Managing MultiMedia Calling
Service Link Mode - The service link is the combined hardware and software multimedia
●
connection between an Enhanced mode complex's H.320 DVC system and the Avaya
DEFINITY Server which terminates the H.320 protocol. A service link is never used by a
Basic mode complex H.320 DVC system. Connecting a service link will take several
seconds. When the service link is connected, it uses MMI, VC and system timeslot
resources. When the service link is disconnected it does not tie up any resources. The
Service Link Mode can be administered as either 'as-needed' or 'permanent' as described
below:
- As-Needed - Most non-call center multimedia users will be administered with this service
link mode. The as-needed mode provides the Enhanced multimedia complex with a
connected service link whenever a multimedia call is answered by the station and for a
period of 10 seconds after the last multimedia call on the station has been disconnected.
Having the service link stay connected for 10 seconds allows a user to disconnect a
multimedia call and then make another multimedia call without having to wait for the
service link to disconnect and re-establish.
- Permanent - Multimedia call center agents and other users who are constantly making or
receiving multimedia calls might want to be administered with this service link mode. The
permanent mode service link will be connected during the station's first multimedia call
and will remain in a connected state until the user disconnects from their PC's multimedia
application or the Avaya DEFINITY Server restarts. This provides a multimedia user with
a much quicker video cut-through when answering a multimedia call from another
permanent mode station or a multimedia call that has been early answered.
Multimedia Mode - There are two multimedia modes, Basic and Enhanced, as described
●
below:
- Basic - A Basic multimedia complex consists of a BRI-connected multimedia-equipped
PC and a non-BRI-connected multifunction telephone set. When in Basic mode, users
place voice calls at the multifunction telephone and multimedia calls from the multimedia
equipped PC. Voice calls will be answered at the multifunction telephone and multimedia
calls will alert first at the PC and if unanswered will next alert at the voice station if it is
administered with H.320 = y. A Basic mode complex has limited multimedia feature
capability as described in
- Enhanced - An Enhanced multimedia complex consists of a BRI-connected
multimedia-equipped PC and a non-BRI-connected multifunction telephone. The
Enhanced mode station acts as though the PC were directly connected to the
multifunction telephone; the service link provides the actual connection between the
Avaya DEFINITY Server and the PC. Thus, voice and multimedia calls are originated and
received at the telephone set. Voice and multimedia call status are also displayed at the
telephone set. An Enhanced mode station allows multimedia calls to take full advantage
of most call control features as described in
Multimedia Early Answer — Valid entries are y and n (default). This field lets you set this
●
telephone for early answer of multimedia calls. The system will answer the incoming
multimedia call on behalf of the station and proceed to establish the H.320 protocol. After
audio path has been established to the caller, the call will then alert at the voice station.
