Narrative:
ATC gave us a turn to 140 degree heading. I read back 140 degree heading. In the turn, the copilot noticed traffic 2300 ft below and climbing. When I called to question ATC, we received a climb RA. I notified ATC we were responding to a climb RA, at which time he turned us. After returning to 7000 ft, I asked ATC if we had created the conflict. He said no. I asked 'should I call him after we land?' he said no. Later we heard air carrier Y on the frequency. The controller might have meant to vector air carrier Y, however he said air carrier X.

Title: B737 FLC CLBED IN RESPONSE TO A TCASII RA AND WERE SUBSEQUENTLY TURNED OFF COURSE TO BE SEPARATED FROM OTHER TFC CLBING. SIMILAR ACFT CALL SIGNS WAS THE PROB.
Narrative: ATC GAVE US A TURN TO 140 DEG HDG. I READ BACK 140 DEG HDG. IN THE TURN, THE COPLT NOTICED TFC 2300 FT BELOW AND CLBING. WHEN I CALLED TO QUESTION ATC, WE RECEIVED A CLB RA. I NOTIFIED ATC WE WERE RESPONDING TO A CLB RA, AT WHICH TIME HE TURNED US. AFTER RETURNING TO 7000 FT, I ASKED ATC IF WE HAD CREATED THE CONFLICT. HE SAID NO. I ASKED 'SHOULD I CALL HIM AFTER WE LAND?' HE SAID NO. LATER WE HEARD ACR Y ON THE FREQ. THE CTLR MIGHT HAVE MEANT TO VECTOR ACR Y, HOWEVER HE SAID ACR X.
