To use the Communication Manager software, you require a valid Communication Manager license file. Without a valid license file, Communication Manager enters the License Error mode, with a 30-day grace period.
  • Prior to Communication Manager R10.2.1.1, if the 30-day grace period expires before a valid license file is installed, Communication Manager enters the License Restricted mode. In this mode, the Communication Manager blocks only the system administration activities.
  • Beginning with Communication Manager R10.2.1.1, if the 30-day grace period expires before a valid license file is installed, Communication Manager enters the License Restricted mode. In this mode, the Communication Manager blocks call processing, including emergency calls, and system administration activities. This is applicable only for Main Communication Manager server. For Enterprise Survivable Server (ESS) and Local Survivable Processor (LSP), only the system administration activities is blocked.
Communication Manager uses the Avaya PLDS or Product Licensing and Delivery System to manage license entitlements and generate license files. The license file contains information regarding the product, major releases, license features, and capacities. Avaya PLDS provides the ability to move licenses between Communication Manager servers if the support offer and the move policy are followed.
Communication Manager uses the Service Pack and Dot Release Guardian technology to protect and control the authorized use of service packs and dot releases. Using this technology, Communication Manager inserts the Support End Date (SED) in the license file and compares it with the publication date of the service pack or the dot release, thus, preventing the use of a service pack or a dot release that has a publication date after the SED.
