When using both Call Lists and Call Boards, having the ability to set the maximum number of call attempts per lead you can dial in a single day. For example, the rule of thumb is to not exceed 9 attempts to one lead per day, so, set call attempts per day to 9, and once 9 attempts is reached, within the calling hours of 8am to 9pm, it will not allow you to call that lead again until 8am the next day.
