Table 9: Advanced Settings - Grandstream Networks HT503 User Manual

Advanced User configuration includes not only the end user configuration, but also advanced
configurations such as: SIP configuration, Codec selection, NAT Traversal Setting and other
miscellaneous configuration.
Administrator password. Only the administrator can configure the "Advanced Settings" page.
Admin Password

maximum password length is 25 characters.
Layer 3 QoS This field defines the layer 3 QoS parameter which can be the value used for IP Precedence

Layer 2 QoS Layer 2 QoS settings. Default setting is blank. VLAN supported equipment is required when
configuring these settings.
STUN Server IP address or Domain name of the STUN server.
Keep-alive interval 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. Default is 20 seconds.
Use STUN to detect Use STUN keep-alive to detect WAN side network problems. If keep-alive request does not
network activity yield any response for configured number of times, the device will restart the TCP/IP
stack. If the STUN server does not respond when the device boots up, the feature is
disabled.
Firmware Upgrade
Enables the HT503 to download firmware or configuration files through either TFTP or HTTP
and Provisioning
servers. The default method is HTTP.
Via TFTP
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 The URL for the HTTP server used for firmware upgrade and configuration via HTTP.
For example, http://provisioning.mycompany.com:6688/Grandstream/1.0.6.8
":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.
Via HTTPS The URL of the HTTP server used for firmware upgrade and configuration via a secure HTTP
connection.
For example, https://provisioning.mycompany.com
Note: the HTTPS default port is 443.
Firmware Server IP address or domain name of firmware server.
