cisco 7940 TFTP timeout

can someone help me please, I'm a newbie and this phone is driving me insane.

I originally had a problem of Protocol Application Invalid on the display of this phone, thanks to Marks help I've managed to make small progress and now the phones' display is stuck on 'TFTP timeout' Obviously the phone is trying to download via TFTP but I can't TFTP the phone at all. My TFTP server (pumpkin v2.7) just keeps failing. None of the buttons on the phone do anything, they appear to be dead. I've ascertained the IP address of the phone but how do I know what IP address it is calling to for TFTP?

The phone is attached to the f0/0 port of my router and I set the port up with:

ip dhcp pool test


option 150 ip



From what I can gather the phone's ip is When I first turn the phone on I get 'Configuring VLAN', then I get 'Requesting Configuration' and then I get 'TFTP timeout'.

thanks for any help.

Hello Tony,

Would you mind posting(or attaching) your "show run" and "show ver" of your switch(or switch interface of the router) and router. Also, can you post the topology or layout of your network and the version of the CUCM[E].
