Restoring and Backing up the Gateway Configuration

The Configuration File screen enables you to restore (load a new ini file to the gateway) or to
back up (make a copy of the VoIP gateway ini file and store it in a directory on your
computer) the current configuration the gateway is using.
Back up your configuration if you want to protect your VoIP gateway programming. The
backup ini file includes only those parameters that were modified and contain other than
default values.
Restore your configuration if the VoIP gateway has been replaced or has lost its
programming information, you can restore the VoIP gateway configuration from a previous
backup or from a newly created ini file. To restore the VoIP gateway configuration from a
previous backup you must have a backup of the VoIP gateway information stored on your
computer.
To restore or back up the ini file:
Open the 'Configuration File' screen (Advanced Configuration menu > Configuration
File); the 'Configuration File' screen is displayed.
