1.12 Conversation Features
Conference, 3-Party
Description
The system supports 3-party conference calls which include outside or inside parties or both.
During a 2-party conversation, the extension user can add a third party to their conversation,
thereby establishing a conference.
Conditions
• Conference call arrangement
A conference call can be one of the following three arrangements:
1-inside and 2-outside; 2-inside and 1-outside; and 3-inside.
• Conference trunk
Up to eight conference calls are available at a time by default. If the optional TSW
Conference Expansion card is installed, up to 64 conference calls are available
simultaneously.
• Executive Busy Override, Privacy Release
A 3-party call is also established by Executive Busy Override or Privacy Release.
• Confirmation tone
When a 2-party call is changed to a 3-party conference call and vice versa, a confirmation
tone is sent to all three parties. Eliminating the tone is programmable <Section 2.8 System
Option, "8 Confirmation tone for Override, Barge-in, Conference and Privacy Release" in
the Programming Guide>.
• CONF (Conference) button
If a CONF button is not provided on a PT, it can be assigned to a flexible (CO, DSS, PF)
button by Station, User or System Programming.
• Call Splitting
During a 3-party conference call, the conference originator can talk to either one of other
two parties alternately by pressing the TRANSFER button (for PT user) or flashing the
switchhook (for SLT user). In this case, the PT user is connected with the latter party first
and the SLT user is connected with the previous party first.
• Released Link Operation
If "Released Link Operation" is enabled at an SLT <Section 2.4 Class of Service (COS),
"Released Link Operation" in the Programming Guide>, a conference call cannot be
established.
