STATION CONFERENCE

Description
This feature allows an extension user to set up a conference with up
to six conferees (plus the originating extension), without the assistance
of the Attendant. The conferees may be any combination of extensions
and trunks. To originate a conference, an extension user first estab-
lishes a 2-patty call, then adds on the remaining conferees. Any exten-
sion in the conference with an appropriate COS may add additional
parties to the conference to a maximum of seven. If the originator
encounters a busy or unanswered extension number, he may flash the
switchhook to return to the conference. If after flashing out of the
conference, the extension hangs up, the extension will automatically be
recalled to the conference. If a CO trunk is to be added to the con-
ference and the number dialed is incorrect or unanswered, the calling
party must hang up to release the connection. The extension will
automatically be recalled to the conference.
Conditions
COS Option Number 49 (Station Conference) is mutually exclu-
l
sive with COS Option Numbers 48 (Broker's Call) and 98 (Transfer
with Privacy).
If a conference contains only trunks (i.e., all stations in the
l
conference hang up), it is possible to leave two trunks in the
conference alone but one must be a Non-CO trunk
A call may not be held or transferred by an extension in a
l
conference.
A maximum of 30 conferences may be active at one time.
l
Only one party may flash out of the conference at a time.

Handsfree stations may be conferees, but must have normal
l

will return to their idle mode.

l
Conference) in its COS.
