Sefautil and common area phones

If you are using the desktop version of Lync you can set forward and no answer destination in the client. But if you have setup a common area phone you don't have those options. Sefautil to the rescue...
I have read some articles and posts by others that says that Sefautil and call forwarding settings does not apply to common area phones. But that is not true with Lync 2013. Sefautil can be used to setup call forward and no answer destination for a common area phone.
