A control method of telephone user call is provided, which includes the following steps. A telephone user makes a call, and transmits a calling message to a corresponding processing device. The processing device extracts calling information of the user from the calling message, compares with a trap identification (trap ID) database, and determines whether a called number matches with one of the trap IDs in the database. If the called number does not match with any of the trap IDs, the call continues. If the called number matches with one of the trap IDs, the processing device notifies the query result and warning information to the user. The present invention can prevent the user from dialing a trap telephone number effectively, and avoid economic loss generated unconsciously.
