Question about Cisco 7940 IP Phone
I have a two cisco CME's and 7940 phones. The router configs are the same except for the IP's of course and one of the routers will not let the phones register. I am using DHCP and that is configured the same on both routers. The vlan on both switches is also configured the same. One set works but the other will not register the phones, they get stuck in Configuring IP. Each phone sees the vlan but does not go any further. The flash on both routers is the same and configure cnf file is in both of the router configs. I am at a loss for why one is working and the other is not. If you have any advice please feel free to help.
Did you check the TFTP settings on the IP phone? You may need to disable DHCP on the phone and assign the TFTP manualy or make sure the correct TFTP server is assigned.

Im my case the phone does not seem to be pulling the config properly because it can't locate the tftboot server.. check out my solution: http://princechavez.net76.net/?p=39

I'm having the same problem. I noticed that when you plug in different laptops it will reset the cisco voip phone doing that IP Configuration thing forever. :|
