| Allows a user to have a conversation with someone physically
at their workplace without the calling/called party on the telephone overhearing the
conversation. This feature is useful if the
keyset is in a high-noise environment as the user can mute their transmitter cutting out
"noisy" sidetone so they may better-hear the other party. The keyset is un-muted
only when they want to talk.
Mute should also be used if a group-listen call is to be converted to a standard
hands-free call before the handset is placed the cradle to prevent an acoustic feedback
squeal. |
