Create a temporarily user in the <servicenumber>.teams.ipvoip.ch domain[edit | edit source]

None of your user will use the <servicenumber>.teams.ipvoip.ch, but as stated in the Requirements above, we need to create a temporarily user in this domain with the Teams + Phone System licenses in order to be able to create the CsOnlineVoiceRoute towards VTX SBC


  • Problematic: We wish to create a enableteams@<servicenumber>.teams.ipvoip.ch to enable Teams connection towards VTX VoIP platform
  • Solution: Please follow the procedure below
  1. Connect to https://admin.microsoft.com/Adminportal/Home#/users
  2. Create a new user enableteams@<servicenumber>.teams.ipvoip.ch ( First Name: "Temp User" / Last Name : "VTX Teams" / Login : enableteams@<servicenumber>.teams.ipvoip.ch / No Admin Right / "Teams" and "Phone System" licenses / No need to remember its password, we won't connect with it).
  3. Wait a few seconds/minutes/hours for Teams to be enabled on this user https://admin.microsoft.com/AdminPortal/Home#/teamsprovisioning
  4. Now even after user is created you night need to wait minutes/hours before being able to create Voice Routing ( especially the New-CsOnlineVoiceRoute ), so if you can please wait 4hours, if not, try to create the routing, if you get error, try again
  5. Once everything is working ( routing + user mapping + incoming and outgoing calls ), you can delete this user to free up the licenses

Voice Routing : Create Voice Routing to allow your users to use VTX Trunk[edit | edit source]

You will only need to do voice routing setup once for all users
It will take several hours for Microsoft to create your domain after linking it in the Kiosk, so it is wise to wait a few hours before trying to create the routing. If it is not ready, you won't be able to login or Voice Routing will not work. So you will need to be really patient.
If the script displays a red error on New-CsOnlineVoiceRoutingPolicy, please read VoIP:Teams:Microsoft Management
Once Voice Routing has been correctly created without error, you can delete the user enableteams@<servicenumber>.teams.ipvoip.ch to free up its licenses, it is not needed anymore

Now you will need to setup a routing plan. You can use one of the following options to do it

  • Using a Powershell Script that will ask you questions
  • Manually in Powershell


Microsoft Admin Center - Up to 24h Latency for each setup


Create Voice Routing using a VTX Powershell Script VTX_Teams_Create_Routing_Rules.ps1[edit | edit source]

By default for security reason, it is not allowed to execute a powershell script downloaded on the internet, that is why you will need to open them with Wordpad to check what it does, save it and execute it afterwards
When you run the script, please look at all red warning errors that are being displayed, and use this wiki to handle any error. You can run the script several time in case of problem, simply discard the "duplicated" errors afterwards. Using the next manual section will help you see where the error comes from


  1. Download https://wiki.vtx.ch/media/VTX_Teams_Create_Routing_Rules.ps1 on your computer ( Right Click on the link / Download )
  2. Open it with Wordpad and use Ctrl-s to save it again ( to inform the system that it is local script )
  3. Execute it on your PC : It will ask you for these parameters and create the routing
    1. VTX Teams Domain : ex: 123456.teams.ipvoip.ch
    2. Your MS Teams Admin Credentials : ex: admin@COMPANY.onmicrosoft.com

Or Create Voice Routing manually in Powershell Command Prompt[edit | edit source]

If you prefer a manual setup, perform the following actions


  1. Open a powershell prompt on your PC
  2. Copy paste command below one by one changing the values in bold with your own
# Set Variables
$TeamsDomain = "123456.teams.ipvoip.ch"
# Connect to Microsoft Teams management and create all Voice Routing
Connect-MicrosoftTeams
Set-CsOnlinePstnUsage -Identity Global -Usage @{Add="CsOnlinePstnUsage-$TeamsDomain"}
New-CsOnlineVoiceRoute -Identity "CsOnlineVoiceRoute-$TeamsDomain" -Priority 0 -NumberPattern '.*' -OnlinePstnGatewayList "$TeamsDomain" -OnlinePstnUsages "CsOnlinePstnUsage-$TeamsDomain"
New-CsOnlineVoiceRoutingPolicy -Identity "CsOnlineVoiceRoutingPolicy-$TeamsDomain" -OnlinePstnUsages "CsOnlinePstnUsage-$TeamsDomain"
Set-CsCallingLineIdentity -Identity Global -EnableUserOverride $True

# Verify all setup ( You can compare it with the Debug Section in the wiki ) 
Get-CsOnlinePstnUsage
Get-CsOnlineVoiceRoute
Get-CsOnlineVoiceRoutingPolicy
Get-CsCallingLineIdentity

Number Mapping : Assign/Unassign numbers to Microsoft accounts[edit | edit source]

Now you will need to assign a number and a routing plan to each user with a "Microsoft 365 Phone System" license. You can use one of the following options to do it

  • Using a Powershell Script that will ask you questions
  • Manually in Powershell


Assign/Unassign numbers using a VTX Powershell Script VTX_Teams_Assign_Numbers.ps1[edit | edit source]

  2. Open it with Wordpad and use Ctrl-s to save it again ( to inform the system that it is local script )
  3. Execute it on your PC : It will ask you for these parameters and create the routing
