Email OTP Verification coming to Teams Meetings

Microsoft introducing a new security feature in Teams that will enable enforcements of Email OTP verification for meetings. This new policy, "Anonymous users can join a meeting after verifying," will be available in the Teams Admin Center for all organizations. This feature is available only for meetings created by organizers with a Teams Premium license. The feature is in public preview, but should be rolling out in GA any time soon. The update will roll out automatically. Admins should consider to update the new meeting policy setting from “By e-mail code” to “No” by mid-February if they wish to continue blocking all unverified users (If "No" is the current setting). The policy is described in this article .

A new update to "Assigned Numbers Script"

Thanks to some bug reports on the original post, I have now edited the Assigned Numbers script.

Hopefully, it will now give you a correct output of users with a lineURI.
I used this as an excuse to clean up the script, and sign it, so it can be run directly in your lab without interaction.

I have also tested and verified it in a Lync 2013 setup

The script has been moved to a new location, and can be found here
