I can't seem to get call detail records to be logged from my gatekeeper. I have the aaa command to get accounting go to my tacacs server. And in the gatekeeper section of my config, I have the accounting vsa command - I've also tried "accounting username h323". But the only records I've found in the tacacs logs from the gatekeeper were records of the changes I made to the config. Not call detail records. What am I missing?
