Understanding The Multimedia Complex - Avaya Communication Manager Administrator's Manual

Understanding the Multimedia Complex

When a vector is used to route video (56K/64K) calls to a hunt group comprised of data
extensions, the vector must have the Multimedia field set to n. This field causes multimedia
calls routed through the vector to receive early answer treatment prior to processing the vector
steps. This provides a talk path to the caller for announcements or immediate conversation with
an agent and starts network billing for the incoming call when vector processing begins.
Understanding the Multimedia Complex
1-number access
1-number access permits originating users to make voice or multimedia calls to a Basic
multimedia complex by dialing the same number for either type of call. The number may be the
voice station extension or the data module extension. If the incoming call is a voice call, Avaya
Communication Manager directs it to the telephone. If the incoming call is 56K or 64K data call,
Avaya Communication Manager recognizes it as such and sends it to the multimedia endpoint.
Likewise, if a voice call is addressed to the data extension, the system recognizes this and
directs the call to the voice station.
Calls originating on the same server as the Basic mode complex destination may always use
1-number access for voice or video. In order to take advantage of 1-number access for calls
originating from a remote location, the incoming calls must arrive over ISDN-PRI trunks. If the
system is setup with separate data non-PRI digital facilities multimedia calls must be made to
the data extension.
AVD (alternate voice/data) trunk groups cannot be used to provide 1-number access with
MMCH. If the AVD trunk group has a BCC of 0, all calls arriving over the AVD trunk to the Basic
mode complex will be assumed to be voice calls. If the AVD trunk group has a BCC of 1 or 4, all
calls arriving over the AVD trunk to the Basic mode complex will be assumed to be multimedia
calls.
Originating voice calls
All voice calls are originated at the voice station.
Originating multimedia calls
For a Basic mode complex, multimedia calls are normally originated at the user's multimedia
equipped PC. These multimedia calls use the associated station's COR/COS.
