The Grandstream HT503 can be automatically configured from a central provisioning system. 
 
When the HT503 boots up, it will send TFTP or HTTP request to download configuration file, 
“cfg000b82xxxxxx”, where “000b82xxxxxx” is the LAN MAC address of the HT503. 
 
The configuration files can be downloaded via TFTP or HTTP from the central server. A service provider 
or an enterprise with large deployment of HT503 can easily manage the configuration and service 
provisioning of individual devices remotely from a central server.  
 
Grandstream provides a licensed provisioning system called GAPS that can be used to support 
automated configuration of HT503. GAPS (Grandstream Automated Provisioning System) uses enhanced 
(NAT friendly) TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate 
with each individual HT503 for firmware upgrade, remote reboot, etc.  
 
Grandstream provide GAPS (Grandstream Automated Provisioning System) service to VoIP service 
providers.  It could be either simple redirection or with certain special provisioning settings. Initially upon 
booting 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 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
