To login to the Advanced Setting and FXS port configuration pages, administrator password is required. 
The default administrator password is “admin”. User can change the administrator password here. The 
password is case sensitive and the maximum length is 25 characters.  

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. 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.  

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/1.0.0.6 
“: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. 

IP address or domain name of firmware server. 

IP address or domain name of configuration server. 

Default is blank. If configured, HT503 will request the firmware file with the prefix.  This 
setting is useful for ITSPs.  End user should keep it blank.  

Default is blank. End users should keep it blank. 

Default is blank. End users should keep it blank. 

Default is blank. End users should keep it blank. 

Choose “Yes” to enable automatic upgrades and provisioning.  In “check for new 
firmware every” field, enter the number of days to set the frequency in which the HT503 
will check the server for firmware or configuration upgrades.  When set to “No” the 
HT503 will only upgrade at boot time.   You can also have the HT503 check for updates 
only when the firmware file prefix/suffix changes. The Default is “Yes”.  

This protects the configuration from an unauthorized change.  If set to “Yes, the 
configuration file is authenticated before acceptance. 

Key for firmware encryption. (32 digits in hexadecimal format. End users should keep it 
blank.  

The user specified SSL certificate used for SIP over TLS in X.509 format. 

The user specified SSL private key used for SIP over TLS in X.509 format. 

User specified password to protect the private key above.
