Microsoft has announced a new feature for Microsoft Teams that will enable IT administrators to conduct silent test calls for proactive network monitoring, set to roll out in September 2025.
This innovative capability represents a significant advancement in enterprise communication infrastructure management, allowing organizations to identify and resolve potential network issues before they impact users.
The feature, identified as Message Center ID MC1089323, will allow IT administrators to run 60-second synthetic call simulations on specific subnets without any user disruption.
These silent tests are designed to run automatically in the background on Windows and Mac desktop clients, providing valuable insights into network performance and call quality metrics.
Key Features and Requirements
The silent test call functionality requires Teams Premium licenses and will only operate on idle devices to ensure zero impact on user productivity.
When devices are actively being used for Teams calls, the testing system will automatically defer until the device becomes available.
Users will experience no notifications, sounds, or visible changes during these background tests, maintaining seamless workflow continuity.
The feature specifically targets network readiness checks by focusing on particular subnets within an organization’s infrastructure.
This targeted approach allows IT teams to systematically evaluate different network segments and identify potential bottlenecks or performance issues that could affect call quality.
Rollout Timeline and Implementation
Microsoft has updated the deployment timeline, with Targeted Release beginning in early September 2025 and completing by mid-September.
General Availability for worldwide deployment will commence in mid-September and finish by late September 2025. The rollout will occur automatically with no administrative action required before deployment.
Organizations should review their current network configurations to assess the potential impact of this new monitoring capability.
Microsoft recommends that IT administrators notify users about the upcoming change and update relevant documentation to reflect the new monitoring procedures.
Benefits for Enterprise Organizations
This proactive monitoring approach enables IT teams to detect and address network issues before they affect end-users, potentially reducing support tickets and improving overall communication experience quality.
By integrating silent test calls into regular operational routines, organizations can maintain higher standards of network performance and user satisfaction.
The feature aligns with Microsoft’s broader strategy of providing enterprise-grade tools for maintaining optimal Teams performance across diverse network environments.
As remote and hybrid work models continue to evolve, such proactive monitoring capabilities become increasingly critical for maintaining a reliable communication infrastructure.
Microsoft has indicated that updated documentation will be provided before the official rollout, ensuring administrators have comprehensive guidance for implementing and managing this new monitoring capability effectively.
