Activity Test |
|---|---|
Applicable contexts |
SIP service |
The Activity Test configuration determines when Sentinel will test for the continued liveness of a SIP session 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 external SIP UAC/UAS; and if the call is still active then the timer is restarted again. If the timer expires, Sentinel sends re-Invite messages to test that the connection to the external SIP UAC/UAS is still active. If the Activity Test fails, the session is terminated.

The configuration is in common with the SS7 service. See Activity Test Configuration. |
