A call routing method for identifying an intra-lata call and an inter-lata call and a user interface method of an auto dialer are provided to transmit only an inter-lata call to a connection device for a long distance call by accurately grasping whether an originating call is an inter-lata call, thereby enabling a user to use a telephone service without time and costs. When a lata code of a searched record is different from a lata code of an caller number, the lata code of the searched record is determined as an inter lata call. And a long distance call connection access code and an inputted receiver phone number are combined. And the combined telephone number is transmitted. When the same record as LSC of the receiver telephone number is not searched, the long distance call connection access code and the input receiver phone number are combined. And the combined phone number is transmitted. |
