5.3 Configuration through Central Provisioning Server
Grandstream GXP-2000 can be automatically configured from a central provisioning
system.
When GXP-2000 boots up, it will send TFTP or HTTP request to download configuration
files, there are two configuration files, one is “cfg.txt” and the other is
“cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the GXP-2000.
The configuration files can be downloaded via TFTP or HTTP from the central server. A
service provider or an enterprise with large deployment of GXP-2000 can easily manage
the configuration and service provisioning of individual devices remotely from a central
server.
Grandstream provides a licensed provisioning system called GAPS that can be used to
support automated configuration of GXP-2000. GAPS (Grandstream Automated
Provisioning System) uses enhanced (NAT friendly) TFTP or HTTP (thus no NAT
issues) and other communication protocols to communicate with each individual GXP-
2000 for firmware upgrade, remote reboot, etc.
Grandstream provide GAPS (Grandstream Automated Provisioning System) service to
VoIP service providers. It could be either simple redirection or with certain special
provisioning settings. Initially upon booting 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.
