Narrative:
I was the captain of flight XXX bna to bhm. We were level at 11000 ft. ATC called company traffic at 2:30 O'clock position (7 or 8 mi?). I reported company in sight and we were issued a climb to 15000 ft and maintain visual separation with company. I suggested we expedite climb above his level which we did. We leveled at 15000 ft at that time almost 2000 ft above company. The company aircraft continued to climb on a converging course, until almost directly under us and 300 ft below when we received an RA to climb. We climbed to 15300 ft and received monitor vertical speed advisory. I reported the RA to center and was shortly issued climb to FL180. I later talked to company aircraft and was told he received RA also. He was also cleared to 15000 ft. I am still at a loss as to what happened.

Narrative: I WAS THE CAPT OF FLT XXX BNA TO BHM. WE WERE LEVEL AT 11000 FT. ATC CALLED COMPANY TFC AT 2:30 O'CLOCK POS (7 OR 8 MI?). I RPTED COMPANY IN SIGHT AND WE WERE ISSUED A CLB TO 15000 FT AND MAINTAIN VISUAL SEPARATION WITH COMPANY. I SUGGESTED WE EXPEDITE CLB ABOVE HIS LEVEL WHICH WE DID. WE LEVELED AT 15000 FT AT THAT TIME ALMOST 2000 FT ABOVE COMPANY. THE COMPANY ACFT CONTINUED TO CLB ON A CONVERGING COURSE, UNTIL ALMOST DIRECTLY UNDER US AND 300 FT BELOW WHEN WE RECEIVED AN RA TO CLB. WE CLBED TO 15300 FT AND RECEIVED MONITOR VERT SPD ADVISORY. I RPTED THE RA TO CTR AND WAS SHORTLY ISSUED CLB TO FL180. I LATER TALKED TO COMPANY ACFT AND WAS TOLD HE RECEIVED RA ALSO. HE WAS ALSO CLRED TO 15000 FT. I AM STILL AT A LOSS AS TO WHAT HAPPENED.
