Audiocodes Mediant 2000 - BootP

Hey guys, I have one particular Audiocodes Mediant 2000 SIP / ISDN gateway. It seems that it doesn't have firmware on it, as it simply sits there sending BootP requests. ( found by watching packet captures from its ethernet ) Does anyone have any insight into the DHCP options AudioCodes require, to make these guys grab a new firmware via TFTP ? I've got BootP responses going back to it, but for the life of me, I can not make it request anything over TFTP. I have looked at trying the Audiocodes TFTP/Boop application, but the version I have won't run on any recent windows. if anyone has the BootP application ( and how to make it run ), that would be great. if you have any info on how to make the device grab a new firmware via standard DHCP / TFTP config that would also be brilliant. On another note, the manual says this has a serial port. does anyone know where to find this ?? :) -- Sincerely Jay Binks

Hi, As far as I remember you need to send the IP address of the TFTP server in the tftp option of bootp/dhcp. Then check the log on the tftp server for the files it requests. /Morten On Tue, Jan 24, 2017 at 12:53 PM, jay binks <jaybinks at gmail.com> wrote:

This sounds like the Preboot Execution Environment (PXE) boot process. Overview here: https://en.wikipedia.org/wiki/Preboot_Execution_Environment <https://en.wikipedia.org/wiki/Preboot_Execution_Environment> The simplified process is this: client sends boots/dhcp request dhcp server replies with address assignement and options - 60, 66 and 67 are most likely what you need client uses TFTP to download boot image client boots image Option description here: https://www.experts-exchange.com/articles/2978/PXEClient-dhcp-options-60-66-... <https://www.experts-exchange.com/articles/2978/PXEClient-dhcp-options-60-66-...> There are detailed descriptions for setup on various Linux distros - search for "{distro-name} PXE" For Windows, you would set the options in your DHCP server. ?
