
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)

50.2.1.3 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)

AMDDecisionProbability – probability (in %) success that correctly detects answering
type
Below is an example of such a Syslog message with AMD information:
CallMachine:EVENT_DETECTED_EV - AMDSignal = <type – V/A/S/U>,
AMDDecisionProbability = <percentage> %
If there is no AMD detection, the AMDSignal field is shown empty (i.e. AMDSignal = ).
For more information on the AMD feature, see ''Answering Machine Detection (AMD)'' on
page 191.

50.2.1.4 SNMP Alarms in Syslog Messages

SNMP alerts are sent to the Syslog server using the following formats:

Raised Alarms: RAISE-ALARM: <Alarm Name>; Textual Description: <Textual
Description>; Severity <Alarm Severity>; Source <Alarm Source>; Unique ID: <Alarm
Unique ID >.
