48.1.1.2 Provisioning from TFTP Server using DHCP Option 66

Provisioning the device from a third-party TFTP server is suitable when the network in
which the device is deployed includes a provisioning TFTP server for all network
equipment, without the capability of distinguishing between AudioCodes and non-
AudioCodes devices.
Upon startup, the device checks for DHCP Option 66 in the DHCP response received from
the DHCP server. If Option 66 contains a valid IP address (or FQDN) of the TFTP
provisioning server, the device attempts to download through TFTP, a configuration file
whose filename contains the device's MAC address (e.g., 00908f0130aa.ini).
This method loads the configuration file to the device as a one-time action. The download
is repeated only if the device is manually restored to factory defaults (by pressing the
hardware reset button while the Ethernet cable is not connected) and DHCP is enabled
(see note below).
