Chapter 4—Configuring your VOIP
Multi-Tech Systems, Inc. 53
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. 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 interface for configuration and control of MultiVOIP units, be aware that the
web browser interface does not support logs directly. However, when the web browser interface is used, log
files can still be sent to the VOIP administrator via email (which requires using the SMTP logging option).
