Keeps calling...all hours of the night.  They never leave a message.  
Can't figure out who it is.

i get phonecalls from this number as well. and never leaves a voicemall either and doesnt talk

Someone from this number has been calling me on a regular basis for the past five months, usually in the evening between 6pm-9pm.  They never leave a message and on the occasions that I have answered, they ask for someone who does not live here.  I have told them that there's no one here by that name and still they continue to call.

I am also getting calls from this number there is no one there or no message left

I have been getting phone calls from this number and today they actually left a message with my name...of course, it's a business phone where I have my name in the voice message. Just an FYI...
