1) If the earbuds were playing sound from the meeting, the issue might be due to the settings of the web conferencing program. When selecting the Buds channel in the web conferencing program, it periodically forces the sound route to switch to the earbuds. As a result, when you are connected to a meeting on Device A and receive a call on Device B, the earbuds continue to output sound from the meeting and cannot switch to the mobile phone call.
Solution: Change the audio channel in the web conferencing app to the system default.
2) If there was no sound playing from the web conferencing application on the computer through the earbuds, reset the earbuds to factory settings and then reconnect them, or try restarting the mobile device and attempting again.
