Why do you want bind IP with MAC address ?

Did you preface the 12-digits MAC address with a 01, in the format 01XX.XXXX.XXXX.XX? That, apperently, is the format that the Cisco DHCP requires.

we want our ip phone should have uniq IP add. so we can monitor IP phone ...

it's also possible through static IP add but in our 7902 IP phone there is no display only we can hereing voice and give IP but this is very tough process..so we want to bind it in our dhcp server....

You do not need a static IP to monitor phone. Doing so only introduce unnecessary management overhead, and none of the large installations in the world does that.

Monitoring is better done by either MAC address, or the extension number.
