Chapter 92 Trunk Configuration
Trunk Configuration Settings
MLPP Indication If available, this setting specifies whether a device that is capable of
playing 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.
Call Routing Information
Inbound Calls
Significant Digits Significant digits represent the number of final digits that are
retained on inbound calls. Use for the processing of incoming calls
and to indicate the number of digits that are used to route calls that
are coming in to the H.323 device.
Choose the number of significant digits to collect, from 0 to 32.
Cisco Unified Communications Manager counts significant digits
from the right (last digit) of the number that is called.
Calling Search Space From the drop-down list box, select the appropriate calling search
space for the trunk. The calling search space specifies the collection
of route partitions that are searched to determine how to route a
collected (originating) number.
You can configure the number of items that display in this
drop-down list box by using the Max List Box Items enterprise
parameter. If more calling search spaces exist than the Max List Box
Items enterprise parameter specifies, the Find button displays next
to the drop-down list box. Click the Find button to display the Find
and List Calling Search Spaces window. Find and choose a calling
search space name by using the
Finding a Calling Search Space
procedure in the Cisco Unified Communications Manager
Administration Guide.
Note To set the maximum list box items, choose System >
Enterprise Parameters and choose CCMAdmin
Parameters.
AAR Calling Search Space Choose the appropriate calling search space for the device to use
when performing automated alternate routing (AAR). The AAR
calling search space specifies the collection of route partitions that
are searched to determine how to route a collected (originating)
number that is otherwise blocked due to insufficient bandwidth.
