Lync and Private Line

There are a lot of new features available in Lync, and one of them is called “Private Telephone Lines”. A complete review of this feature can be found in this TechNet article:

When dialing that number, it won’t work.

When calling someone using his/her private number, the following system notification pops up:


Whereas a call to someone’s enterprise voice number, shows the following pop up:

    Hi Ilse, great topic. Just created a private line in my lab for a user. it works great. I also use the cmdlet to get a table with al users that have a private line. Looks good.

    but…. i can't find in any doc how to remove a private line. do you know how to remove a private line?

    Hi – thanks for the great post, very helpful.

    Is there a command to show all users who have a private line?

    This would be really useful for housekeeping.
