Yes.
For example I have a group called "support" with 4 extensions. My extension is the administrator with all options checked. I can do things such as barge, whisper,etc. But I dont see where I can edit the status of another extension.
If I right click on another extension there is call, chat, call mobile, vm, intercom, log in queues, and create conference. I am sure I am just not looking in the correct place.
