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 DEFINITY ECS, 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.
Multi- switch data collaboration. When all parties involved in data
collaboration conference are
not located on the same physical DEFINITY ECS,
the parties located on the DEFINITY ECS hosting the data conference (i.e. the
switch that activated mm-datacnf) may be any combination of Enhanced
multimedia complexes, Basic multimedia complexes or stand-alone H.320 DVC
systems.
All parties on remote switches must not be Enhanced multimedia
complexes:
they must be Basic multimedia complexes or stand-alone H.320
DVC systems. Prior to originating or receiving a multimedia mode call, the
mm-basic feature button or feature access code can be used to dynamically change
an Enhanced mode complex into a Basic mode complex and back again.
Forwarding of voice/multimedia calls. In Basic mode you can forward calls
from either the telephone or the multimedia endpoint. To forward a call from the
multimedia endpoint:
1. At the PC’s multimedia application, enter the call-forwarding feature
access code (FAC)
2. Enter the forward-to number in the dialed number field on the endpoint
software
3. Click the Dial button (or equivalent)
NOTE:
The PC multimedia software will probably respond with a message that the
call failed, since it does not recognize the FAC. In fact, DEFINITY ECS
does receive the message, and forwards all multimedia calls addressed to the
1-number.
