The CG number is a numeric identifier for this enterprise
contact center application CTI gateway. This is a user-
defined numeric value and may not be identical to the table
index. The value is limited by the contact center application
to a value between 1 and 80 as this is the maximum number of
CTI gateways supported by the application.
This object has been deprecated since its range is now
inappropriate; the number of CTI gateways supported in a
deployment increased to 150 in ICM/CC version 7.5 and again
up to 250 in ICM/CC version 8.0.
