Narrative:
Descending to cross somto at 13000 ft, passing through 15000 ft we received an RA to climb. We did, and advised ATC. Climbed to 17200 ft. A cpr jet appeared in our windscreen. Apparently he had climbed underneath us and popped out in front of us. It was too close for comfort and probably a TCASII save. Center said he was VFR phl (or pne) to teb. He leveled off at 17500 ft.
