Narrative:
Aircraft X was ssebound from lex to atl via direct vxv MACEY2, and level at FL210. I was working at ZTL sector 41 (sfc -- FL230, in the vicinity of csv, crossville, tn). At approximately XA50Z, aircraft X called on my frequency at FL210. At this time, I had no prior knowledge of aircraft X (no flight plan on the sector, no handoff, no pointout). When the aircraft called, I answered his call and typed in the call sign into the computer to try and locate the aircraft. When I located the aircraft, it was 5 or 6 mi from the extreme northeastern corner of my airspace, and would enter my airspace in about 1 min. I was able to determine that the ZID controller had handed off the aircraft to an adjacent sector (ZTL-41) and I xferred communications to that sector. I then called the ZID controller to complete coordination, so that the aircraft would not enter my airspace without coordination, causing a deviation by the ZID controller. This error, or near error, was caused by a lack of attention by the ZID's controller who apparently thought the aircraft had been handed off to my sector (ZTL-41) but was actually handed off to ZTL-45.

Title: ZTL CTLR RESOLVES INCORRECT FREQ CHANGE, ALERTING THE XFERRING CTLR OF HIS ERROR.
Narrative: ACFT X WAS SSEBOUND FROM LEX TO ATL VIA DIRECT VXV MACEY2, AND LEVEL AT FL210. I WAS WORKING AT ZTL SECTOR 41 (SFC -- FL230, IN THE VICINITY OF CSV, CROSSVILLE, TN). AT APPROX XA50Z, ACFT X CALLED ON MY FREQ AT FL210. AT THIS TIME, I HAD NO PRIOR KNOWLEDGE OF ACFT X (NO FLT PLAN ON THE SECTOR, NO HDOF, NO POINTOUT). WHEN THE ACFT CALLED, I ANSWERED HIS CALL AND TYPED IN THE CALL SIGN INTO THE COMPUTER TO TRY AND LOCATE THE ACFT. WHEN I LOCATED THE ACFT, IT WAS 5 OR 6 MI FROM THE EXTREME NORTHEASTERN CORNER OF MY AIRSPACE, AND WOULD ENTER MY AIRSPACE IN ABOUT 1 MIN. I WAS ABLE TO DETERMINE THAT THE ZID CTLR HAD HANDED OFF THE ACFT TO AN ADJACENT SECTOR (ZTL-41) AND I XFERRED COMS TO THAT SECTOR. I THEN CALLED THE ZID CTLR TO COMPLETE COORD, SO THAT THE ACFT WOULD NOT ENTER MY AIRSPACE WITHOUT COORD, CAUSING A DEV BY THE ZID CTLR. THIS ERROR, OR NEAR ERROR, WAS CAUSED BY A LACK OF ATTN BY THE ZID'S CTLR WHO APPARENTLY THOUGHT THE ACFT HAD BEEN HANDED OFF TO MY SECTOR (ZTL-41) BUT WAS ACTUALLY HANDED OFF TO ZTL-45.
