there seems to be no one on the other end...

same here. called twice

Same here - what I do is save the number on my cell phone under the name "Do Not Answer" so if they call back, I don't have to wonder. Once you save one number, you have to save the others as "office" "Pager" "Cell" or another designation.

Keeps calling and have no clue who it is and never leaves a message
