You can mute your speech connection to a call. Whilst a call is muted, you can hear the caller but they cannot hear you.
•Phone Mute Controls
The one-X Portal does not reflect the status and use of the mute button on your phone. You should only use your either you phone or one-X Portal to mute and unmute calls.
Retrieving a parked call cancels any muting that may have previously been applied to that call before it was parked.
If you mute a call and then put it on hold, that muting is canceled when you unhold the call. However, if you mute a call and the other party holds the call, the muting is not canceled when the call is taken off hold.
If you are the conference host, you may be able to mute other parties in the conference. See Muting Conference Parties.
