Multimedia application server
interface
The Multimedia Application Server Interface provides a link between
Communication Manager and one or more Multimedia Communications
eXchange nodes. A Multimedia Communications eXchange is a stand-alone
multimedia call processor produced by Avaya. This link to Communication
Manager enhances the capabilities of each Multimedia Communications
eXchange system by enabling it to share some of the Communication Manager
features. In particular, the interface provides the following advantages:
■ Call Detail Recording (CDR)— The capture of call detail records so you
can analyze the call patterns and usage of multimedia calls just as
Communication Manager administrators analyze normal calls.
■ Automatic Alternate Routing/Automatic Route Selection (AAR/ARS) —
The intelligent selection of the most cost-effective routing for calls, based
on available resources and your carrier preference. The system may select
public trunks via DEFINITY Multimedia eXchange (MMCX)
■ Voice Mail Integration — You can access your EMBEDDED AUDIX or
INTUITYAUDIX voice messaging system from a Multimedia
Communication eXchange (MMCX).
Multimedia calling
Multimedia calls are initiated with voice and video only. Once a call is
established, one of the parties may initiate an associated data conference to
include all of the parties on the call who are capable of supporting data. The data
conference is controlled by an adjunct device called an Expansion Services
Module (ESM).
Multimedia call early answer on vectors and
stations
Early Answer is a feature applied to multimedia calls in conjunction with
conversion to voice. Early Answer:
■ Answers the data call
■ Establishes the multimedia protocol prior to completion of a converted call
■ Ensures that a voice path to/from the originator is available when the
(voice) call is answered
