Enhancement on-hold positions COMmander 6000

With this enhancement you can increase the number of on-hold positions (call parking) from the standard 10 to a total of 30.
On-hold positions are used to hold incoming calls that cannot be immediately put through to the recipient.
After parking, the switchboard/reception is free again and can take further calls.
As soon as the target person can be reached, he or she can independently answer the parked call by retrieving the on-hold position.
