The present invention relates to a call authentication method using a one time outgoing number. According to the present invention, the call authentication method using a one time outgoing number wherein the method is implemented by a server linked with a user terminal and a call server, comprises the following steps: a first step of checking a user phone number to be connected; a second step of selecting a one time outgoing number to be mapped onto the user phone number or checking a selected one time outgoing number; a third step of mapping the selected one time outgoing number onto the user phone number and storing the numbers; a fourth step of displaying the one time outgoing number as a user-dedicated outgoing number on the user terminal; a fifth step of providing the selected one time outgoing number and the user phone number to the call server; a sixth step of receiving authentication data, which includes a call server-side outgoing number and a call server-side incoming number, for the line coupling a first call connection and a second call connection from the call server if the line of a request for the first call connection, which contains the one time outgoing number as a user-dedicated outgoing number and the user phone number as an incoming number, and the line of a request for the second call connection which contains the user phone number as an outgoing number and the one time outgoing number as an incoming number coupled together through a communications company server linked with the call server; and a seventh step of authenticating whether the call server-side outgoing number matches the user phone number and the call server-side incoming number matches the one time outgoing number. |
