This one called my number twice within an hour on DEC 16.  They left no message but I could hear someone holding on for several seconds before hanging up.  This can't be legitimate.  I don't recognize the number and so far it looks like I am the first to report it to this site.  Looks to me like some telescammer has spoofed himself a new number.  Watch out everyone!  Now let's all report this number to the guardians of the Do Not Call List so nothing will happen and the scammer will spoof another number in a week or two.  Happy Holidays to all!

This number calls my home phone often. I let all home phone calls go to voice mail. They never leave a message.

This number has called me several times and never leaves a message. Really annoying.

This number has called several times and has not left a message. I called it back and was automatically put on hold with a recording that said that my "wait time is less than 1 minute."  I waited about 2 minutes but no one answered.

This number called me 4 times within the past 2-3 weeks, but they never left a voicemail every time I didn't pick up. On the 4th call (today) I decided to pick up and there was what appeared to be heavy breathing on the other side for about 28 seconds and then they hung up.
I immediately blocked the number.
