XML Config File Password:

The GAC2500 XML config file can be encrypted using OpenSSL. When it's encrypted, the GAC2500

must supply the correct password in this field so it can decrypt XML configuration file after downloading

it. Then the configuration can be applied to the GAC2500. Please note this feature is supported on XML

config file instead of the binary config file. Therefore, it's recommended to use XML config file format

and encrypt it with this feature.

Validate Certificate Chain:

This configures whether to validate the server certificate when downloading the firmware/config file. If

set to "Yes", the phone will download the firmware/config file only from the legitimate server.

GAC2500 supports uploading CA certificate to validate the server certificate and this setting is under

GAC2500 web UI → System Settings → Security Settings.
