CONFIGURATION THROUGH A CENTRAL SERVER

Grandstream GXW40XX can be automatically configured from a central provisioning system.

When GXW40XX boots up, it will send TFTP or HTTP request to download configuration file, “cfg000b82xxxxxx” or “cfg000b82xxxxxx.xml”, where “000b82xxxxxx” is the LAN MAC address of the GXW40XX. 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 .
