Administrator password. Only the administrator can configure the "Advanced Settings"

This field defines the layer 3 QoS parameter which can be the value used for IP
Precedence or Diff-Serv or MPLS. Default value is 48.
Layer 2 QoS settings. Default setting is blank. 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. Default is 20 seconds.
Use STUN keep-alive to detect WAN side network problems. If keep-alive request does
not 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 feat
ure is disabled.
Enables the HT503 to download firmware or configuration files through either TFTP or
HTTP servers. The default method is HTTP.
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
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.
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.
IP address or domain name of firmware server.
IP address or domain name of configuration server.
