Firmware 1.2.5.3 Last Updated: 03/2011
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
Provisioning
Default method is HTTP. Firmware upgrade may take up to 10 minutes
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 fi
le 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 (es
pecially 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.

file password in the web UI of the phone.
