Narrative:

I was working satellite at mci combined north and south (multiple frequencys). Traffic was extremely heavy and the position should have been split in the interest of safety. A B190 took a descent clearance meant for C210 on another frequency. I did not hear both aircraft respond to the clearance. I had approximately 13-15 aircraft on frequency at the time with constant coordination from 4 different towers; 1 approach control; and 2 different ZKC sectors. During this time; I was barely able to complete all work functions and had to tell multiple VFR aircraft to call back later; yet management wouldn't open another position for relief. Another factor was staffing. We were extremely short staffed during this time.
