Just got a call from here, actually a live caller.  But if I hear a lot of background conversations from a number unknown to me I always hang up.

Lot of static in the background and then I heard a "beep" which was cue to hang up. It was typical of when a telemarketer/Spam is calling and waiting for you to say hello before they  click over and begin speaking. Blocked!

called, left no message, blocked.
