"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

There is no way to do this with any features builtin. You could create a XML service that has a sort of lock screen but the users would have to run it manually.

You can also consider extension mobility. That would require users to login to the phone.

Can u plz brief me abt extension mobility and how it can achieve the requirement
The Extension Mobility feature allows users to configure any Cisco IP Phone 7940 or Cisco IP Phone 7940 IP phone as their own, on a temporary basis, by logging in to that phone. Once a user logs in, the phone adopts the user individual user default device profile information, including line numbers, speed dials, services links, and other user-specific properties of a phone. For example, when user A occupies a desk and logs in to the phone, her directory number(s), services, speed dials, and other properties appear on that phone; but when user B uses the same desk at a different time, his information appears. The Extension Mobility feature dynamically configures a phone according to the current user.

You didn't mention what platform you are using, but here is an article about configuring EM on CME:

We are using ccm4 and 7960 ip phones..thanx for the info abt em but I was thinkibg of using any existing feature for a single user profile
There is no other existing feature that can accomplish what you need to do. This is the closest thing.

As jimartinexiii said extension mobility would work for you.. Set up a basic phone profile that allows users to gain no functionality accept for 911 calls, then let the user's log into their extension mobility profiles.
