FREE CALL Recipient Line Service Options

FREE CALL Number Notification

When making calls from a FREE CALL DX contracted telephone line, the FREE CALL number is displayed instead of the standard telephone number on the recipient device with a caller number display function.

  • 0077 FREE CALL numbers are not notified.
  • Applications are only accepted for lines being used as a FREE CALL DX recipient.
  • This service is available for use with KDDI Hikari Direct, au HIKARI Business, and NTT lines (analog/INS). However, the setting method is different for each line type. Also, if used for an NTT line, the title is "Specific Caller ID Display" function (the basic monthly fee will be billed from NTT East or NTT West).
  • KDDI will separately provide information regarding actual usage of this service, such as setting method, after confirming the details.
  • For details about prices, refer to the pages for FREE CALL incoming line services at the links below.
