How to Use
PC audio
In "PC Audio" mode, you can directly use the PC mic and speaker (headset) as the meeting audio connection method

meeting, we recommend you use "Call In" as the audio connection method, which has a better audio quality.

window.
You can also click the arrow on the right of Mute/Unmute in the toolbar of the meeting window and select PC Audio.

Meeting Audio pop-up window, so that you don't need to select the audio connection method again when joining a
meeting next time, and PC audio will be used by default.
PSTN Call in
In "Call In" mode, you can use a landline or mobile phone to dial the corresponding number to join a meeting, and the
phone rather than the PC mic and speaker will be used as your meeting audio source, which has a more stable call
audio quality. However, in this connection method, your carrier will charge you for the local or international call
according to applicable billing rules.
