License file for Communication Manager

Last Updated : Jun 10, 2026 |

Use the Avaya Product Licensing and Delivery System (PLDS) to generate and download license files for Communication Manager.

PLDS is an online, web-based tool for managing license entitlements and electronic delivery of software and related license files.

After you obtain the license file, use System Manager WebLM to install the license file. System Manager WebLM is a web-based application for managing licenses and is installed as a part of System Manager.

The license file is an Extensible Markup Language (XML) file. The license file has the information regarding the product, major release, and license features and capacities.

You must install license files for the Communication Manager main server, but not for survivable servers. Survivable servers receive licensing information from the main server.

A 30-day grace period applies to new installations or upgrades to Communication Manager, Collaboration Server, and Solution for Midsize Enterprise. You have 30 days from the day of installation to install a license file.

Duplicated server licensing

For a Communication Manager duplex configuration, install the Communication Manager license file on WebLM, assign the same license file to both active and standby servers on WebLM, and then configure the same WebLM URL on both servers.

Note:

One centralized license file should not be mapped to more than one Communication Manager. In case of duplex Communication Manager, both active and standby Communication Manager from that pair should be mapped to the same centralized license file.
