Narrative:

On descent into medford, or, for ILS runway 14, we were instructed to descend from 8000 ft to 7000 ft. During descent, we got a GPWS aural warning. We executed GPWS avoidance maneuver of full power climb and 'current 'heading. We had been issued 170 degree heading to intercept localizer. A king air was in the area, currently 10 O'clock position, 5-6 mi, at 800 ft. As we climbed for GPWS event, we noted location of king air. We established communication with ATC facility and were given a heading to fly. At no time did we get a TCASII traffic warning. Vector for approach and flight terminated without further incident.
