I've got three 7940 phones loaded with P00308000400, connected to a 2651XM router with cme 4.03 and I occasionally get a problem starting one or more of them up in that the startup hangs at 'Configuring IP', and when it's stuck there the display briefly flickers 'Configuring CM List' every three seconds or so. I've been through the phone settings over and over, I can't alter or hard code anything because no buttons on the display allow me to, and the phone is hung midway during the boot anyway. I've cleared the dhcp bindings in the router, factory reset the phone, reloaded the router but still the phone hangs. When I press settings/network config I do see an IP address but I also see 'DHCP Address Released NO'. How can I change this to YES? When I watch the phone bootup in wireshark there are lots of repeating dhcp requests and acks but the phone is still stuck. Thanks for any help.
