Managing multimedia calling

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.
6. To end the data collaboration session and retain the voice/video conference,
the station that selected the mm-datacnf button or FAC may press the
mm-datacnf button or hit transfer and dial the mm-datacnf deactivation
FAC.
NOTE:
As of this writing, many endpoints do not respond correctly to ending
the data 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 resources for the new endpoint. The new
endpoint will get voice/video and data sharing if the new endpoint supports the
MLP data rate chosen by the system when T.120 data collaboration was activated.
If the endpoint does not support the pre-existing MLP data rate, the new endpoint
will only receive voice and video.
Single switch data collaboration. When all parties involved in data
collaboration conference are located on the same physical Avaya DEFINITY
Server, there is no restriction on the type of user. The parties may be any
combination of Enhanced multimedia complexes, Basic multimedia complexes or
stand-alone H.320 DVC systems.
