Ok I have removed the phone killed it in dhcp but it still comes back with the same IP address. How can you change the IP on the phone?

Greetings-

Well - don't completely understand the context of your scenario based on your post ... however have you considered using MAC address reservation(s) on the DHCP server, to help "force" the phone to go to a specific IP address (or different IP address)?

Sorry didn't answer sooner I just took the phone off the network until the DHCP lease ended then it got a new IP. But what I wanted to do is clear the IP from the phone manually or do a IP release like on windows. I did do a reservation for the phone but it just keep grabbing the old one for some reason until the lease ran out.

I was getting intermittent IP address conflicts on the phones and occasionally a PC. Resetting the phone and killing the DHCP lease did not help.

After many WTFs, I found the ATAs were using Static IPs in the DHCP address scope. I created a DHCP reservation for the ATAs and all is well.

Check to make sure you do not have a static device using an IP in the DHCP scope.
