Various IP Office features and applications require entry of licenses into the system's configuration. The licenses are
unique 32-character codes based on the feature being activated and the serial number of the feature key dongle 190 installed with the IP Office system.
The serial number is printed on the feature key dongle and prefixed with FK. It can also be viewed in the system configuration using IP Office Manager.
· For IP500 V2 systems, the feature key dongle takes the form of an SD card inserted into the control unit. The card is a mandatory item for these systems even if they use no licensed features.
