4. AA Service
If the VPS transfers the call using the AA service, the PBX will inform the VPS of the status of the called
destination with the preprogrammed DTMF status signal so that the VPS can confirm the status of the
extension without listening to the system tones (e.g., ringback tone).
Assign the DTMF status signal to suit the VPS settings.
