DHCPEnable = 1
2. Enable the device to include DHCP Option 67 in DHCP Option 55 (Parameter Request List)
when requesting HTTP provisioning parameters from a DHCP server, using the following ini
file parameter:
DHCPRequestTFTPParams = 1

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).
