A method and system for efficiently recognizing the last digit of a computer-dialed DTMF telephone number. The actual gaps between a number of first-dialed successive digits are compared with a standard gap exhibited during computer dialing to determine whether the dialing in progress is manual or automatic. As dialing proceeds, the absence of a digit for a preset time indicates that dialing has been completed. The preset time is set to a small value if it is determined that computer dialing is in progress.
