Layer 3 QoS

 

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

 

Value used for layer 2 VLAN tag. Default setting is blank.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

STUN Server

 

IP address or Domain name of the STUN server.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Keep-alive interval

 

This parameter specifies how often the HT–502 sends a blank UDP packet to the

 

 

 

 

SIP server in order to keep the “hole” on the NAT open. Default is 20 seconds.

 

 

 

 

Minimum value is 20 seconds.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Firmware Upgrade

 

Enables HT–502 to download firmware or configuration file through either the

 

 

and Provisioning

 

TFTP or HTTP server.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Via TFTP Server

 

This is the IP address of the configured TFTP server.

If selected and it is non-

 

 

 

 

zero or not blank, the HT–502 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: 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, ttp://provisioning.mycompany.com:6688/Grandstream/1.0.0.34

 

 

 

 

:6688” is the specific TCP port where the HTTP server is listening; it can be

 

 

 

 

omitted if using default port 80.

 

 

 

 

 

Note: If Auto Upgrade is set to No, HT–502 will only do HTTP download once at

 

 

 

 

boot up.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Firmware Server

 

IP address or domain name of firmware server.

 

 

 

Path

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Config Server Path

 

IP address or domain name of configuration server.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Firmware File Prefix

 

Default is blank.

If configured, HT–502 will request firmware file with the prefix.

 

 

 

 

This setting is useful for ITSPs. End user should keep it blank.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Firmware File

 

Default is blank. End user should keep it blank.

 

 

 

Postfix

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Config File Prefix

 

Default is blank. End user should keep it blank.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Config File Postfix

 

Default is blank. End user should keep it blank.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Automatic Upgrade

 

Choose “Yes” to enable automatic upgrade and provisioning. In “Check for new

 

 

 

 

firmware every” field, enter the number of days to enable HT-502 to check the

 

 

 

 

server for firmware upgrade or configuration in the defined period of days. When

 

 

 

 

set to No, HT-502 will only do upgrade once at boot up. “Always check for New

 

 

 

 

Firmware.” Check New Firmware only when F/W pre/suffix changes”
