Initiate ad hoc conferences in the following ways:
- Press the Conference
(Confrn) softkey, dial another participant, and press
Confrn softkey again to add the new
- Join established calls by
If sufficient streams are available on the conference
device, the conference controller (or other participant in the case of advanced
ad hoc conferencing) can add up to the maximum number of participants that is
specified for ad hoc conferences to the conference. Configure the maximum
number of participants for an ad hoc conference with the Maximum Ad Hoc
Conference service parameter in the Service Parameter Configuration window.
Cisco Unified Communications Manager supports multiple, concurrent ad hoc
conferences on each line appearance of a device.
Using Conference Softkey for an Ad Hoc Conference
When a user initiates a conference call,
Cisco Unified Communications Manager places the current call on hold, flashes the
conference lamp (if applicable), and provides dial tone to the user. At the
dial tone, the conference controller dials the next conference participant and
presses the Conference softkey to complete the conference.
Cisco Unified Communications Manager then connects the conference controller, the
first participant, and the new conference participant to a conference bridge.
Cisco Unified IP Phone display reflects the connection to the conference.
The conference controller (or other participant in the case
of advanced ad hoc conferencing) can drop the last conference participant from
the conference by pressing the
RmLstC softkey on the
Cisco Unified IP Phone 7960 or 7940. The conference controller (or other participant
in the case of advanced ad hoc conferencing) can also remove any conference
participant by pressing the
ConfList softkey to display the list of
participants, highlighting a participant, and pressing the
Remove softkey (only visible after you press the
A conference participant can view the list of conference
participants by pressing the Conference List (ConfList)
softkey and can drop the last conference participant from the conference by
pressing the Remove Last Conference Party (RmLstC)
softkey on the
Cisco Unified IP Phone. If a conference participant transfers the conference to
another party, the transferred party becomes the last conference participant in
the conference. If a conference participant parks the conference, the
participant becomes the last party in the conference when the participant picks
up the conference. When only two participants remain in the conference,
Cisco Unified Communications Manager terminates the conference, and the two
remaining participants reconnect directly as a point-to-point call.
Participants can leave a conference by simply hanging up. In
basic ad hoc conferencing, a conference continues even if the conference
controller hangs up, although the remaining conference participants cannot add
new participants to the conference. In advanced ad hoc conferencing, a
conference continues even if the originator hangs up, and any remaining
participant can add new participants.
Conference by Using
The user initiates an ad hoc conference by using the Select
and Join softkeys. During an established call, the user chooses conference
participants by pressing the
Select softkey and then presses the
Join softkey, making it an ad hoc conference. Up
to 15 established calls can be added to the ad hoc conference, for a total of
Cisco Unified Communications Manager treats the ad hoc conference the same way as
one that is established by using the Conference softkey method.
The Join Across Lines feature allows the user to join conference
participants across different lines-either on different directory numbers, or
on the same directory number but on different partitions. The Maximum Ad Hoc
Conference Service Parameter controls the maximum number of established calls
that can be added to the conference.
Conference by Using
You can initiate a conference by pressing the
cBarge softkey, or if the Single Button cBarge
feature is enabled, by pressing the shared-line button of the active call. When
cBarge is initiated, a barge call gets set up by using the shared conference
bridge, if available. The original call gets split and then joined at the
conference bridge. The call information for all parties gets changed to
The barged call becomes a conference call with the barge
target device as the conference controller. It can add more parties to the
conference or can drop any party.
When any party releases from the call, leaving only two
parties in the conference, the remaining two parties experience a brief
interruption and then get reconnected as a point-to-point call, which releases
the shared conference resource.
