Managing MultiMedia Calling
mm-datacnf - Pressing the mm-datacnf button from any voice station that is participating
●
in a multimedia call will light the status lamp and alert the Avaya DEFINITY Server that you
want to enable T.120 data collaboration with the other parties on the call. The button status
lamp will also light for other participants in the multimedia call who have mm-datacnf
buttons.
Pressing this button from the voice station that enabled data collaboration on a multimedia
mode call will deactivate the data session and revert to a voice and video call. If you are
participating on a multimedia call with data collaboration, but did not initiate the data
collaboration, and you press this button, the status lamp led will flash momentarily and the
T.120 data services will not be terminated, (only the station that activated the collaboration
session can deactivate it). This button only works for stations connected to an Avaya
DEFINITY Server equipped with an ESM adjunct.
mm-cfwd - The mm-cfwd button allows a user to indicate that multimedia mode calls will
●
be forwarded as multimedia mode calls to a specific forwarded-to destination. If voice call
forwarding is active and multimedia call forwarding is not active then multimedia calls
going off of the Avaya DEFINITY Server will be forwarded as voice only calls.
The mm-cfwd button status lamp will be lit to indicate that multimedia call forwarding is
activated. Pressing the mm-cfwd button when the lamp is lit will deactivate multimedia call
forwarding.
Note - pressing the mm-cfwd button is the same as dialing the regular call-fwd FAC followed
by the mm-call button or FAC followed by the desired forwarded-to extension digits.
mm-multinbr - The mm-multinbr call button is similar to the mm-call button. It allows
●
origination of a multimedia call from any voice station. It is used when the destination
being dialed requires a different address for each of the 2 B-channels. An example of this
is Central Office provided ISDN-BRI. This type of BRI line is provisioned with separate
listed directory numbers for each B-channel. In order to make a 2B multimedia call to such
a device, two sets of address must be entered.
Originating a multimedia call with the mm-multinbr button will originate a call according to
the Default Multimedia Parameters selected on the System Parameters Features screen.
This default parameter will be either 2x56 or 2x64. The bearer capability of the multimedia
calls will either be 56K or 64K and the bandwidth will be 2B channels.
