Mediant 800B Gateway & E-SBC
Message Item Description
number in Syslog messages, by setting the 'CDR Syslog
Sequence Number' parameter to Disable (see 'Configuring
Syslog' on page
1018).
Log Number
(lgr)(number)
Ignore this number; it has been replaced by the Message
Sequence Number (described previously).
Session ID (SID)
Unique SIP call session and device identifier. The device
identifier facilitates debugging by clearly identifying the
specific device that sent the log message, especially useful in
deployments consisting of multiple devices. In addition, the
benefit of unique numbering is that it enables you to filter the
information (such as SIP, Syslog, and media) according to
device or session ID.
The syntax of the session and device identifiers are as
follows:
[SID=<last 6 characters of device's MAC address>:<number
of times device has reset>:<unique SID counter indicating the
call session; increments consecutively for each new session;
resets to 1 after a device reset>]
For example:
14:32:52.028: 10.33.8.70: NOTICE: [S=9369]
[SID=2ed1c8:96:5] (lgr_psbrdex)(274) recv
<-- OFF_HOOK Ch:4
Where:
 2ed1c8 is the device's MAC address.
 96 is the number of times the device has reset.
 5 is a unique SID session number (in other words, this is
the fifth call session since the last device reset).

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 session number.

SBC application: A session includes both the outgoing
and incoming legs, where both legs share the same
session number.

Forked legs and alternative legs share the same
session number.
Board ID (BID)
Unique non-SIP session related (e.g., device reset or a Trunk
alarm) and device identifier. The device identifier facilitates
debugging by clearly identifying the specific device that sent
the log message, especially useful in deployments consisting
of multiple devices. In addition, the benefit of unique
numbering is that it enables you to filter the information
according to device.
The syntax of the BID is as follows:
[BID=<last 6 characters in MAC>:<number of times device
has reset>]
For example:
14:32:52.062: 10.33.8.70: WARNING: [S=9399]
[BID=2ed1c8:96] invalid Physical index
Where:
 2ed1c8 is the device's MAC address.
 96 is the number of times the device has reset.
