Correct.

Do you have any ATAs registered in CUCM?  If yes do a settings comparison.  If everything looks good in the profile and Device security Profile under Protocol Specific Information make sure your DHCP is sending OPTION 150 with the TFTP server addresses.

The problem is solved after configure  TFTP server address manually via IVR.

For IVR, hit ****
Enter password, default is 24726
Enter option 221 to configure TFTP server IP address
