TABLE 9: ADVANCED CONFIGURATION PAGE DEFINITIONS

Admin

Password

Administrator password. Only the administrator can configure the “Advanced Settings”

page. Password field is purposely left blank for security reasons after clicking update

and saved. The maximum password length is 25 characters.

Layer 3 QoS

This field defines the layer 3 QoS parameter which can be the value used for IP

Precedence or Diff-Serv or MPLS. Default value is 48.

Layer 2 QoS

Value used for layer 2 VLAN tag. Default setting is blank.

STUN Server

IP address or Domain name of the STUN server.

Keep-alive

interval

This parameter specifies how often the GXW–400x sends a blank UDP packet to the

SIP server to keep the “hole” on the NAT open. Default is 20 seconds.

Firmware

Upgrade &

Provisioning

Enables GXW–400x to download firmware or configuration file through either the TFTP

or HTTP server.

Via TFTP Server

This is the IP address of the configured TFTP server. If selected and it is non-zero or

not blank, the GXW–400x retrieves the new configuration file or new code image from

the specified TFTP server at boot time. After 5 attempts, the system will timeout and

then it will start the boot process using the existing code image in the Flash memory. If

a TFTP server is configured and a new code image is retrieved, the new downloaded

image is saved into the Flash memory.

Note: Please do NOT interrupt the TFTP upgrade process (especially the power supply)

as this will damage the device. Depending on the network environment this process

can take up to 15 or 20 minutes.

Via HTTP Server

The URL for the HTTP server used for firmware upgrade and configuration via HTTP.

For example, ttp://provisioning.mycompany.com:6688/Grandstream/1.0.0.36

“:6688” is the specific TCP port where the HTTP server is listening; it can be omitted if

using default port 80.

Note: If Auto Upgrade is set to No, GXW–400x will only do HTTP download once at

boot up.

Automatic

Upgrade

Choose “Yes” to enable automatic upgrade and provisioning. In “Check for new

firmware every” field, enter the number of days to enable GXW–400x to check the

server for firmware upgrade or configuration in the defined period of days. When set to

No, GXW–400x will only do upgrade once at boot up. “Always check for New

Firmware.” Check New Firmware only when F/W pre/suffix changes”

Authenticate

Conf File

If set to Yes, config file is authenticated before acceptance. This protects the

configuration from an unauthorized change.

Firmware Key

For firmware encryption. It should be 32 digit in Hexadecimal Representation. End

user should keep it blank.

Lock Keypad

Update

If set to “Yes”, the configuration update via keypad is disabled.

NTP server

URI or IP address of the NTP (Network Time Protocol) server. Used by the phone to

synchronize the date and time.
