If an important number happens to be busy, this application will recheck that number repeatedly for availability, for up to a user-set number of minutes. You simply press the dial button and provide the telephone number you want to call. If the line becomes free, you'll hear the ring signal. Just pick up your phone and start talking. You may also set the program to redial on ring signals too. This feature can be used for radio contests and call-in television voting.
