If Communication Manager detects an error with the licensing, for example, license file is not installed, feature usage exceeds license capacity, or software publication date is after the SED in the license file, the Communication Manager server enters in license error mode, raises a major alarm, and starts a 30-day license grace period. During the 30-day license grace period, Communication Manager provides full normal operations.

• If the license grace period expires before the license error is resolved, Communication Manager enters no license mode.

  • 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.

• If the license error is resolved either before or after expiration of the 30-day grace period, Communication Manager returns to license normal mode.
