optional Conference Card is installed, additional parties up to a total of 8 can participate in a
conference call.

next party and press the CONF key. No different operation or access code is required to add

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).
