In order to automatically investigate correspondence between a call connection datum indicated by an originating call and a locus which the originating call transits through in an intelligent network, a call connection testing device comprises a memory in which a call information accumulating device accumulates a plurality of call connection data as stored connection data. So as to make a display control unit control an output device for display of the locus, a key is produced by a referring device to indicate the call connection datum and to produce as a produced connection datum one of the stored connection data that is accessed by the key.
