CCM will not control the analog telephony of the FXO, which is where it sounds like you may be having the problems. This is in contrast to a PRI where CCM controls the signaling on the PRI.

i apllied no battery reversal,but its again the same pblm.

I think there may be any service parameter in CCM.

Please suggest

I can't think of anything else off the top of my head. You could put a TAC case in to pull the traces and debugs.
