Before importing a large number of devices that support Call History recording, you must set the maximum call history records in the Dimension Selection form accordingly.
To determine the maximum number of call history records:
Identify the number of devices in the import file that support call history recording.
Multiply that number by
the device's default call history records value plus the number of call
history records that you wish to allocate to the device.
For example, if your import file contains 10 devices that support call
history recording, each device has a default call history value of 20,
and you wish each device to have a call history record value of 10, multiply
10 x (20 + 10) = 300. The maximum number of call history records is 300.
From the Selection menu, choose System Configuration.
Click System Capacity and then click Dimension Selection.
Click Change.
Ensure that the value in the Call History field in the Dimension Selection form is larger than the value obtained in Step 2 above. If it is not larger, enter the value you obtained in Step 2.
Click Save.
Proceed to Previewing and Importing the Spreadsheet.
CAUTION: The maximum number of call history records must not exceed the number of call history records allocated on a system-wide basis through the Dimension Selection form. For more information about system-wide dimensioning settings, see Dimension Parameter Defaults.
