Understanding the multimedia complex
Issue 5 October 2002 331555-233-506
If an Enhanced mode complex is the covering party, the answering voice station
will receive voice and video. If all voice stations in the coverage path have the
station screen Early Answer field set to
n and the originator of the multimedia call
was not a local Enhanced mode complex, the answering station will hear
hourglass tone.
Coverage: Multimedia calls and off-net call coverage. If the principal station’s
coverage path include a remote coverage point, the multimedia call will cover
off-switch as voice only. If the call is unanswered off-switch and proceeds to the
next coverage point on-switch, the multimedia nature of the call is preserved.
Coverage: Multimedia calls and coverage to voice mail. Voice mail systems
such as AUDIX are typically the last point in a coverage path and are usually
implemented as a hunt group. In order to guarantee that the originator of an H.320
multimedia call hears the voice mail greeting, the hunt group that defines the list
of voice mail ports should have the Early Answer field on the hunt group set to
y.
This field will have no effect on voice calls to the voice mail system.
Call Detail Recording. Each channel of a 2-channel call generates a separate
CDR record.
Data Collaboration
Once you have established a multi-point video conference, multi-point T.120 data
collaboration may be enabled for that call. This will allow all video parties on the
current conference to collaborate.
T.120 Data conferencing is made possible through the Expansion Services
Module (ESM) which is an adjunct to the Avaya MultiVantage. Up to six parties
may participate in a single data conference, and up to 24 parties may use ESM
facilities for data collaboration at any given time.
Adding data sharing to a video conference
1. Set up a multimedia conference.
2. Once a multimedia call is active, any voice station in the conference, can
initiate data collaboration by pressing the mm-datacnf button. Or, to use the
feature access code to initiate a data conference, press the Transfer button.
A second line-appearance becomes active and you hear dial tone. Dial the
multimedia data conference feature access code. Confirmation tone is
heard and the system automatically reselects the held call appearance of the
multimedia conference. The Avaya MultiVantage solution will select a data
rate which is acceptable to all H.320 DVC systems in the current call.
If the system does not have sufficient ESM resources available for all
parties currently in the call, activation of T.120 data sharing will be denied.
The mm-datacnf status lamp will flash denial or the mm-datacnf FAC will
produce reorder.
