Currently have had a few calls where there have been a few issues adding phone numbers to resource accounts for Auto Attendant. This is just a quick guide that might be of some use.
Pre reqs if you will.
- Purchase the virtual licenses for Virtual user
– Sign into the M365 admin center
– Go to Billing –> Purchase Services –> Add-on subscriptions
– Scroll to the end to find the “Phone System-Virtual User” license. Select “buy Now” this is a free license.
- Make sure you have the service numbers ready to assign to your resource account.
– Admin center –> Teams –> Voice –> Phone numbers –> add –> fill in the necessary information.
Now that we have the licensing and numbers in place we need to create the resource account. The official documentation for this can be found here . My lab is hybrid so I have to first go to the 2019 Skype powershell and run the following cmdlet:
New-CsHybridApplicationEndpoint -DisplayName resourceblog -SipAddress sip:email@example.com -OU “CN=Users,DC=uk2us88,DC=com”
You can either wait for ADD to sync or you can force it using this cmdlet:
Start-ADSyncSyncCycle -PolicyType Delta
Once AD has synced and you can see your user in the list in the “Active user” list go ahead and assign the license we gathered in step 1. “Phone System-Virtual User”
Once the user has the license now its time to configure your Auto Attendant.
Teams portal –> Voice –> Auto Attendants –> Add
Fill in all the information as needed. Dont worry about the phone number yet just complete the wizard and assign your resource account.
Now once you have completed this you can go under your resource account found under Org-Wide Settings –> Resource accounts –> Newly created account –> Assign/Unassign.
At this point we have setup the resource account, AA and assigned the number. You should be able to call the number and test to verify that AA is indeed working.
In a future blog I will introduce Call queue and Shared voicemail
