Prerequisite Features

Optional: Any feature setting the UserReleaseCause session state field

The Release Call And Close Dialog feature is a very simple feature that instructs Sentinel to release the call or SMS and close the dialog with the MSC. The following release cause codes are used by default:

  • for calls:

    • when used during Initial Trigger handling: CLASS_1_CALL_REJECTED (21)

    • when used during End Session handling: CLASS_1_NORMAL_CALL_CLEARING (16)

  • for SMSes:

    • if the latest OCS reply (if any) indicates an unknown user, then: UNKNOWN_SUBSCRIBER (30)

    • otherwise: RESERVED (11)

If a different release cause code is needed, another feature can be run before the Release Call And Close Dialog feature to set the CCUserReleaseCause or CCUserReleaseCause session state variable. If this session state variable is set, the Release Call And Close Dialog feature uses the cause value it specifies instead of the default. If the value set is not within the valid range of cause codes, the default cause code as specified above will be used instead.
