1.1.34 Conference, Unattended
Description
The proprietary telephone (PT) user who originated a conference with 2 outside parties can leave the
conference and allow the other parties to continue the conversation. The user may return to the conference
at any time, if he or she desires.
Conditions
• Conference Button
On a PT that does not have a CONF (Conference) button, a flexible CO button can be customized as
a Conference button.
• Consultation Hold
When an extension user tries to establish a conference call, the current call is automatically placed on
consultation hold until the conference is established (
1.1.36 Consultation Hold).
• Unattended Conference Recall
The duration of unattended conferences is restricted by a system timer ( [205] CO-to-CO Line Call
Duration).
A ring tone or an alarm tone is heard at the conference originator's extension 50 seconds before the
timer expires.
A warning tone starts to be heard by parties in the unattended conference 15 seconds before the timer
expires.
If the originator returns to the conference before the unattended conference call is disconnected, the
timer will be canceled. If not, the ring tone or alarm tone and the warning tone will continue to be heard
until the unattended conference call is disconnected ( 1.1.91 Outside-to-Outside (CO-to-CO) Line
Call Duration).
• An unattended conference cannot be established unless the extension is allowed to transfer a call to
an outside party through system programming ( [606] Call Transfer to CO Line).
