-; Asterisk Call Detail Records (CDR) - Syslog Backend
-;
-
-; The cdr_syslog module writes CDRs using the facilities provided by syslog.
-;
-; Not only must you configure cdr_syslog from this file (cdr_syslog.conf) but
-; you will also need to make changes to your /etc/syslog.conf before CDRs will
-; be written to syslog.
-;
-; As an example, you can add the following to /etc/syslog.conf:
-;
-; local4.info /var/log/asterisk-cdr.log
-;
-; And then instruct syslogd to re-read the configuration file by sending it a
-; HUP signal. On Linux this can be done like this:
-;
-; kill -HUP `cat /var/run/syslogd.pid`
-;
-; Finally, you will need to uncomment the [cdr-simple] section below, and restart
-; Asterisk. When calls are placed, you should start seeing records appear in
-; /var/log/asterisk-cdr.log.
-
-[general]
-; Facility
-;
-; The 'facility' keyword specifies the syslog facility to use when writing out
-; CDRs.
-;
-; Accepted values: One of the following:
-; user, local0, local1, local2, local3, local4, local5, local6
-; and local7.
-;
-; Note: Depending on your platform, the following may also be
-; available:
-; auth, authpriv, cron, daemon, ftp, kern, lpr, mail,
-; news, syslog, and uucp.
-;
-; Default value: local4
-
-;facility=local0
-
-; Priority
-;
-; Use the 'priority' keyword to select which of the syslog priority levels to
-; use when logging CDRs.
-;
-; Accepted values: One of the following:
-; alert, crit, debug, emerg, err, info, notice, warning
-; Default value: info
-
-;priority=warn
-
-; Note: The settings for 'facility' and 'priority' in the [general] section
-; define the default values for all of the logging locations created
-; below in separate sections.
-
-;[cdr-master]
-;facility = local5
-;priority = debug
-
-; Template
-;
-; The 'template' value allows you to specify a custom format for messages
-; written to syslog. This is similar to how cdr_custom is configured.
-;
-; Allowed values: A diaplan style string.
-; Default value: None, this is required field.
-;
-; Note: Because of the way substitution is done, the only meaningful values
-; available when the record is logged are those available via the CDR()
-; dialplan function. All other channel variables will be unavailable.
-
-;template = "${CDR(clid)}","${CDR(src)}","${CDR(dst)}","${CDR(dcontext)}","${CDR(channel)}","${CDR(dstchannel)}","${CDR(lastapp)}","${CDR(lastdata)}","${CDR(start)}","${CDR(answer)}","${CDR(end)}","${CDR(duration)}","${CDR(billsec)}","${CDR(disposition)}","${CDR(amaflags)}","${CDR(accountcode)}","${CDR(uniqueid)}","${CDR(userfield)}"

-;[cdr-simple]
-
-; Since we don't specify a facility or priority for this logging location, the
-; records will use the defaults specified in the [general] section.
