Hi Lalit, if DHCP settings are correct, try testing connectivity from CUCM server to the IP Address assigned to the non-registered phone.

Do you have configured VLANS?, make sure that there are not routing issues.

Also, you can try registering another functional phone on the same physical port where the 7936 is connected.

All the best.

I'm having the same problem with a 7936. After changing from CCMExpress to CUCM 7.1(2a) all phones register and update to the new CUCM, only the 7936 wouldn't register (could not contact tftp). But it could, I sniffer the traffic, DHCP (also from CUCM) works and the phone get its configuration file from exactly that tftp, but it would take the offered callmanager. (Phone is HW 2.0 and SW 3.2.20)

If nobody has an idea for it, I would open a case for this issue.
