I am a single user with one extension. I have in my blocked call list 160 numbers and area codes with most of them as duplicates. When I select a blocked number and then click the "delete" key for that number, nothing happens. I even scroll to the bottom of the page and select "save" my changes but the duplicate number still appears in my blocked call list. It's the same issue with blocked area codes.
What is the proper format to enter to block a specific area code? is it just the 3 number area code or the number 1and then the 3 number area code?
