Create a temporarily user in the <servicenumber>.teams.ipvoip.ch domain

• 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

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

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

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

Dial Plan for Emergency Numbers + Short Numbers + Special Setup

• History:
  • 2026-01-21: The addition and deletion of Emergency and Short number is directly included in version 4.7+ of the create routing and delete routing script
• Information: By default if you try to dial a number, Teams Client will always try to normalize it in +e164 mode adding your country prefix like +41 or +33 to your number
• Problem: If you call an emergency number like 112 or a Short number like 10XX or 3XXX or 116xxx or ..., it will add an invalid country prefix
• Problematic: Add Dial Plan entries not to alter number dialed
• Symptoms: Within the Teams Client, you will directly see if the number you are typing is being transformed with a county prefix or not. If it is transformed, you are missing the following rules
• Dialplan Documentation: https://docs.microsoft.com/en-US/microsoftteams/create-and-manage-dial-plans
• Dialplan Web Admin Teams Management URL: https://admin.teams.microsoft.com/one-policy/settings/dialplan
• Solution: Use one of the solution

1. Run again the create routing script on last version (4.7+) on your domain to create the rules
2. Or Connect to Dialplan Web Management interface to add them manually

Number Mapping : Assign/Unassign numbers to Microsoft accounts

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

1. Download https://wiki.vtx.ch/media/VTX_Teams_Assign_Numbers.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 Admin Credentials for : ex: admin@MSDOMAIN.onmicrosoft.com
   3. The MS Team user email : ex: first.last@MSDOMAIN.onmicrosoft.com
   4. The Telephone number you wish to set : ex: +41225661234 / or leave string empty to unassign number from user

Here is a list of screenshots to see how the script works

Teams Assignment - 1st Warning - Is routing OK ?	Teams Assignment - Enter the Teams Domain Provided by VTX
Teams Assignment - Enter Teams Admin email	Teams Assignment - Enter Teams User Email
Teams Assignment - Enter Teams User Phone Number or use empty string to remove the number	Teams Assignment - Disable voicemail on the user ?
Teams Assignment - Setup another user ?	Teams Assignment - List all user setup ?
