Why Does a VoIP Call Drop When a User Switches Headsets?

Switching audio devices during a call can cause the softphone to lose its media path, select an unsupported profile, or reinitialize Bluetooth. Other call controls may continue to work.

What to check

Test supported headsets and connection types, softphone device selection, Bluetooth profiles, firmware, audio permissions, and whether the issue occurs on Wi-Fi or VPN. Compare calls without device switching.

Recommended next step

Use supported device combinations and update client or firmware as recommended. Provide a clear fallback device and validate mute, hold, and transfer after audio changes.
