Let's first login to the Trifecta Teams app portal with our Microsoft credentials.
Once we are logged in, we will want to go to Users to see the list of people in our company.
We first want to make sure that we have activation credits available to proceed with our change.
If we are at zero or below, then we will need to purchase more credits. Otherwise, Let's find out user and click edit.
At this point we want to decide if we want to enable the voicemail and decide what calling permissions we want to assign to the user.
For my test user, I am going to enable voicemail and Choose a phone number from the list. If you do not have any phone numbers, then please check this article out.
Now we want to choose 'Tenant Dial Plan' which helps us identify our location. After all of our settings have been set, you will see something similar to below.
Go to the bottom of the edit card and click Save and we're all done.
You will now see the new changes show up in your User section. As of now the change is being pushed to Microsoft. You will not see the changes in your Teams client for another 15-60 minutes on average.
