  2. Call Accounting Options for SBCS • Call Detail Records sent to a Syslog Server • Call Detail Records sent to a Radius Server • Call Detail Records sent to an FTP Server

  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

  4. CDRs sent to a Radius Server UC500 Configuration service timestamps log datetime msec localtime ! aaa new-model aaa accounting connection h323 start-stop broadcast group radius aaa session-id common ! radius-server host <IP of RADIUS Server> radius-server vsa send accounting radius-server vsa send authentication • Pros: • More reliable accounting • Vendor Specific Attributes (VSA) • Customized records • Specific captures can be stored in flash (templates) • Multiple servers • Cons: • More configuration/customization • Requires RADIUS infrastructure (typically deployed on the WAN) • Important: • Make sure that clock settings are accurate, for proper time stamping. NTP is recommended. PSTN Internet RADIUS Server Syslog Server

  5. CDRs sent to a FTP Server UC500 Configuration service timestamps log datetime msec localtime ! gw-accounting aaa ! gw-accounting file primary ftp <FTP Server IP Address> username <username> password <password> secondary ifs flash:cdr maximum buffer-size 15 maximum retry-count 3 maximum fileclose-timer 300 maximum cdrflush-timer 245 • Pros: • Easy to Configure • Low Cost • Quick Deployment • Easy to interpret (CSV format) • Reliable transport (LAN/WAN) • CDR’s can be backed up to flash (make sure you have enough space) • Cons: • CPU intensive on busy systems (timers need to be tweaked) • Important: • Make sure that clock settings are accurate, for proper time stamping. NTP is recommended. PSTN/VoIP FTP Server
