Keep-alive interval

 

This parameter specifies how often the GXP sends a blank UDP packet to the

 

 

 

 

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

 

 

 

 

 

 

 

 

 

 

 

 

Use NAT IP

 

NAT IP address used in SIP/SDP message. Default is blank.

 

 

 

 

 

 

 

 

 

 

 

 

STUN Server

 

IP address or Domain name of the STUN server. STUN resolution result will be

 

 

 

 

displayed in the STATUS page of the Web UI.

 

 

 

 

 

 

 

 

 

 

 

 

 

Firmware Upgrade and

 

Default method is HTTP. Firmware upgrade may take up to 10 minutes

 

 

Provisioning

 

depending on network environment. Do not interrupt the firmware upgrading

 

 

 

 

 

 

process.

 

 

 

 

 

 

 

 

 

 

 

 

Via TFTP Server

 

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

 

 

 

 

zero or not blank, the GXP will attempt to retrieve a new configuration file or new

 

 

 

 

code image from the specified TFTP server at boot time. It will make up to 3

 

 

 

 

attempts before 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 will be verified and then saved

 

 

 

 

into the Flash memory.

 

 

 

 

 

Note: Grandstream strongly recommends that the user upgrade firmware locally

 

 

 

 

in a LAN environment if using TFTP to upgrade. Please do NOT interrupt the

 

 

 

 

TFTP upgrade process (especially the power supply) as this will damage the

 

 

 

 

device.

 

 

 

 

 

 

 

 

 

 

 

 

Via HTTP Server

 

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

 

 

 

 

For example: http://provisioning.mycompany.com:6688/Grandstream/1.2.5.3

 

 

 

 

Here “:6688” is the specific TCP port that the HTTP server is using; omit if using

 

 

 

 

default port 80.

 

 

 

 

 

Note: If Auto Upgrade is set to No, GXP will only perform HTTP download once

 

 

 

 

at boot up.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Config Server Path

 

IP address or domain name of firmware server.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

XML Config File Password

 

The XML provisioning system allows Grandstream phones to perform

 

 

(For

 

configuration updates via XML configuration files. Users can set the XML config

 

 

GXP280/GXP/285/GXP1200

 

file password in the web UI of the phone.

 

 

 

Only)

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Firmware File

 

Default is blank. If configured, GXP will request the firmware file with the

 

 

Prefix/Postfix

 

prefix/postfix. This setting is useful for ITSPs. End user should keep it blank.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Config File

 

Default is blank. End user should keep it blank.

 

 

 

Prefix/Postfix

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Allow DHCP Option 43 and

 

Default is Yes. This allows the device to get provisioned automatically.

 

 

Option 66 to override

 

 

 

 

 

server

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Authenticate Conf File

 

 

 

 

 

Default is “No”. If set to “Yes”, configuration file would be authenticated before

 

 

 

 

acceptance. End user should use default setting.
