Dial number processing device, dial number processing method, dial number processing program, and dial number search device

摘要

The load on the user is decreased and convenience is improved by supplementing or correcting the dial number on the network side in the event that the user makes a mistake concerning the dial number. International telephone identification numbers that may be wrongly input are stored in a storage section (11) in correspondence with the corresponding correct number. When the plurality of leading digits of the dial number that is input from a telephone terminal coincides with a number that is stored in the storage section (11), a number substitution section (12) replaces the input dial number by the correct number. In this way, when a call is originated by a roaming user, if a wrong dialling code is identified, the call may be continued by substituting the correct dialling number.
