Thought I would post this, not sure if its been answered

I struggled with this for awhile , but it turned out once I did the following I was able to setup the Map_Users.ps1

1 - Make sure all the users are in the default Global Org under Users - Policies in the Teams Admin



2 - Make sure in the user licensing (under admin.microsoft.com) you have assigned the Voice License

3 - In user licensing under apps *UNCHECK* Domestic Calling Plan (probably any calling plan)

Wait an hour or so after making these changes








Once I did this and waited a little bit I was able to assign the Set-CSUser properly and then able to make/receive calls.

Dang, I went through everything I could find on 3cx including the 3 videos and didn't see this one ... ahh sad face

Well hopefully I help someone who couldn't find that either as I know its early but going through stuff bounced me around alot.
