Description
When a proprietary telephone user is in a conference with two
outside parties, the user can leave the conference to allow the other
two parties to continue conversation. This is called an Unattended
Conference. The user may return to the conference, if desired.
Conditions
• An Unattended Conference can be established when the extension is
allowed to transfer a call to an outside line.
• The duration of an unattended conference is restricted by a system
timer. Hold Recall results to the extension user who left the conference
50 seconds before the time-out. An alarm tone is generated to both
outside parties 15 seconds before the time-out. The call is disconnected
at the time-out unless the extension returns to the call.
