For non-subscription system or network, the primary server needs a PLDS license file added. That license file is unique to the PLDS ID of the primary server and the major level of software (for example 11.x) that it is running.
Once the license file has been added, the licenses in that file need to be assigned:
Some licenses are assigned automatically to reflect the configuration of a particular server. For example, the user profile licenses are assigned to match the users on each system.
Other licenses are assigned manually. For example you can configure how many SIP channel licenses each system in the network can take from the total number available in the license file.
