Considerations
•
A single-line telephone can have up to 6 parties on a conference call, if each conferee adds
another conferee. For example, one user can add a party, who then adds a third party, and so on.
•
If you do not allow trunk-to-trunk connections and a telephone releases from a conference call
(where all of the other parties were connected to the conference via trunks), then all parties are
disconnected.
•
If an analog single-line set has Call Wait active and creates a conference call, Call Wait is
rendered inactive as long as the single-line set is on the call. For example, caller A on an analog
set talks to caller B, flashes to talk to caller C, and flashes to conference B and C. Then, if caller D
calls caller A, Call Wait is denied.
•
Users of Digital Communications Protocol (DCP), Hybrid, and wireless phones can conference a
call on hold. If there is only one call on hold, no active call appearances, and an available call
appearance for the conference, a user can initiate the conference process without taking the call
out of hold. When the Conference button is pressed, Avaya Communication Manager assumes the
conference is for the call on hold, and the conference feature works as usual.
If there is more than one call on hold, the user must make a call active in order to include it in a
conference. If the user presses the Conference button with two or more calls on hold, Avaya
Communication Manager will ignore the conference attempt since it will not know which call the
user wants to conference. If there are calls on hold and an active call, pressing the Conference
button will start the conference process for the active call.
•
You can allow users to abort a conference operation that is in progress by hanging up the phone.

Loss Plan on Conference Calls – The end-to-end total loss for multi-party conference calls that is
administered on the
applied to, for example, a 3-party conference call is calculated by adding the fixed pairwise loss
for each pair of ports to the value for 2-party loss shown on the
this total is less than the end-to-end total loss value configured for a 3-party conference, calculate
the difference, and divide the difference by 2. Add 1 to this figure, and the result is the amount of
loss applied to the call.
Conference/Transfer Toggle/Swap
Conference/Transfer Toggle/Swap allows users to toggle between two parties in the middle of setting up
a conference prior to connecting all parties together or to consult with both parties prior to transferring a
call. The display also toggles between the two parties. This is not available on attendant consoles.
Selective Conference Party Display, Drop, and
Mute
Selective Conference Party Display, Drop, and Mute allows any user on a digital station with display or
on an attendant console to use the display to identify all of the other parties on a two-party or conference
call. The user presses a feature button while on the call that puts the station or console into conference
display mode. The user then can scroll through the display of each party currently on the call by
repeatedly pressing the feature button. The display shows the party's number and name (when available).
