Hmmmm, got the first call (that i remember) from this number today about noon.  While I was reading these posts, got a second call...  answered and there was no one there ... except you could hear someone faintly...  I said  hello about 6 times and then a guy asked for Sarah... no one here by that name.... he sounded like he couldn't read...  anyway, told him no one here by the name he was looking for and he hung up.  we'll see if he calls back tomorrow.
