NCR Corporation - in Maryland - try calling back  "number you are calling is no longer in service"  they are a computer programming, data processing and software development company -  unless they are calling to try and hire you I cannot figure out why in the world this company would be contacting the "general public"  their customers are BIG Box like Walmart and Best Buy,  Banks, etc...  

I got 6 calls in a matter of 15 minutes - and each time they hung up after the 2nd ring... maybe they are doing programming for the local telephone company...  really more annoying then anything else
