Called no message.  Hit the red button of death on my caller block box so will never hear from this number again.  I'm getting 30 calls a day now from various numbers--some blocked (I can see them on my caller ID even though they don't ring through).   And these calls are NOT benign annoyances.  I've needed to conduct much business regarding real estate on my home phone for the past two weeks and TWICE very important calls came in while these spammers had my number engaged while leaving a voice mail on my home answering machine--my preferred message storage.  And calls that come in when my number is engaged default (I can't alter it) to my telephone company  voice mail box.  As a result I missed TWO very important calls in one day while they had my phone line tied up!  And I didn't realize they'd come in. Fortunately, I picked up the receiver within a half hour of the calls shunted to VM and heard the beep sound telling me I had a voice mail message.  So called in and there was the call I'd been waiting for--that these horrid spammers had interfered with real calls by engaging my line and forcing the call on a 'busy" signal into phone company voicemail.  Now every time one actually comes through and gets onto my home answering machine I have to check VM to see if I missed a call that went to VM due to a busy signal!  These people are creating a nightmare.  I've missed TWO important business calls now because these spam calls are so frequent all day long it's not hard for real callers to get a busy line and get shunted to a voice mail box.   These calls are NOT just annoying.  They are impeding business.
