Managing MultiMedia Calling
The user may then activate HOLD on the second call appearance and reselect the first call
appearance or select a third call appearance and originate another call.
- creating a multi-party video conference
An Enhanced multimedia complex can create a spontaneous video conference in the same way
that a spontaneous voice conference is created. Given an active call, the user activates the
CONFERENCE button. This puts the current call on HOLD and activates a new call
appearance. The user makes a multimedia call according to the instructions for originating a
multimedia call and then selects CONFERENCE to combine or merge the two call
appearances. This results in a 3-way conference.
If all three parties are video equipped, then a 3-way video conference results. Conference
members see the current speaker on video. The current speaker sees the last speaker on
video. If one of the parties is not video equipped, then a 3-way audio conference exists and the
two video equipped parties have 2-way video. The CONFERENCE action may be repeated until
6 parties have been conferenced together. The 6 parties may be any mix of voice or video, local
or remote parties.
The following steps create a multi-party voice/video conference:
1. Enhanced mode complex station A originates a multimedia call to, or receives a multimedia
call from, party B. Station A and party B have 2-way voice and video.
2. Station A, activates CONFERENCE.
3. Station A originates a multimedia call (i.e. uses the mm-call button/FAC/etc.) and dials the
party to be added, Enhanced multimedia complex C.
4. Party C, answers the call from station A.
5. Station A selects CONFERENCE to complete the 3-way conference. Parties A,B and C will
be in a 3-way voice/video conference.
Note:
If party C is another Enhanced mode complex on the same Communication
Note:
Manager server as station A, station A does not need to indicate a multimedia
call prior to dialing the new party in step 3. While A consults with C, the call will be
audio only. When A completes the conference in step 5, party C's video will be
activated.
A multi-party video conference uses voice-activated switching to determine which parties are
seen. The current speaker is seen by all other parties. The current speaker sees the previous
speaker.
Additional voice or video parties may be added by repeating these steps.
Data Collaboration
Once you have established a multi-point video conference, multi-point T.120 data collaboration
may be enabled for that call. This will allow all video parties on the current conference to
collaborate.
