 To mute all other participants or mute a specific participant, you can use the asynchronous APIs `muteAllRemoteParticipants` on the call and `mute` on the remote participant. The `mutedByOthers` event from Call is raised when the local participant has been muted by others.
 
+ *Note: The scenario to mute PSTN (phone number) participants is not supported.*

 ```js
 //mute all participants except yourself
 await call.muteAllRemoteParticipants();
