Section 700 - Operation
•
2 extension and 2 trunk lines
•
1 extension and 3 trunk lines
When the optional 8-party conference card is installed, the System supports any combination of
conference calls, except all outside lines.
Operation
See Section 750 - Key Phone User Guide for operating instructions.
Hardware Requirements
•
A Conference Card (VB-44120) must be installed in the System in order to conference more than
four parties.
Considerations
•
If all the internal parties hang up, the conference call will be disconnected. If the internal party
remains in the conversation, the conference call remains in progress.
•
When three or four parties are conferenced, a built-in 4-party conference circuit is used. If no
4-party conference circuit is available, a conference cannot be established.
•
When a fifth party is added, the conference is moved to a conference circuit on the 8-party
conference card. If an 8-party conference circuit is not available, a fifth party cannot be added to
a conference.
•
Once an 8-party conference circuit is used, it continues to be used as long as the conference
continues.
•
An 8-party conference card supports up to four 8-party conference circuits. However, the card
must be placed in cabinet slots 1, 5, or 9 to support more than one 8-party conference circuit (and
jumpered accordingly).
•
During a conference call hold, the held conference members cannot use the HOLD key. Pressing
the key has no effect.
•
Conference Hold is an Exclusive Hold (only the conference originator can retrieve the
conference).
•
Conference Hold cannot be transferred.
Do-Not-Disturb
Description
You can make an extension unavailable by activating the Do-Not-Disturb (DND) feature. When DND
is activated, calls to that extension receive busy tone.
You can set or cancel DND from either your extension or from an alternate extension.
