Grandstream SIP Devices can be configured via Web Interface as well as via Configuration File
through TFTP or HTTP/HTTPS download. All Grandstream SIP devices support a proprietary
binary format configuration file. Product families such as GXP21xx/14xx/11xx, GXV31xx,
HT50x, HT70x, GXW40xx and DP71x accept configuration files in XML format in addition to
the legacy proprietary binary format. The XML provisioning implementation also allow generic
XML configuration file on top of the MAC based configuration file.
When Grandstream device boots up or reboots, it issues a request for a configuration file named
“cfgMAC”, where “MAC” is the MAC address of the device, for example “cfg000b820102ab”. The
configuration file name should be in lower case. The file “cfgMAC” is a proprietary binary format
configuration file that must be generated by Grandstream configuration tools. For devices that
support XML provisioning, they will also issue a request for a XML configuration file
“cfgMAC.xml”.
