The Session Manager Element Manager collects, monitors, and logs the number of concurrent SIP sessions in the system. Since the total number of session licenses used is equal to the number of concurrent SIP sessions, you can use the SIP sessions count feature to monitor and report the number of session licenses being used by the system.

The system raises an alarm for the following conditions:

• For a single occurrence of an event when the number of concurrent SIP INVITE sessions exceeds the authorized number of session licenses.

• If the number of concurrent SIP INVITE sessions in use continues to exceed the number of authorized licenses. For this condition, the system raises a new alarm once every 24 hours until either the number of concurrent SIP INVITE sessions is reduced below the number of authorized licenses or the number of authorized licenses is increased to be equal to or greater than the number of concurrent SIP INVITE sessions.

  Note:

  The system raises an alarm if a valid license file is not installed on the system.

The SIP sessions count functionality enables historical analysis of SIP sessions count data for the system or the selected Session Manager instance. Using the SIP session count function, you can:

• generate graphs of the analyzed data.

• export the analyzed data as a report in the comma separated value (CSV) or XML format.

Using the generated reports, you can conduct a time-based analysis of the license use of the system.
