Why Do VoIP Calls Sound Fine Until a Screen Share Starts?

Screen sharing can increase traffic and CPU use, exposing capacity or prioritization problems that are not visible during voice-only calls.

Checks to make

Compare call metrics before and during sharing, check Wi-Fi airtime and uplink use, inspect endpoint CPU, and test wired and wireless paths. Confirm QoS markings are preserved across network equipment rather than assuming they are honored.
