I would appreciate to have an option to disable PIN authentication for hot desking. We are a small company where everyone knows everyone and we do not use individual caller IDs for external calls. Therefore impersonating someone on the phone will not work anyway. If someone would try this on an internal call... well nice joke, but we know each other well enough to instantly recognize the voice of the person who is really speaking. On an external call the callee won't see any difference regardless wich extension is used internally. And for unauthorized visitors this PIN won't be any protection at all because usually there will be some extension already logged in when the office is open for business. Besides, using the phone would be the least of my concerns if someone manages to gain unauthorized access to the office.
