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 customized 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 canceling function should be enabled through system programming.
