Note:
The message severity is Informational but media statistics messages are always published, irrespective of the
severity filters.
Call Detail Records (CDRs)
The system can capture CDRs if you enable the service (which is off by default), and can publish them as syslog
messages if you are using remote logging.

If you select Service only the system keeps the CDRs for 7 days, and these CDRs can only be read via the REST API to

Notes:

CDR reporting is best effort and the CDRs cannot be relied upon for accurate billing purposes.

The local 7 days worth of CDR data is written to disk. It is preserved over a system restart/reboot, and is

Publishing Logs to Remote Syslog Servers
Syslog is a convenient way to aggregate log messages from multiple systems to a single location. This is particularly
recommended for peers in a cluster.
recommended for peers in a cluster.

You can configure the VCS to publish log messages to up to 4 remote syslog servers.

The syslog servers must support one of the following standard protocols:

Configuring remote syslog servers
1.
Go to Maintenance > Logging, and enter the IP addresses or Fully Qualified Domain Names (FQDNs) of the
Remote syslog servers to which this system will send log messages.
Remote syslog servers to which this system will send log messages.
2.
For each server address, specify the syslog protocol in the Mode field.
If you select Custom, you can specify the Transport, Port, and Format.
If you select Custom, you can specify the Transport, Port, and Format.
3.
For each server, use the Log level control to select how much detail to send.
The VCS sends messages of the selected severity and all of the more severe messages.

4.
Click Save.
Which Mode should I use?
The Mode option of the VCS's syslog feature configures several parameters of the outgoing syslog messages. The
following table should help you select the mode that best matches your logging server(s) and network configuration.
Custom allows you the most control over the transport, port, and message format used, and you must use Custom if
you want revocation checking for the syslog server certificate.
