ONFIGURATION THROUGH A CENTRAL SERVER
Grandstream HT-502 can be automatically configured from a central provisioning system.
When HT-502 boot up, it will send TFTP or HTTP request to download configuration file,
“cfg000b82xxxxxx”, where “000b82xxxxxx” is the LAN side MAC address of the HT-502
Download the configuration files via TFTP or HTTP from the central server. A service provider or an
enterprise with large deployment of HT-502 can easily manage the configuration and service provisioning
of individual devices remotely from a central server.
GAPS – GRANDSTREAM AUTOMATED PROVISIONING SYSTEM
Grandstream provides a licensed provisioning system called GAPS (Grandstream Automated Provisioning
System) that is used to support automated configuration of HT-502. GAPS uses enhanced (NAT friendly)
TFTP or HTTP (thus no NAT issues) and other communication protocols to communicate with each
individual HT-502 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
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 http://www.grandstream.com/configurationtool.html
