I setup syslog CDR accounting on a CME:
router(config)#service timestamps log datetime msec localtime
In the Cisco "CDR Accounting for Cisco IOS Voice Gateways" guide it is specified, that Fields 0 to 22 are included in the compact version of the CDR.
This includes for example the h323-conf-id, username, clid, dnis
The router send not all fields. I receive on the syslog server and in the console only the following fields:
Nov 6 18:15:30 AST: %VOIPAAA-5-VOIP_CALL_HISTORY: CallLegType 1, ConnectionId 3597CCC1AB8711DD8919001C58DF35A0, SetupTime 18:15:25.320 AST Thu Nov 6 2008, PeerAddress 410, PeerSubAddress , DisconnectCause 10 , DisconnectText normal call clearing (16), ConnectTime 18:15:30.910 AST Thu Nov 6 2008, DisconnectTime 18:15:30.910 AST Thu Nov 6 2008, CallOrigin 1, ChargedUnits 0, InfoType 2, TransmitPackets 0, TransmitBytes 0, ReceivePackets 0, ReceiveBytes 0
I miss h323-conf-id, username, clid, dnis for a better call leg correlation and analysis of the calls.
