If you enable console messages, you can customize the types of
messages to be included/excluded in log reports by clicking on the
“Filters” button and using the Console Messages Filter Settings
screen (see subsequent page). If you use the logging function, select
the logging option that applies to your VoIP system design. If you
intend to use a SysLog Server program for logging, click in that
Enable check box. The common SysLog logical port number is 514. If
you intend to use the MultiVOIP web browser GUI for configuration
and control of MultiVOIP units, be aware that the web browser GUI
does not support logs directly. However, when the web browser GUI
is used, log files can still be sent to the voip administrator via email
(which requires activating the SMTP logging option in this screen).
