Loss plans
Loss plans determine the amount of loss (quieter) or gain (louder) applied on
calls. Usually, your system uses a pre-defined loss plan that is based on the
administered country code. In some circumstances, you may be able to change the
loss plan used by your system on a per trunk or per phone basis.
!
CAUTION:
The values in the loss plan can significantly affect the quality of service that
your users experience. Therefore, in order to change the loss plan you must
thoroughly understand loss plans and your particular configuration. Avaya
recommends that you seek technical assistance from Avaya before making
any modifications to the loss plan.
In order to be able to modify your loss plan, the Digital Loss Plan Modification
field must be set to
y on the System-Parameters Customer-Options screen, and the
Customize field must also be
y on the System Parameters Country-Options
screen. An Avaya representative must enable these fields for you.
The 2 Party Loss Plan page of the System Parameters Country-Options screen
allows you to set the gain or loss levels (in dB) between two parties on a call. Each
row on this screen is considered a different loss group. You can assign a loss
group to a particular phone or trunk by administering a value for the Loss Group
fields on the Station and Trunk Group screens. This allows you to use different
loss plans for different types of phones or different trunk groups.
The Tone and Conference Loss Plans page of the System Parameters
Country-Options screen allows you to set the gain or loss levels (in dB) between
all parties on a conference call, as well as the total gain or loss in a conference
based on the number of parties.
IP endpoints connected via hairpinning or direct IP–IP are not under the control of
the administrable loss plan.
Loudspeaker paging
You can connect Avaya MultiVantage to loudspeaker systems and allow users to
page from their phones. You can administer up to 9 separate zones (sets of
loudspeakers) on Avaya MultiVantage, so an announcement can be made to one
group or location without disturbing people who don’t need to hear the
announcement. Auxiliary trunks connect the speakers in each zone to ports on an
auxiliary trunk circuit pack.
