Multiple Level Precedence And Preemption - Avaya Communication Manager Administrator's Manual

Location by Region
Location by Region provides a way to administer location by IP network region. This allows for the
correct date and time information and trunk routing based on the IP network region.
Location by Region allows you the ability to have an IP phone registered with a DEFINITY server, but
located at a site with a S8300 Media Server with a G700 or Remote Office endpoints, to display the
correct time and date worldwide. The IP phone can be administered in a different network region from
other Avaya Communication Manager endpoints, and in the same "location" as the S8300 Media Server
or Remote Office users. It allows IP endpoint users the ability to move from location to location and
always have correct display information. Remote users are identified in a network region and location
that routes them to correct 911 services or notifies them via announcements, that they are in a different
911 jurisdiction than the DEFINITY they are registered to.
Alerts/Interactions
911 Call Handling
Location by Region attempts to overcome a limitation in the emergency response system - USA Public
Safety Answering Points (PSAPs) currently have no good way to contact each other. Even if you are able
to speak, and you explain to a PSAP in one part of the country that you need help in another part of the
country, the 911 staff that you are talking to have no fast way to relay your comments to a PSAP near
where you are located. If you describe your location as out-of-state, you likely will to be told to hang up
and find a local phone.
Earlier 911 call handling features were unable to handle IP telephones because there was no way to pop
up a window on an IP telephone to let the IP telephone user know why their 911 call was blocked and
advise them on the right thing to do. Now, you can choose to dedicate one location to handle such
roaming IP telephones. That special location could have corresponding ARS routing tables that route all
911 calls to a repeating announcement saying something like "You are too far away from the office
switching equipment for the [name of the home location]'s public safety office to be able to help you.
Please call 911 from a local, circuit-switched phone."

Multiple Level Precedence and Preemption

Multiple Level Precedence and Preemption (MLLP) provides users the ability to assign levels of
importance to callers, and when activated, to give higher-priority routing to individual calls based on the
level assigned to the caller. The MLLP features include:
•
Announcements for Precedence Calling
•
Dual Homing - Allows a user to dial a telephone number and have the call route to its destination
over alternate facilities if the initial route is unavailable
•
End Office Access Line Hunting - Automatically hunts for an idle trunk over end office access
lines based on the precedence level of the call
•
Line Load Control
•
Precedence Calling
•
Precedence Call Waiting
