Narrative:
We were level at fl 290 when boston center gave us a descent to FL250. The first officer was the pilot flying and as he started the descent; we got the RA. I looked down at the TCAS and noticed traffic 800 feet below off the nose of the aircraft. I then looked up and saw the traffic coming straight towards us. The first officer stopped the descent and leveled the aircraft as the traffic passed under us. He said that it passed 600 feet below us on the TCAS. I told center about the RA and he apologized and said that it was his mistake. We continued on to destination.
