The IP Office system requires licenses for some features, see Licenses. The license file can be either uploaded manually or pre-loaded onto the System SD card.
How is the system licensed?
•An XML file containing the full set of PLDS licenses is uploaded to the system. The license file is unique to the feature key serial number of the System SD card installed in the system.
•The card's ID number is printed on the card's label after PLDS ID, FK SN or FK depending on the age of the card. On newer cards is a 12-digit number. Older cards may have a 10-digit number. For PLDS licensing, use the 12-digit number. On older cards, for licensing, prefix the 10-digit number with 11.
Minimum License Requirements
For IP Office Basic Edition mode, new systems with no licensed features do not require any license to operate. However, if any license features are required, a Basic Edition system license is also needed.
