IP Phone unable to get IP Address

Hi,

     i am encountering a weird situation . bunch of IP phones are not getting IP address from DHCP server phone model is 7906. there are bunch of ip phones having the same problem. i tried so many different things but could not solve the issue. DHCP is working fine, ports are OK. DHCP is configured on publisher and we are using CUCM 6.1 version

please suggest advice Thanks...

The DHCP service is started on the CM?

If possible (for testing) make an IOS DHCP server, this gives you good DHCP debugs.

Re: IP Phone unable to get IP Address

Are the phones not getting IP addresses or not registering with cucm?

The Cisco IP Phone is receiving the DHCP server address?

The Cisco IP Phone is receiving the IP address, subnet mask or default router address?

The Cisco IP Phone is receiving the TFTP server ?
