A service provider or an enterprise with a large deployment of HT–496 can easily manage the configuration and service provisioning of individual devices remotely from a central server. The format of the configuration file is as follows: “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the HT–496.

GAPSLITE - Grandstream Automated Provisioning System – supports the automated configuration of the HT–496. It is licensed-based software. GAPSLITE uses enhanced (NAT friendly) TFTP or HTTP and other communication protocols to communicate with each individual HT–496 for firmware upgrade, remote reboot, etc. The GAPSLITE software package also has a configuration tool to generate device configuration files.

GAPSLITE is the default for all Grandstream devices. Based on the unique MAC address, GAPSLITE provisions the devices with re-direction settings to point to a customer’s TFTP or HTTP server for further provisioning. This could be simple re-direction or with special provisioning settings.

The GAPSLITE configuration tool is free with purchases over 512 units. Less than 512 units, the license fee is $999.95. The tool and configuration templates is available on http://www.grandstream.com/y- configurationtool.htm
