53.2.1.2 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:
Numerical Value
16 (default)
17
18
19
20
21
22
23
Syslog messages begin with a less-than ("<") character, followed by a number, which is
followed by a greater-than (">") character. This is optionally followed by a single ASCII
space. The number is known as the Priority and represents both the Facility level and the
Severity level. A Syslog message with Facility level 16 is shown below:
Facility: LOCAL0 - reserved for local use (16)

53.2.1.3 Syslog Fields for Answering Machine Detection (AMD)

The Syslog message can include information relating to the Answering Machine Detection
(AMD) feature. AMD is used to detect whether a human (including a fax machine), an
answering machine, silence, or answering machine beeps have answered the call on the
remote side.

AMDSignal – the field can acquire one of the following values:
•
voice (V)
•
answer machine (A)
•
silence (S)
•
unknown (U)
