3/20/15 1224p & 1240p. I too look @ caller id before I pick up now. I made a real call @ 1230. Then their call @ 1240 begin to feel like something knows when I make a call or are on the phone I do not go to call waiting. A friend suddenly is getting these also. Do they target an area then go on to another? Today I am checking out the last 7 calls that came to box in last  3 days. i agree they do not end. I do not answer as 2 of my friends have gotten upsetting calls---{ 1 did call the police}
