  • If customer call back an incoming IDD call by retrieving the telephone number from the caller number display (e.g. from "Answered" or "Missed" call record), this IDD call will be charged at IDD 001 rates since you are using IDD 001 to make the call.
  • IDD call charges will apply once a call is answered (even if the call is answered by any automatic answering systems including announcement, tone machine, etc). In some circumstances, IDD call charges may still apply to the ringing time due to special call routing design of third party service providers in the event if a call is not answered.
