User's Manual 5. Automatic Configuration Options
Version 6.6 41 MediaPack Series
5.5 Option E - Configuration using FTP or NFS
Some networks block access to HTTP(S). The Automatic Update facility provides limited
support for FTP/FTPS connectivity, however it should be noted that periodic polling for
updates is not possible (since these protocols do not support conditional fetching, i.e.
update the file only if it is changed on the server).
The difference between this option and options C and D is simply the protocol in the URL -
ftp instead of http.
NFS v2/v3 is supported as well, see the user documentation for additional configuration
required to enable NFS.
Note that FTP is NAT-safe, while NFS is not.
5.6 Option F - TFTP Configuration using DHCP
Option 66
This option is suitable for cases where the end customer network contains a provisioning
TFTP server for all network equipment, without the possibility of distinction between
AudioCodes and non-AudioCodes devices.
Upon startup, the MP-1xx will look for option 66 in the DHCP response. If option 66
contains a valid IP address, a TFTP download will be attempted for a file named after the
device MAC address, e.g. "00908f0130aa.ini".
The configuration file loaded in this method is a one-time action; the download will not be
repeated until the device is manually restored to factory defaults (pressing the reset button
for 10 seconds while the Ethernet cable is not connected).
This alternative requires a configuration server at the customer premises.
TFTP access into the core network is not NAT-safe.
5.7 Option G - Configuration using AudioCodes EMS
AudioCodes EMS server functions as a core-network provisioning server. The MP-1xx
should be configured with the IP address of the EMS server as the SNMP Manager, using
one of the options detailed above.
As soon as a registered device contacts the EMS server via SNMP, the EMS server
handles all required configuration automatically, upgrading software as needed.
This alternative does not require additional servers at the customer premises. This
alternative is NAT-safe.
