asterisk users - Jan 2005 - the correct way to stop a CDR?

Hey gang,
 Currently I have this dialplan:

 exten => _9.,1,Dial(blah/blah)

 exten => h,1,ResetCDR(w)
 exten => h,2,NoCDR()
 exten => h,3,DeadAGI(rate_call.php)

The AGI script takes the completed call, determines all that NPNAXX crap,
finds the cost and then updates the CDR with the cost.

Problem is, I keep getting these messages:

Jan  4 13:25:36 WARNING[13689]: cdr.c:114 ast_cdr_free: CDR on channel
'SIP/3091-c362' not posted
Jan  4 13:25:36 WARNING[13689]: cdr.c:116 ast_cdr_free: CDR on channel
'SIP/3091-c362' lacks end

These messages are being generated by NoCDR. Is there a better way to
stop/post a CDR?

I am considering adding a flag to ResetCDR(x) so that if you pass this flag,
it stops the CDR, posts it, then frees it.

Any thoughts? Ideas on a better way to rate the call?

Thanks,
Matthew
