Licensing requirements

Last Updated : Jun 02, 2025 |
For licensing, Branch Session Manager and core Session Manager require:
  • Product Licensing and Delivery System (PLDS) for license entitlement management, license activation, and license file delivery.
  • Web License Manager (WebLM). Use WebLM that is embedded in System Manager.
You can download the license file from PLDS and install the license. Avaya or an authorized Business Partner can also download and install the license file.
Software licenses for upgrades to major releases of Session Manager are chargeable. Software licenses for upgrades to the next minor upgrade release are not chargeable.
The Session Manager license file contains the total number of authorized Session Manager licenses available for the enterprise. With Session Manager you can monitor the Session Manager licenses used in the system, based on the instance counts. Session Manager raises an alarm when the number of licenses used exceeds the number of authorized Session Manager licenses available for the system. The system does not block the calls or disable the feature. You can:
  • Purchase additional Session Manager licenses from Avaya.
  • Analyze the Session Manager license usage and reschedule the planned usage of the system.
Note:
Licensing provides a 30–day grace period for all license errors, including no license file present on initial installation, before applying any license enforcement.
