New BCM 450R6. 1220 would not boot at all. Tried set on BCM50R3 and booted fine,downloaded FW, and came up to where it asks for a DN. Took phone back to 450, it boots but says "server unreachable". Checked setting in phone and they are all fine. BCM has given out IP as it is in lease info. System has latest PEPs. Can anyone help?
