1. 9 Authorization and Usage Indication interface Overview of the Authorization and Usage Indication interface The Authorization and Usage Indication interface is an XML over HTTP mechanism modeled on the ETSI TS 101 321 Open Settlement Protocol OSP for authorization and usage exchange An authorization request is made at the start of the session or call and before the session is started or the call is answered The subsequent authorization response sent in the HTTP response can e Authorize the call e Modify the DNIS of an authorized call e Deny the call Modifying the DNIS of an inbound call allows the platform operator to hide private number ranges by manually replacing the local number with the original assigned number At the end of the session or call the VoiceXML Interpreter dispatches a call detail record CDR that contains the following information about a call e Time the call started e Time the call ended e Length of the call e Transferred call information A usage response is sent in the HTTP response to a usage indication request If there is a problem sending this response the VX Integrated Media Platform writes call detail records CDRs to the local disk This occurs when the billing server is temporarily unavailable For information see Call detail records on page 105 Dialogic 97 Authorization and Usage Indication interfaceDialogic Vision VX Integrated Media Platform User s Manual Message form
