Cisco devices such as Call Manager Express generate a number of syslog event types. These logs include system interface up and down events and h.323 call logging. A Cisco Voice Gateway with PRI lines,will generate an %ISDN-6-CONNECT event when a call connects and an %ISDN-6-DISCONNECT when the call disconnects.
To generate proper call detail records and to generate billing records, which have numbers for both peers, full h.323 connection call accounting needs to be activated. The records from this log type generate a %VOIPAAA-5-VOIP_CALL_HISTORY syslog entry.
Resource Software International Ltd. (RSI) offers call accounting and communication management software for SMB to large enterprise environments with Cisco Call Manager or any Cisco device with an active syslog.
