DescriptionField
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 preempt calls in progress when
it places an MLPP precedence call.
• Forceful—This device preempts calls in progress when it places
an MLPP precedence call.
Do not configure a device with the following combination of
settings: MLPP Indication is set to Off while MLPP Preemption
is set to Forceful.
Note
MLPP Preemption
Enter a hexadecimal value for the MLPP domain that is associated with
this device. Ensure that this field is blank or a value between 0 and
FFFFFF.
MLPP Domain (e.g., “0000FF”)
H.323 Device Information
The value designates the H.225 signaling port that this device uses.
The default value specifies 1720. Valid values include 1 through 65535.
Signaling Port
This check box applies only to video endpoints that receive a call. If
this phone receives a call that does not connect as video, the call tries
to connect as an audio call.
By default, the system checks this check box to specify that the sending
device should immediately retry a video call that does not connect as
an audio call prior to sending the call to call control for rerouting.
If you uncheck this check box, a video call that fails to connect as video
fails to call control. At this point, call control reroutes the call within
the route list. If Automatic Alternate Routing (AAR) is configured and
enabled, call control also reroutes the call between route lists.
Retry Video Call as Audio
By default, the system keeps this check box checked to specify that
Cisco Unified Communications Manager should initiate capabilities
exchange. This check box specifies that the Cisco Unified
Communications Manager needs to receive the far-end H.245 Terminal
Capability Set before it sends its H.245 Terminal Capability Set.
