60.2.1.2  Identifying AudioCodes Syslog Messages using Facility Levels 
The device’s Syslog messages can easily be identified and distinguished from Syslog 
messages from other equipment, by setting its Facility level. The Facility levels of the 
device's Syslog messages are numerically coded with decimal values. Facility level may 
use any of the "local use" facilities (0 through 7), according to RFC 3164. Implementing 
Facility levels is useful, for example, if you collect the device’s as well as other equipments’ 
Syslog messages on the same server. Therefore, in addition to filtering Syslog messages 
by IP address, you can filter messages by Facility level. 
  To configure the Facility level: 
  Configure the SyslogFacility ini file parameter to one of the following options: 
Table  60-5: Syslog Facility Levels 
Numerical Value  Facility Level 
16 (default) 
local use 0  (local0)
