U/K caller calls regularly from (410) 314-2952 but never leaves a message. When I redialed the number, recording says it's a nonworking number. I'm concluding it to be a telemarketer and Black Listed it in my directory. Now I just let it ring.
This number calls repeatedly, sometimes multiple times a day, even though we're on the Do Not Call registry. No one answers/it's a recording when we answer. When we call back we get a recorded message that the number is not in service.
