Called early in the morning, I didn't pick up. I don't pick up calls from unknown numbers. Wanted to check the number first.

Weird.  A call came and only rang twice.  I answer phones for a living, so I called back.  Recorded voice said "if you wish to be put on a do not disturb call for this number, press 1" - I hung up and blocked them.

Just called my office number.  I don't deal with out of County groups, so knew it wasn't really for me, so I ignored it.  No message left

This number calls once in a while and leaves about a 3-minute musical interlude on the voicemail (sounds like a riff on a Sheryl Crow song) which I have to let play all the way through to delete.

I love this website! It allows me to confirm that a caller is SPAM so I can block it.

My phone company does not have a blocking service, so I use a Panasonic cordless phone system with a call blocking feature.
