I said Hello but no one responded.

got a call..same as above answered but no response...

Got another call early in the morning, 6:12AM, picked up the phone and no one responded.  This is getting to be frustrating and very annoying with these calls like they are checking to see if anyone is at home.  Wish they would stop, especially early morning???? what is with that?
