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:
Currently, 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
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.
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.
