SLS exports call-recording data in survivability mode. The Call Detail Record (CDR) log contains detailed information about each outgoing call that uses a trunk. This information can be stored in flash NVRAM or directed to an external server for later processing. It includes data for:
The Syslog information is stored in a memory file that is configured as a FIFO with a length of 50 KB. Once the last entry in the memory is full, the newest log event overwrites the oldest entry. This provides for a storage of 667 call records that may be saved during SLS operation. If you have a Syslog server on a PC connected to the local area network of the branch office, then these Syslog messages can be immediately transported from the Branch Gateway to the Syslog server. This enables the capture period to run for an extended period.
