Narrative:

We took off on runway 18L with a clearance to 10000 ft on the ceola 3 departure. Upon initial check-in with departure on 126.47; the controller deleted our speed restr at larrn. Near larrn waypoint we read back a climb clearance to 17000 ft. During our climbing turn wbound; through about 9000 ft; the controller gave us an advisory for traffic 10-11 O'clock position descending to 12000 ft. Now passing 10000 ft; I thought it would be best to climb rapidly through 12000 ft and remained at 250 KTS. About the time I realized the traffic would cross our flight path and altitude; we received a 'maintain vertical speed' climb RA. We accomplished the RA and it went to a 'monitor vertical speed' as the traffic passed by left to right below us by approximately 600 ft; 2-3 mi ahead. We reported the RA several times before the controller acknowledged and issued us a frequency change. I then asked him as to the conflict. He said we had acknowledged a radio call for a similar sounding flight that it was his fault for not catching it. Supplemental information from acn 691432: nighttime VMC.

ABOUT THE TIME I REALIZED THE TFC WOULD CROSS OUR FLT PATH AND ALT; WE RECEIVED A 'MAINTAIN VERT SPD' CLB RA. WE ACCOMPLISHED THE RA AND IT WENT TO A 'MONITOR VERT SPD' AS THE TFC PASSED BY L TO R BELOW US BY APPROX 600 FT; 2-3 MI AHEAD. WE RPTED THE RA SEVERAL TIMES BEFORE THE CTLR ACKNOWLEDGED AND ISSUED US A FREQ CHANGE. I THEN ASKED HIM AS TO THE CONFLICT. HE SAID WE HAD ACKNOWLEDGED A RADIO CALL FOR A SIMILAR SOUNDING FLT THAT IT WAS HIS FAULT FOR NOT CATCHING IT. SUPPLEMENTAL INFO FROM ACN 691432: NIGHTTIME VMC.
