Japan Toll-Free Numbers

Our Japan Toll-Free numbers are mapped to Direct Inward Dialing (DID) numbers.

Inbound call

Inbound calls to the Toll-Free number are forwarded to the customer's DID number. Therefore, the customer receives these calls to their DID number rather than the Toll-Free number.

Outbound call

Depending on the customer's Toll-Free number configurations, they can call using their DID number or both their DID and Toll-Free number.

  • If the customer is configured with a DID number, the end user will see the Toll-Free number as the Caller ID.
  • If the customer calls from a Toll-Free or DID number, the end user will receive the call with the same Caller ID as the From value in the call request.
