The PG number is a user-defined numeric identifier for this
enterprise contact center application peripheral gateway. The
value is limited by the contact center application to a value
between 1 and 80; 80 is the maximum number of peripheral
gateways supported by the application.
This object has been deprecated since its range is now
inappropriate; the number of peripheral 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.
