got the same prob. 3 or 4 times a day. sometimes i don't say anything and it will stay connected for a few seconds longer and then hang up. if i say hello immediately, it hangs up immediately. weirdest thing ever. sure wish there was a solution. i am about to try calling my carrier and having the number blocked.
I've received a few calls from this number also, 225-000-0000. I got one Friday, one Saturday, and one today (Monday). Nobody says anything and there are no sounds on the other end. They hang up after I say 'hello' a couple of times. I live in Louisiana, though, so I recognize the area code 225 as the one I live in within Baton Rouge. Are people receiving calls from this same number who are not in or from Louisiana?
