Provisioning is a process where all the necessary primary settings are applied to a device to prepare it for first-time use. Grandstream’s SIP devices can be configured through the web interface as well as the configuration file through TFTP or HTTP/HTTPS download.   All Grandstream SIP devices support a proprietary binary format configuration file. New product families such as GXP21xx/14xx/11xx, GXV31xx, HT50x and GXW40xx accept configuration files in XML format in addition to the legacy proprietary binary format.
