Narrative:
We received a resolution advisory at 30500' in climb. First officer at controls disconnected autoplt reduced power, and descended to approximately 29500'. I contacted jax center and advised them of a 'resolution advisory' on our TCAS system, and asked her if we had any conflicting traffic. She said nearest traffic was 12 mi away. I said we would reestablish climb and write up our onboard TCAS system. A few mins later she said we needed to advise center of deviations. I said we did. She did not understand that we deviate when we get an RA and I advised her as soon as possible.

Title: ACR MLG ALT DEVIATION EXCURSION FROM CLRNC ALT IN RESPONSE TO TCAS II RA.
Narrative: WE RECEIVED A RESOLUTION ADVISORY AT 30500' IN CLB. F/O AT CTLS DISCONNECTED AUTOPLT REDUCED PWR, AND DSNDED TO APPROX 29500'. I CONTACTED JAX CTR AND ADVISED THEM OF A 'RESOLUTION ADVISORY' ON OUR TCAS SYS, AND ASKED HER IF WE HAD ANY CONFLICTING TFC. SHE SAID NEAREST TFC WAS 12 MI AWAY. I SAID WE WOULD REESTABLISH CLB AND WRITE UP OUR ONBOARD TCAS SYS. A FEW MINS LATER SHE SAID WE NEEDED TO ADVISE CTR OF DEVS. I SAID WE DID. SHE DID NOT UNDERSTAND THAT WE DEVIATE WHEN WE GET AN RA AND I ADVISED HER AS SOON AS POSSIBLE.
