Simply CallerID is a simple, but full featured callerID program. At only $7.00, the program is by far the most affordable on the market. Includes Datenbank logging, aliasing, call blocking and various forms of notification that some of the more expensive programs do not have. The user can block incoming calls with the push of a button, or program the Dienstprogramm to automatically block certain numbers. Setup is easy, with a built in port tester to find an available comm port, and a CallerID modem command tester to find the proper command string for your modem.
