Error while adding phone numbers on

Occasional Visitor


I want to add phone numbers on . I want to do it for Canada based customers of mine. While trying to add a number, I am getting below message "We can't do this because your organization is missing a Phone System license. Buy more licenses and please try again. If you continue to have problems, contact"  .. I am attaching the screenshot as a reference:


Note: I have already purchased "Office 365 E5"


Please advise.

Have you had any progress on this?  I am seeing the same error for the last 2 days

@John_Strait -- I too am trying to add a conference bridge number to add to my users' invitations. We have E3 licenses, already too. When searching for 'phone system license' I get nothing back on the available products within the administration portal. 

@MJSunny Hello, there is a Office 365 E5 license without the Audio Conferencing add-on. Are you sure it is included in your plan?

Having Exactly the same issue here in Netherlands,

Did anyone found a fix/solution already?


Should all users in the tenant have a Phone System License?
