A user, who has a digital telephone with a display, or an attendant with an attendant console, can use the Selective Conference Party Display, Drop, and Mute capability to identify the participants on a call.

The conference prompts that the system displays are based on the user Class of Restriction (COR). The display prompts are based on the user COR, independent of the select line appearance conferencing and the No Dial Tone Conferencing capability. The display messages vary depending on the activation of the various Conference capabilities. The user COR controls the display of any additional information.

A user presses the administered conf-dsp feature button to scroll through the telephone numbers and names of the participants on the call. The telephone numbers of the participants are always available, although the names of the participants are sometimes unavailable. When the system displays the telephone number of a participant, the user can either press the administered fe-mute feature button to place the participant on mute, or the user can press the drop button to drop the participant from the call.

The ability to place a call participant on mute is useful when that participant has a noisy trunk line because of a cell phone, music-on-hold, or background noise. The Selective Conference Party Mute capability applies only to trunk lines, and a user can mute only one trunk line on a conference call.
