Grandstream phones can be configured individually by assigning them an IP address and then browsing to their configuration web-pages. However, any sizable deployment will quickly outgrow that approach. Instead, system administrators will likely opt to have the phones download a tailored configuration based on the phones' MAC addresses. These configuration files can be generated using Grandstream's template and configuration tool. However, assuming that each phone is in some way unique, this approach still requires that the configuration tool be run once for each phone; still labor intensive. Thanks to a description of the configuration file's layout on the VoIP Info website, PBnJ Solutions was able to build a small Perl utility to generate compatible configuration files.

Both for validation as well as compatibility reasons, the utility, dubbed gscfg, uses the same profile descriptions as Grandstream's GUI tool.
