Microsoft has released the August cumulative update for Lync Phone editions and unlike the ones that released before, this one has addressed some much anticipated features such as,

• Update enables users who are not enabled for UC or EV to sign in to Lync Phone Edition telephone
• The lock feature does not prevent users from making calls on a Lync Phone Edition telephone

After applying this update, Lync phone edition device can be signed in to a user who haven’t enabled fro Enterprise Voice. And getting one step closer to the PBX world by seeing the “Phone Lock” feature to not to allow dial outs while it’s locked. The emergency calls however will be able to dial out as long as it’s configured in location Policy.
