This same process can also be used to download files from a custom distribution server for use with the Lync Qualified releases, as covered in the next section of this article , but this central distribution point may not include the most recent versions released depending on what features or capabilities were introduced in the last release.

In Denmark we use a system called Nem ID (Easy ID) that we use to log on to important websites like for example (in my case) my bank account, and the like.
For this reason it may be necessary to download the available software package for the 4.1 release and then create a custom distribution server to point the devices to.
