confused: the same thing just happened to me.

Call rang... I picked it up... it made a computer sounding chime and then hung up on me... As if I was being counted.  Once the chime was done... so was the phone call and then it hung up.  WTF?  Came up on caller I.D. with RD CRS...

Did not ring long enough for me to answer (must have disconnected after twice). Can't find info on the number except for land line location is in Euless, TX.
