  3. CDRs sent to a Syslog Server UC500 Configuration service timestamps log datetime msec localtime ! aaa new-model aaa authentication login default none aaa accounting connection h323 start-stop radius gw-accounting syslog ! logging <LAN IP Address of the Syslog Server> • Pros: • Easy to Configure • Low Cost • Quick Deployment • Easy to interpret (CSV format) • Cons: • Syslog works over UDP • LAN deployment only • No CDR backup • Important: • Make sure that clock settings are accurate, for proper time stamping. NTP is recommended. PSTN/VoIP Syslog Server
