Muting the Speakerphone
If you have a Mute key, you can press it to turn off the microphone, so
that you can carry on a conversation in your room that the other party
on your line cannot hear.
Mute is also helpful when someone puts you on hold, since it lets you
hear your party reconnect even if there is a high noise level in your
room.
To mute the
speakerphone ➩ During your conversation, press the Mute
key.

to remind you that Mute is active.

will not be picked up by the speakerphone.
