I wish stupid numbers would not call and waste my time!  No answer or no voicemail.  

got a call from this number at 0600 this morning.   no voicemail left

looks suspicious

Called at 9:40 central time. Caller ID says number is from Los Angeles, CA. Didn't recognize the number, so didn't answer. Left no message.

This number called my cell phone.  I've blocked the caller from calling again and reported the number to the NSA.

Somehow this rang through on my iPhone despite my having it in Do Not Disturb mode at the time.  I've got it set so that if 2 calls come from the same number within a 3 minute period it will ring anyway, in case of emergency -- however my call log says this number called only once so I can't understand how it rang?  Anyway I don't know anyone in Los Angeles (which is where the caller ID was saying it came from) so I didn't answer. No voice mail left.  Called it back a few minutes later out of curiosity and conveniently "the mailbox associated with this number is full".  Hmm.  Blocking this number now.
