Calls regularly and leaves no message. Caller ID shows "Oso May."  

Also get same constant calls - and also shows "Oso May" on caller ID.  I'll never pick up now that I know others are getting them.  Clearly telemarketer or some sad soul.  

Caller ID from VAILAB U - does not leave a message. Have been several calls and doesn't help to be on "Do Not Call List!"

Here's one for the crossword enthusiasts… What's 8 letters, starts with OSO and ends with MAY?

I, too, get calls from Oso May that I don't pick up.  Today's call said Vailab U with this number on one phone but only "unknown caller" on the phone I picked up.  There was someone at the other end.  I wasn't welcoming, but the caller said my address and then, "I'll be over to your house in 15 minutes," which I took as a threat.
