Who called from 4079355621

Same as previous posts - didn't answer call and when I called back got busy signal.

just got a call from (407) 935-5621
I answered, and the call ended.  I am getting annoyed as I have had a few calls like this, but i am on do not call list.
Tried to call back, but got a busy signal.

Received a call from this number. Did not answer, no message was left.

Same thing, missed call at 11:45 PT, no message...tried to call back, busy signal. Also on the do not disturb list, annoying!!

Yep, I do this same thing.  I also use YouMail, it is free and it adds them to a 'ditch list' so my phone never even rings when they call.  :)
