2. Introduction
Why voice matters now
In 2025, businesses are not just adopting Teams for messaging and meetings; they are replacing legacy PBX systems, consolidating communication tools, and simplifying workflows. The expectation is clear: seamless internal and external voice communication, all within a unified platform. However, challenges remain. Many enterprises face complexities around carrier selection, number porting, compliance, and ensuring service quality. IT teams are tasked with managing Teams voice at scale, often without the in-house expertise traditionally held by telecom specialists.
All you need to know about migrating to Microsoft Teams Phone. Just a few years ago, voice services were often managed by telecommunications teams, completely separate from the IT department. Today, the landscape has changed. The rise of hybrid work has redefined how we collaborate, and Microsoft Teams has become the global go-to platform for communication. As part of the Microsoft 365 suite, Teams is deeply integrated with productivity apps, making it an essential part of the digital workplace. For many enterprises, adding voice to Teams is the next logical step in their transformation journey — streamlining operations and reducing costs.
