Hardware Requirements
•
A Conference Card (VB-44120) must be installed in the System in order to conference more than
three 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 parties are conferenced, a built-in 3-party conference circuit is used. If no 3-party
conference circuit is available, a conference cannot be established.
•
When a fourth 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 fourth 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).
