Hi Hari,

Is this the fresh installation?

if yes, please check Call manager/tftp service is running or not.

Re: IP Phone showing unregistered in CUCM

Check the DHCP Pool (Scope) for option 150 which will need to have the CUCM IP address.

Verify the TFTP service on CUCM.

Check if the phone has a ITL file (Settings>Security Configuration>Trust List>CTL) from a previous registration. If it does, remove it (**# to unlock the phone)
