Managing MultiMedia Calling
Data Hotline
If endpoint software allows users to select the dial function without entering a number, the
endpoint can be used for hotline dialing.
Dial Access to Attendant
Access to Attendant is blocked for a data call from a Basic mode multimedia endpoint.
Data Trunk Groups
Data trunk groups may be used to carry H.320 calls of a fixed (administered) bearer capability.
Hold
The voice station and multimedia endpoint of a Basic complex are each independent devices
with respect to call control. When a Basic multimedia complex voice station executes hold only
the voice station is held. If the user has conferenced their multimedia endpoint into a multimedia
conference, activating hold will not disconnect the multimedia endpoint from the conference, it
will only disconnect the Basic multimedia complex voice station. Executing hold with an
Enhanced mode complex will fully disconnect voice and video from the current active call.
Hunt Groups using Basic Mode complexes
Since Basic mode complexes may receive point to point multimedia calls at the DVC system
and voice calls to the station simultaneously, the voice station extension may be placed in any
normal voice hunt group or ACD skill and the data extension may be placed in a simple hunt
group made up of only data extensions.
Basic mode complex data extensions or stand-alone data extensions may be used to create
simple data hunt groups. Data extensions are not allowed in ACD hunt groups. Avaya
recommends that you do not mix voice and data stations in a hunt group.
If you want multimedia calls to hunt to multimedia endpoints (i.e. 2B point to point data hunting),
put the data extension in the hunt group. If you place the voice extension in a hunt group, only
voice calls hunt to that extension. Multimedia calls to a hunt group with a Basic mode voice
station as the hunt group member will not be offered to the DVC system of the Basic mode
complex. If either the voice or data extension of a Basic mode complex is busy, the entire
complex is considered busy for hunting purposes.
In order to guarantee that all members of a voice hunt group or skill can receive voice or
multimedia calls, all members should have the H.320 field on the station screen set to y. Simple
voice stations and Basic complex mode voice stations will receive voice only. Enhanced mode
stations will receive voice and video.
The MM Early Answer field (on the Hunt Group screen) tells the system to answer the
incoming multimedia call and establish audio before it reaches the first member of the hunt
group. Thus, when the talk path is established, the caller is able to speak with an agent
immediately. This is not necessary for hunt groups comprised of data extensions.
