Managing MultiMedia Calling
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 can control the shared application, see the vendor
provided documentation for your specific H.320 DVC system.
6. To end the data collaboration session and retain the voice/video conference, the station that
selected the mm-datacnf button or FAC can press the mm-datacnf button or press
Transfer and dial the mm-datacnf deactivation FAC.

collaboration session and retaining voice/video. Some H.320 DVC systems drop
the entire call. Avaya recommends that once T.120 data sharing has been
enabled for a conference, that it remain active for the duration of the conference
call. When all endpoints have dropped from the call, the T.120 resources will be
released.
Joining a multimedia conference after T.120 data sharing has been enabled.
If a multimedia conference with T.120 data sharing is already active and it is desired to
conference in a new video endpoint, the new video endpoint can be conferenced into the
existing call. The new endpoint will be allowed into the data conference if there exists sufficient
ESM server resources for the new endpoint. The new endpoint will get voice/video and data
sharing if the new endpoint supports the data rate chosen by the system when T.120 data
collaboration was activated. If the endpoint does not support the pre-existing data rate, the new
endpoint will only receive voice and video.
Activating HOLD while on a T.120 data collaboration conference.
If an Enhanced multimedia complex is active on a multimedia call and the call has activated
T.120 data collaboration, the user should be receiving voice/video and data. If the station places
this existing call on hold, audio and video will be disconnected for the current call. The data
collaboration portion of the call will remain intact and unaffected. While this T.120 data
conference is on hold, the user will only be allowed to receive audio on all other call
appearances. Thus a user is limited to one call appearance that has T.120 data collaboration
active.
