OK - You mentioned the 3220c. Given that, can we assume you have a CTX/CIX? If so, your station must be set up in system programming as the Administrator phone. There is also a password attached. If it is not, then you cannot make name changes.

I would first contact the installer to find out if any station has been assigned as the Administrator. Then if (s)he cannot tell you how to change the name, come on back here.
