About MS-721 Exam
Why MS-721 is Critical for IT and Unified Communications Professionals
The way businesses operate has changed. Traditional on-premise telephony and siloed communication tools no longer meet the demands of modern collaboration. Organizations need integrated, cloud-based solutions that offer seamless voice, video, and messaging across devices and locations. Microsoft Teams has become a leading choice for enterprises, which means businesses need certified experts to deploy, manage, and troubleshoot Teams communication systems.
The Microsoft MS-721 certification is built for IT professionals specializing in collaboration technologies, voice solutions, and unified communications (UC). It validates skills in Microsoft Teams enterprise calling, Direct Routing, Operator Connect, and conferencing features. If you work in IT administration, network engineering, voice engineering, or collaboration architecture, this cert proves your ability to set up and manage Microsoft Teams as an enterprise communication platform.
Companies rely on Teams for internal and external communication, and they need professionals who understand PSTN connectivity, call routing, security policies, and performance optimization. If you are looking to advance in cloud-based collaboration and voice engineering, MS-721 is a top-tier certification to add to your resume.
Who Should Get MS-721 Certified?
This certification is not just for traditional IT admins it’s designed for specialists who manage Teams communication services and engineers responsible for enterprise voice configurations. If you’re involved in deploying, managing, or troubleshooting Teams calling and conferencing solutions, this certification is highly relevant.
IT Administrators Transitioning to Unified Communications
Many Microsoft 365 administrators already manage Teams, Exchange, and SharePoint but lack expertise in Teams Voice, Direct Routing, and SIP trunking. This cert helps them expand their skill set to include enterprise-grade calling solutions.
