Configuration name

Activity Test

Applicable contexts

SS7 service

The Activity Test configuration determines when Sentinel will test for the continued liveness of a dialog that has had a period of inactivity.

During the active call period, Sentinel runs a timer where the duration is based on the Activity Test configuration. The timer is stopped each time Sentinel receives a message from the MSC such as an Apply Charging Report; and if the call is still active then the timer is restarted again. If the timer expires, Sentinel sends an Activity Test operation on the dialog to test that the connection to the MSC is still active. If the Activity Test fails, the session is terminated.

Note The configuration is in common with the SIP service. See Activity Test Configuration.
