1.14.1.2 Conference
Description
An extension user can establish a conference call by adding additional parties to an already existing two-party
conversation. This PBX supports three-party through eight-party conference calls. Conferences with more than
four parties are only possible when a PT or PS user originates the conference.
Unattended Conference:
The conference originator can leave the conference and allow other parties to continue. Establishing an
Unattended Conference allows the originator to return to the conference. Unattended Conferences can only
be established by PT and PS users.
Conditions
•
When an extension is establishing a conference call the original party is put on hold.
•
CONF (Conference) Button
For a PT/PS which does not have the CONF button, a flexible button can be customised as the Conference
button.
•
Unattended Conference Call Duration
The length of time that a conference call can remain unattended is restricted by the following timers:
–
Callback Start Timer
–
Warning Tone Start Timer
–
Disconnect Timer
These timers behave and operate according to the following chain of events:
1.
When the unattended conference is established, the Callback Start Timer will begin.
2.
When the Callback Start timer expires, the Unattended Conference originator’s extension will start to
receive a callback ringing from the PBX and the Warning Tone Start Timer begins.
3.
When the Warning Tone Start Timer expires, the remaining parties of the conference will start to hear
a warning tone, the callback ringing will continue to be heard at the Unattended Conference
originator’s extension, and the Disconnect Timer begins.
4.
When the disconnect Timer expires, the conference is disconnected.
If the Unattended Conference originator returns to the conference before the line is disconnected, all timers
are cleared.
•
For a Conference With Six or More Parties
The EECHO or ECHO card is required. Also the echo cancelling function should be enabled through system
programming.
