Firmware 1.2.3.7
Updated: 12/2010
Use Random Port This parameter, when set to “Yes”, will force random generation of both the local SIP and RTP
ports. This is usually necessary when multiple GXV300xs are behind the same full cone NAT. De-
fault is No. (This parameter should be set to NO when using Direct -IP Calls)
Keep-alive
interval
This parameter specifies how often the GXV300x sends a blank UDP packet to the SIP server in
order to keep the “pin hole” on the NAT router to open. Default is 20 seconds.
Use NAT IP
NAT IP address used in SIP/SDP message. Default is blank. Use ONLY if ITSP requires.
STUN Server
IP address or Domain name of the STUN server. STUN resolution result will display in the STA-
TUS page of the Web UI. Only non-symmetric NAT routers work with STUN.
Firmware Up-
grade and Provi-
sioning
This radio button will enable GXV300x to download firmware or configuration file through either
HTTP or TFTP (local preferred) server. This is mutual exclusive choice.
Via TFTP Server
This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank, the
GXV300x will attempt to retrieve a new configuration file or new firmware 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.
Note: Grandstream strongly recommends that the user upgrade firmware locally in a LAN envi-
ronment if using TFTP to upgrade. Please do NOT interrupt the TFTP upgrade process (especial-
ly the power supply) as this might damage the device.
Via HTTP Server
The HTTP server URL used for firmware upgrade and configuration. For example,
http://provisioning.mycompany.com:6688/Grandstream/1.2.2.5
Here “:6688” is the specific TCP
port that the HTTP server is using; it can be omitted if using default port 80. Please do not interrupt
power when doing firmware upgrade.
Note: If Auto Upgrade is set to No, GXV300x will only perform HTTP download once at boot up.
Firmware
Server Path
This is the server path for Firmware server. It can be different with the Configuration server which
used for provisioning
Config
Server Path
This is the server path for provisioning, it can be different with firmware server.
Firmware File
Prefix/Postfix
For ITSP to lock up firmware. If configured, only firmware matched with the encrypted Prefix
and/or Postfix will get download and flashed into the phone.
Config File
Prefix/Postfix
For ITSP to lock up configuration. If configured, only configuration file matched with the encrypted
Prefix and/or Postfix will get download and flashed into the phone.
Allow DHCP
Option 66 to
override server
Default is Yes.
If DHCP option 66 turned ON in LAN, the TFTP server can be redirected. Please be very careful
to this as the redirection could brick the phone if happed during firmware upgrade.
Automatic
Upgrade
This function is used by ITSP. End user should NOT touch these parameters.
Default is No. Choose “Yes” to enable automatic HTTP upgrade and provisioning.
In “Check for upgrade every” field, enter the number of minutes to check the HTTP server for firm-
ware upgrade or configuration changes. When set to “No”, the phone will only perform HTTP up-
grade and configuration check once at boot up.
Some other selections can be used to fine-tune this process, it is self-explainable.
