Thanks Guys, I had not realised until the last couple of days that DHCP did more than just providing the IP address to the client. I have been happily just doing that for a few years now without anything other than my Router providing the DHCP function. It's only now that I have taken the plunge into IP telephony that I realise that it can do more and for Cisco phones, should provide the address of the TFTP server. My work-around at the moment is to used fixed IP addresses in the phone for it's own IP address and the TFTP server - not as neat as I would like, but it works. I will look at a better long term solution with a different DHCP server (as already mentioned earlier in this thread). Looking on the bright side, I have got the phone provisioned - though I'm still working out what all the options are, but it is working. As Brian has spotted - my reference to a 7540 was an error - I got in right in the body of the original post, but not when I edited the subject line - oooops - sorry. The phone is a 7940 ! regards Dave ----- Original Message ----- From: "Karl J.

Yeah, roger that... Here is an excerpt from the page I did on the Cisco 7960G HowTo:

It's for Linux, but you'll get some good pointers on the TFTP option you're looking for. I haven't provisioned any 7540's... Good luck!

Metik,
thanks a lot for the tip, I will certainly look at it, particularly if it does DHCP too.
At the moment, I use my ADSL Router to provide DHCP to the network but I've just discovered that you can't configure options in its DHCP server to point to the TFTP server for the phone. At the moment, I have to have the phone set to a static IP address to be able to configure the TFTP server address which is not as flexible as using DHCP. I had thought about changing over to use Windows Server DHCP services but it sounds like ttpd32 would do the trick.
I just need to decide whether I want all of my machines to rely on getting their IP address from another PC - it feels like having DHCP in the router is more robust.
