Knowledge Base & Operational DocumentationWhy Does a VoIP Call Sound Fine Until Someone Starts Screen Sharing?
Screen sharing can consume bandwidth and device resources, revealing congestion that ordinary voice calls do not show. Users may experience robotic audio or dropped calls only when meetings include video or shared content.
What to check
Compare voice quality with and without screen sharing, check Wi-Fi signal, upload capacity, CPU use, meeting platform statistics, VPN path, and competing traffic. Determine whether the issue affects one endpoint or everyone on the network.
Recommended next step
Improve the constrained network or device layer and prioritize real-time traffic only where the network can support it. Test typical meeting loads and avoid promising that QoS can compensate for insufficient capacity.
