asterisk users - Jan 2005 - DHCP Attribute for TFTP server for Aastra 480i?

I have this Aastra 480i phone, and you can set the TFTP server IP address
manually in the phone, but there should be a way to have it find the TFTP server
information via DHCP. Does anyone know if this is possible, and if so, what is
the attribute I have to set on my DHCP server? Thanks!

I was testing one of those phones about a month or so ago, and ran into
the same problem. I think I read that upgrading the firmware corrected
that problem, and the tftp address was being used from dhcp.

If you are running some form of unix, then "man dhcp-options" may give
you the info you require. It all depends on what DHCP server you are running.

I used the below to do debian/gentoo network installs onto my SGI.

This is the entire content of my dhcpd.conf file but should be enough to
help.

ddns-update-style ad-hoc;
group {
        # IP address of TFTP/NFS server
        next-server 10.10.10.1;

        subnet 10.10.10.0 netmask 255.255.255.0 {
                # Allow BOOTP Requests
                allow bootp;
        }

        host sgi {
                # Ethernet address of the client machine
                hardware ethernet 08:00:69:08:2F:46;

                # IP address to assign
                fixed-address 10.10.10.2;

                # The name of the file to be downloaded by the PROM
                #gentoo filename "ip22-r4k-20040215.img";
                #debian filename "tftpboot.img";
                filename "tftpboot.img";
        }
}

You'd like to do it instantaneously, but that's too slow.

Boot Server (TFTP) is usually option 066 in dhcp, in many cases it
requires a hostname, not an IP address, so you have to make sure that
the device is DNS aware and that the hostname you specify in option 066
is in the same DNS that phone uses. If option 066 does not work try
exploring option 150 on your DHCP server.
 
Not sure if this applies to the Aastra phone since I do not have one to
test, but let us know.

One thing of note: if you're using Linux as your DHCP server, you'll 
want to make sure you've got version 3 of the DHCP server, otherwise, it 
doesn't deal correctly with some of the attributes.  For Debian, it's 
the dhcp3-server package.
