Yes, I am having Cisco Call Manager 4.1.And I am having Cisco 7940 and 7902 phones.Here the scenario is that phones are taking ip from the DHCP pool when it register with call manager.suppose that i power off the phone for three days,again if i power on arbitarily its take another ip from the DHCP pool.So i want to restrict the ip with the MAC address of the phone.

Thanks

Depending on what you are using as your dhcp server, you can "reserve/assign" the ip address for a particular mac address. This way, the specific phone will always have the same ip address.


If you are using an ios device as a dhcp server, see the below doc on how to statically assign them:
