How can I check the number of outbound calls made and exclude where two attempts have been made for one requester. E.g. if I know my team has 200 calls booked in a week for 200 different customers, how can I check to see if 200 calls were attempted to 200 different customers, the dataset I currently have includes a higher number as I believe it counts when more than 1 attempt was made to a customer, therefore I'm getting 230 outbound calls rather than a number closer to 200
