Managing MultiMedia Calling
Enhanced Mode MM Complex
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
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.
T.120 Data conferencing is made possible through the Extended Services Module (ESM) server, which is
an adjunct to the Avaya DEFINITY® Server. Up to six parties may participate in a single data
conference, and up to 24 parties may use ESM facilities for data collaboration at any given time.
The following steps add data sharing to a video conference:
1
Set up a multimedia conference.
2
Once a multimedia call is active, any member can initiate data collaboration by pressing the
mm-datacnf button. Or, to use the feature access code to initiate a data conference, press the
Transfer button. A second line-appearance becomes active and you hear dial tone. Dial the
multimedia data conference feature access code. Confirmation tone is heard and the system
automatically reselects the held call appearance of the multimedia conference. Avaya
Communication Manager will select an MLP data rate acceptable to all H.320 DVC systems in
the current call.
If the system does not have sufficient ESM server resources available for all parties currently in
the call, activation of T.120 data sharing will be denied. The mm-datacnf status lamp will flash
denial or the mm-datacnf FAC will produce reorder.
3
Each H.320 DVC system in the conference call is joined to the data conference. On many DVC
systems, the provided GUI may prompt the user with a dialog box, requesting the user to select a
specific conference to join. With MMCH, there should only be one conference available to select.
4
The user must now use the PC's GUI to begin application sharing. The method for beginning
application sharing or file transfer is different for each H.320 multimedia application. One of the
H.320 DVC systems activates data sharing from the H.320 DVC vendor provided GUI. See your
H.320 DVC system documentation for details.
5
The same H.320 DVC system as in step 4, opens an application, whiteboard, etc. to share and the
image of the application is displayed on all H.320 DVC systems in the conference.
For details on how multiple users may control the shared application, see the vendor provided
documentation for your specific H.320 DVC system.
