Narrative:
Our pre departure clearance was texoma 7 departure, mcalester transition which instructed us to fly heading 174 degrees and climb to 10000 ft. Prior to entering runway 18L we were given a new departure frequency. We were cleared for takeoff and to fly a heading of 185 degrees. After contacting departure control and being radar identified, the controller told us to fly heading 330 degrees and climb to 17000 ft. We readback the clearance and no other aircraft responded. Passing 6000 ft and a heading of 270 degrees the controller stated that we had accepted another aircraft's clearance and to immediately turn and fly runway heading. We turned and confirmed that our altitude clearance was 1000 ft. The controller then told air carrier Y to turn immediately to 330 degrees and climb to 17000. Again, we heard no response indicating to us that he was talking on both departure frequencys. The flight was routine after that.

Title: HDG TRACK DEV WHEN A DEP B727 ACCEPTS A CLRNC MEANT FOR ANOTHER AIRLINE COMPANY FLT SW OF DEV, TX.
Narrative: OUR PDC WAS TEXOMA 7 DEP, MCALESTER TRANSITION WHICH INSTRUCTED US TO FLY HDG 174 DEGS AND CLB TO 10000 FT. PRIOR TO ENTERING RWY 18L WE WERE GIVEN A NEW DEP FREQ. WE WERE CLRED FOR TKOF AND TO FLY A HDG OF 185 DEGS. AFTER CONTACTING DEP CTL AND BEING RADAR IDENTIFIED, THE CTLR TOLD US TO FLY HDG 330 DEGS AND CLB TO 17000 FT. WE READBACK THE CLRNC AND NO OTHER ACFT RESPONDED. PASSING 6000 FT AND A HDG OF 270 DEGS THE CTLR STATED THAT WE HAD ACCEPTED ANOTHER ACFT'S CLRNC AND TO IMMEDIATELY TURN AND FLY RWY HDG. WE TURNED AND CONFIRMED THAT OUR ALT CLRNC WAS 1000 FT. THE CTLR THEN TOLD ACR Y TO TURN IMMEDIATELY TO 330 DEGS AND CLB TO 17000. AGAIN, WE HEARD NO RESPONSE INDICATING TO US THAT HE WAS TALKING ON BOTH DEP FREQS. THE FLT WAS ROUTINE AFTER THAT.
