AAR Group Choose the automated alternate routing (AAR) group for this
device. The AAR group provides the prefix digits that are used to
route calls that are otherwise blocked due to insufficient bandwidth.
An AAR group setting of None specifies that no rerouting of
blocked calls will be attempted.
MLPP Domain From the drop-down list box, choose an MLPP domain to associate
with this device. If you leave the value <None>, this device inherits
its MLPP domain from the value that was set for the device pool of
the device. If the device pool does not have an MLPP Domain
setting, this device inherits its MLPP Domain from the value that
was set for the MLPP Domain Identifier enterprise parameter.
MLPP Indication Some devices do not make this setting available. If available, this
setting specifies whether a device that plays precedence tones will
use the capability when it places an MLPP precedence call.
From the drop-down list box, choose a setting to assign to this
device from the following options:
• Default—This device inherits its MLPP indication setting from
its device pool.
• Off—This device does not handle nor process indication of an
MLPP precedence call.
• On—This device does handle and process indication of an
MLPP precedence call.
Note Do not configure a device with the following combination of
settings: MLPP Indication is set to Off or Default (when
default is Off) while MLPP Preemption is set to Forceful.
MLPP Preemption Some devices do not make this setting available. If available, this
setting specifies whether a device that is capable of preempting calls
in progress will use the capability when it places an MLPP
precedence call.
From the drop-down list box, choose a setting to assign to this
device from the following options:
• Default—This device inherits its MLPP preemption setting
from its device pool.
• Disabled—This device does not allow preemption of lower
precedence calls to take place when necessary for completion
of higher precedence calls.
• Forceful—This device allows preemption of lower precedence
calls to take place when necessary for completion of higher
precedence calls.
Note Do not configure a device with the following combination of
settings: MLPP Indication is set to Off or Default (when
default is Off) while MLPP Preemption is set to Forceful.
