Narrative:

Arrived in area at xa:35. Could not relieve anyone until my shift started at xa:45. A controller gave a relief briefing to no one and left the position. I had to work the unmanned sector prior to my shift start. The controller left a dummy jack plugged in and left the frequency in the ear. I noticed that an aircraft needed to be descended and handed off but there was no hand set. I found a hand set and gave the clearance. Received no response due to the frequency not selected to speaker. When I figured out the problem the pilot was extremely frustrated. There was no error but a very unsafe situation.
