Behaviour

The feature checks if the trigger message is a TCAP Message,if it is then it analyses the components to determine if the Tcap Message contains either a SINGLE_COMPONENT_TYPE or MULTIPLE_COMPONENT_TYPES (TCOperationResult and TCOperationInvoke) and sets a session state field. The value of the session state field can then be used subsequently in feature scripts to select which features to run. The following excerpt demonstrates how the feature and session state field can be used in feature scripts.

SRI4SM_SipThirdPartyAccess_PartyRequest:
    FeatureScriptSrc: featurescript SipThirdPartyAccessPartyRequest {
        run IPSMGWMapProxy
        run DetermineTcapMessageComponents
        if session.TcapMessageComponents.MULTIPLE_COMPONENT_TYPES {
            run IPSMGWGenerateMTCorrelationId
            run IPSMGWStoreRoutingInfoCassandra mode "store"
            run IPSMGWAdjustRoutingInfoResponse
        } else {
            run IPSMGWStoreRoutingInfoCassandra mode "store"
        }
