Abstract
A telephony exchanges allows terminating equipment to indicate whether a telephone call is public, where the telephone conversation may be heard by more than one person at a remote end of a call, or private, where a person at the remote end of a call employs, for example, a handset or a headset. A calling party can restrict a called party from holding a call in a public mode if so desired either before or during the call and is provided through their terminating equipment with an up-to-date graphical display, textual display or physical indication of the status of whether the called-party is operating in a public mode. The called party may also be provided through their terminating equipment with an up-to-date graphical display, textual display or physical indication that they should not put a call on speaker, if the calling party has so decided. If the calling party decides during a call to restrict a call to private mode, the calling party's terminating equipment indicates this and also, if necessary, a prompt is played informing the called party to change to private mode.
