Saving the Configuration Changes 
Click the “Update” button in the Configuration page to save the changes to the HT502 configuration. The 
following screen confirms that the changes are saved.  Reboot or power cycle the HT502 to make the

Rebooting the HT502 from Remote 
Press the “Reboot” button at the bottom of the configuration menu to reboot the ATA remotely. The web 
browser will then display a message window to confirm that reboot is underway. Wait 30 seconds to log in 
again. 
 
 
Configuration through a Central Server 
Grandstream HT502 can be automatically configured from a central provisioning system. 
 
When HT502 boot up, it will send TFTP or HTTP/HTTPS request to download configuration file,  
“cfg000b82xxxxxx” or “cfg00082xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the 
HT502. It will first request “cfg000b82xxxxxx” then “cfg000b82xxxxxx.xml” 
 
The configuration file can be downloaded via TFTP or HTTP/HTTPS from the central server. A service 
provider or an enterprise with large deployment of HT502 can easily manage the configuration and service 
provisioning of individual devices remotely from a central server.  
 
Grandstream has a provisioning system called GAPS (Grandstream Automated Provisioning System) that 
is used to support automated configuration of Grandstream devices.  GAPS uses enhanced (NAT friendly) 
TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each 
individual Grandstream device for firmware upgrade, remote reboot, etc.  
 
Grandstream provides GAPS service to VoIP service providers.  Use GAPS for either simple redirection or 
with certain special provisioning settings.  At boot-up, Grandstream devices by default point to 
Grandstream provisioning server GAPS, based on the unique MAC address of each device, GAPS 
provision the devices with redirection settings so that they will be redirected to customer’s TFTP or 
HTTP/HTTPS server for further provisioning.  Grandstream also provide GAPSLITE software package 
which contains our NAT friendly TFTP server and a configuration tool to facilitate the task of generating 
device configuration files.   
  
The GAPSLITE configuration tool is now free to end users. The tool and configuration template are 
available for download from
