Bjorn,

Save yourself the trouble with the console cable. Take a spare PC, install [EMAIL PROTECTED], setup the included DHCP server, install the appropriate files in the /tftpboot directory, and plug the PC and the phone into the same switch.

Voila!

Thanks for the suggestions everyone!

The thing is, when I run tcpdump, this phone never really requests anything
as far as I can see.

The IP-address serving is not handled by the Asterisk box, which is on its dedicated IP-address, but by a consumer type SMC Barricade 4-port router.
There's no option to define boot tftp on this device.

I'm thinking of getting myself a console cable for the phone, and see if I'm able to log in and set the variables using that. Don't know if these cables
can be purchased in stores or if they'll have to be hand made..

My biggest problem is that I simply do not know which IP-address the phone
is searching for - if its searching for any IP address at all.

Thanks again, have a great weekend.

Bjorn

Hello!

The issue is simply that I don't know which IP address the phone
tries to
connect to. I am not very familiar with dhcpd (never put it up by
hand), so
I'm not sure how the below would help me, but from what I can tell,
I still
need information on which IP-address the phone is trying to find
its tftp
on, right?

I have put this in my dhcpd.conf to make sure my cisco
phones connect to my TFTP server:
server-name "192.168.2.1";



I'd be surprised if that worked... the server name is for.. um.. the
name of the server :)

Try:

option tftp-boot-server code 150 = ip-address;
option tftp-boot-server 192.168.44.3;

Bjorn,

The phone will use whatever TFTP server your DHCP server tells it to
use. That is what the above line "option tftp-boot-server" is
supposed to do, it tells your DHCP server what address to give your
phone. If your DHCP server does not give the phone an address, and
you have not specified one manually through the phone's settings
interface, then it will  (in my experience) default to the same
address as your DHCP server.

What are you using for a DHCP server?

Can you enter the settings interface of the phone if you leave the
ethernet disconnected? (If so, manually specify the TFTP server
address.)
