The most common and (on paper) most simple request you will get regarding TAC is to assign a new "landline" number to a user. Generally they're a new starter, but could be a part timer turned full time, a casual we've absorbed into the fold. To have Teams voice enabled the user will need an E5 security license. 


Most of our users will have this, but some casuals or non-office workers do not so bear that in mind.


Very rarely a user has an E5 assigned and yet does not show as able to be assigned a number due to "Teams voice not being enabled".

If this happens, check the article below and fire off the PowerShell and it will resolve the issue.

A request has come in for a user to have a Teams number assigned; lets get to work.


Head to Teams Admin Centre and down to the "Voice" section. Open up the "Phone numbers" section.


Now we should be able to see a large list of numbers. 







These are ALL phone numbers in Teams. "User assigned" and "Unassigned" are self explanatory and "Voice app assigned" means the number is being used as part of a "Resource Account". These relate to the organisations "Call Queues" and "Auto Attendants". File that knowledge away for now, that's terminology you'll become familiar with as you dive deeper into TAC.


This includes all our Call Centre (Cirrus) numbers and therein lies the problem: just because a number is showing as unassigned in this list does not mean it is unassigned.


The first thing I'd do when presented with this page is to add an additional column to the table. Click the settings cog in the top right of the table.


 


Once there, toggle the "Assigned to" switch to on. This will show who the number is assigned to without you having to click further in.



Now that's out the way, lets set a filter so we can get all the unassigned numbers showing nicely.


Next to the settings cog there are three little lines. Click here and open it up.


Change the "Filter" option to "Assignment status" and "Value" to "Unassigned". Hit apply down the bottom left and your big list of numbers should get shorter.





As mentioned before, this unassigned list will show all Cirrus numbers as unassigned as well. Below is our main Customer Service number showing as unassigned, for example.


The numbers that are free and genuinely unassigned begin with "580*" as these were a new number range given by Gamma as part of our migration.


There are, of course, other numbers that are free and available, and they can be found by searching the number in SIP Trunk Call Manager. You'll need a log in created for this so if you don't have one, just crack on with a 580* number.


Select the number you like and then hit "Edit" to bring up the options to assign the number to your user.




Type the person you need to assign the number to, click their name and hit "Apply" down the bottom left.




Once you've selected your user a new option will appear to "Email user with phone number information". Do that, but be sure to include the number information in your reply to the requestor who raised the ticket anyway.





And that's it. Hit "Apply" and then your changes will be saved and we're done.
