No Sales Calls is for Caller ID users who are bombarded with sales calls because it screens unwanted callers and hangs-up on them. You may hang up on private or anonymous, unavailable, out of area or even payphone calls. An incoming call log is created and saved to a 'log.txt' file, allowing users to print call histories. If someone you know actually is 'Out of Area,' they can bypass this feature by calling-back within 60 seconds.
