Grandstream Networks GXV-3000 User Manual page 30

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 GXV-3000s are behind the same full cone NAT.
Default is No. (This parameter should be set to NO before Direct IP Call will work)
Keep-alive This parameter specifies how often the GXV-3000 sends a blank UDP packet to the SIP server in
interval
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-
This radio button will enable GXV-3000 to download firmware or configuration file through either
grade and Provi- HTTP or TFTP (local preferred) server. This is mutual exclusive choice.
sioning
Via TFTP Server This is the IP address of the configured TFTP server. If selected and it is non-zero or not blank, the
GXV-3000 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 proc-
ess 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 (espe-
cially 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/1.1.3.50
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, GXV-3000 will only perform HTTP download once at boot up.
Firmware This is the server path for Firmware server. It can be different with the Configuration server which

Allow DHCP Default is Yes.
Option 66 to If DHCP option 66 turned ON in LAN, the TFTP server can be redirected. Please be very careful
override server to this as the redirection could brick the phone if happed during firmware upgrade.
Automatic This function is used by ITSP. End user should NOT touch these parameters.
Upgrade
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-
