Configuration through a Central Server
Grandstream HT503 can be automatically configured from a central provisioning system.
When HT503 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
HT503. It will first request “cfg000b82xxxxxx” then “cfg000b82xxxxxx.xml”
A service provider or an enterprise with large deployment of Grandstream devices can easily manage the
configuration and service provisioning of individual devices remotely from a central server.
Grandstream has a central provisioning system called GAPS (Grandstream Automated Provisioning
System). GAPS supports automatic 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.
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/support/tools .
