49.1.1 Event Representation in Syslog Messages

The Syslog message events that the device sends are represented by unique
abbreviations. An example of an abbreviated event in a Syslog message indicating packet
loss (PL) is shown below:
Apr 4 12:00:12 172.30.1.14 PL:5

You can disable the inclusion of the message sequence number in
Syslog messages, by setting the 'CDR Session ID' parameter to
Disable (see Configuring CDR Reporting on page 634).
Ignore this number; it has been replaced by the Message Sequence
Number (described previously).
Automatically assigned (random), unique session identifier (session-
id / SID) number per call in the CDR of sent Syslog messages and
debug recording packets. This enables you to filter the information
(such as SIP, Syslog, and media) according to the SID.

Gateway application: A call session is considered either as a Tel-
to-IP leg or an IP-to-Tel leg, where each leg is assigned a unique
SID.

SBC application: A session is considered as both the outgoing
and incoming legs, where both legs share the same SID.
The benefit of this unique numbering is that it enables you to filter the
information (such as SIP, Syslog, and media) according to a specific
SID.
Note: Forked legs and alternative legs share the same SID.
Describes the message.
When the Network Time Protocol (NTP) is enabled, a timestamp
string [hour:minutes:seconds] is added to all Syslog messages.
