General FeaturesFeatures Guide 45Integration, Automated Attendant (AA) ServiceDescriptionThis is one of the VPS Integration features.The Automated Attendant (AA) Service, provided by the VPS, answers incoming calls andthen routes the caller to the desired extension automatically.If AA Service Integration is enabled, the KX-TD500 System transmits the Call Status Code(busy, answered, ringing, disconnected, etc.) to an AA extension before sending the normalcall progress tones. These codes enable the VPS to immediately recognize the current status ofthe call and improve its call handling performance.To utilize the AA Service Integration, group multiple AA extensions together as an ExtensionGroup and assign the group type of it as "AA."Within an AA Group, an incoming call hunts for an idle AA extension in a circular way. Thisensures that callers who need the AA service can surely access it. Up to 128 AA Groups, eachconsisting of more than one extension in the same tenant, can be created in the system.By default, Extension Group #127 is assigned as AA Group.Automated Attendant (AA) ServiceAn AA extension answers incoming calls (extension, outside) and then transfers the caller tothe desired extension automatically.Integration Code (Call Status Code) TableCode(default)Call Status Sent to the Voice Mail Port When1 Ringback Tone The extension dialed is ringing.2 Busy Tone The extension dialed is busy.Outside CallExtension AA 1 AA 2AA X AA 3Extension Group(AA)VPSDIL 1:1, DISA, DID, DDI (ISDN),TransferSystemTIE
