’s outage left businesses with busy signals—ComTec stepped in fast to keep clients connected.

The Bigger Picture: Why Microsoft Isn’t Built for Business Phones
This incident highlights a key reality: while Microsoft Teams is a powerful collaboration tool, it wasn’t designed for business-critical phone systems. When issues arise, businesses relying solely on Microsoft are often left waiting for a fix—because telecom simply isn’t their expertise.
At ComTec, we do things differently. Our solutions ensure your voice communications remain reliable, independent of Microsoft’s stability. When Teams or other collaboration platforms experience disruptions, our clients stay operational because we provide dedicated, business-grade phone solutions that don’t rely on a one-size-fits-all approach.
Why ComTec Clients Stay Ahead
While Microsoft worked to resolve the issue, ComTec had already stepped in to ensure affected clients stayed connected. Our quick response, expertise, and ability to provide immediate solutions meant our customers experienced little to no disruption. This is what sets us apart—we don’t wait for problems to be fixed; we take action to keep your business moving.
At ComTec, we’re more than a service provider—we’re a true partner in business continuity. When the unexpected happens, we make sure you don’t just recover—you stay ahead.
