This number called me at 2:43 pm on August 23. Caller ID said "Qualit Data". I was out of town for several days so I am not sure if they left a message or not (my machine is old and does not indicate which message came from which number)
Whoah -- weird -- exactly one year later I'm reporting again on this number. This time a live (as opposed to recorded, not dead!) woman's voice said she was calling for <my name> regarding a brief health care survey. I am pretty sure I know what doctor's office it is for.
