Cisco IP phone not registering

Hello,

some of the Cisco IP phones are not getting registered to the cisco call manager.

I cleared the MAC address on the port where this phone is connected, reset the port, and checked the VLAN where the phone is getting connected. Also, I can see that it is getting an IP address from the DHCP lease.

I tried everything but nothing is working, any suggestion please that my help.
