When configured for both online and offline charging, it may be desirable to allow sessions to proceed when there is a communications outage with the OCS.

By default Sentinel VoLTE will end a session if there is no connection to the OCS, or there is a timeout waiting for a response from the OCS.

When the Determine Charging system feature’s configuration parameter ContinueCallOnOCSFailure is true, for a session that detects an OCS communication problem, the session will proceed:

  • but no further Ro communication will occur even if Ro communication is re-established

  • and Rf and CDRs will continue to track the session

  • except a midsession OCS failure for a conference call will still result in the session ending.
