[. . . ] User can change the administrator password here. The password is case sensitive and the maximum length is 25 characters. TABLE 9: HT503 ADVANCED SETTINGS PAGE DEFINITIONS Admin Password Administrator password. Only the administrator can configure the "Advanced Settings" page. Password field is purposely blanked for security reason after clicking update and saved. The maximum password length is 25 characters. This field defines the layer 3 QoS parameter which can be the value used for IP Precedence or Diff-Serv or MPLS. VLAN supported equipment is required when configuring these settings. IP address or Domain name of the STUN server. This parameter specifies how often the HT503 sends a blank UDP packet to the SIP server in order to keep the NAT "pin hole" open. Enables the HT503 to download firmware or configuration files through either TFTP or HTTP servers. This is the IP address of the configured TFTP server. If this is configured, the HT503 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 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: Firmware upgrades may take up to 10 minutes depending on your network environment. On a LAN it usually takes about 2 minutes. 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, http://provisioning. mycompany. com:6688/Grandstream/1. 0. 0. 6 ":6688" is the specific TCP port where the HTTP server is listening; Omit if using default port 80. Note: If Auto Upgrade is set to No, F/W will download at boot time. [. . . ] For a detailed parameter list, please refer to the corresponding firmware release configuration template. When Grandstream Device boots up or reboots, it will issue request for configuration file named "cfgxxxxxxxxxxxx", where "xxxxxxxxxxxx" is the LAN MAC address of the device, i. e. , "cfg000b820102ab". The configuration file name should be in lower cases. FIRMWARE AND CONFIGURATION FILE PREFIX AND POSTFIX Firmware Prefix and Postfix allows device to download the firmware name with the matching Prefix and Postfix. This makes it possible to store ALL of the firmware with different version in one single directory. [. . . ]
