Introduction[edit | edit source]

The purpose of this page is to explain how to setup and manage a VTX Teams Virtual service to integrate it within your Microsoft 365 domain. A presentation of the service is available at https://www.vtx.ch/fr/corporate/telephonie/teams-virtual and https://www.vtx.ch/de/corporate/telefonie/teams-virtual

How does it work ?[edit | edit source]

VTX Teams Virtual allows to integrate Teams accounts into the VTX VPBX service as if they were simple softphones ( Ex : VTX DesktopControl and VTX MobileControl ) allowing to provide an hybrid environment. You can keep having some users using SIP phones only, some other users using only Teams, and some others using both SIP phones and Teams Client in the same time.

Technically, Microsoft Teams acts as a "PBX" with one main auto configured SIP trunk connection towards VTX Telephony platform handling calls and numbers hosted on Teams. VTX Virtual PBX service provides one connection per phone number allowing phones to be used in different locations and adding several features like groups, headnumbers, timecondition, BLF, IVR, Dedicated Confrence on top of them. The power of the VTX Teams Virtual Service is to merge these 2 services together integrating a number of the Teams Connect as if it was any SIP phone within the VPBX.

So you could be using in parallel a Snom/Yealink/Gigaset SIP phone + VTX Softphones ( MobileControl + DesktopControl ) + Teams ( on PC and Mobile too ), all these phones would ring if you receive an incoming call and all these phones would allow you to call out

Please refer to VoIP:VTX_Teams_Virtual#VTX_Teams_Virtual_value_added_features to get the list of all Value added features of VTX Teams Virtual


Setup Process Overview[edit | edit source]

Here is the process that will allow you to setup the service

  1. Follow requirements below VoIP:VTX Teams Virtual#Requirements
    1. Order VTX Teams Virtual: You need to order a VTX Teams Virtual service at VoIP:VTX Teams Virtual#VTX_Teams_Virtual
    2. Order Microsoft 365: You need to have or order a Microsoft 365 account at VoIP:VTX Teams Virtual#A_Microsoft_365_domain_and_accounts
    3. Powershell: Use a Windows PC or Server to create routing and assign numbers at VoIP:VTX Teams Virtual#Microsoft_Windows_PC.2FServer_with_Powershell
  2. Setup Domain in VTX Kiosk: You will link your VTX Teams Virtual domain with your Microsoft account at VoIP:VTX Teams Virtual#Link_your_.3CSERVICE_NUMBER.3E.teams.ipvoip.ch_Domain_between_Microsoft_and_VTX_Telephony_platform
  3. Create enableteams temporarily user : Create a temporarily user to allow creating routing at VoIP:VTX Teams Virtual#Create_a_temporarily_user_in_the_.3Cservicenumber.3E.teams.ipvoip.ch_domain
  4. Create Voice Routing: You will create the Voice Routing within Microsoft Teams platform at VoIP:VTX Teams Virtual#Voice_Routing_:_Create_Voice_Routing_to_allow_your_users_to_use_VTX_Teams_Virtual
  5. Assign Numbers: You will assign numbers to your users and start using VTX Teams Virtual service at VoIP:VTX Teams Virtual#Number_Mapping_:_Assign_numbers_to_Microsoft_accounts
  6. Test Numbers: Use the VTX xx 566 xx xx test number to validate your setup BEFORE the porting date
  7. Port Numbers: Once your setup is ready, you will ask VTX to enable the service with your real numbers ( Ported Numbers or VTX Numbers ) in order to connect "Teams" to the "standard" telephony networks. This process allows to migrate your telephony service without interruption.

VTX Teams Virtual Kiosk Management[edit | edit source]


Hardware Management Module : Assign the Microsoft Teams Virtual license[edit | edit source]


You can enable or disable receiving calls on your Microsoft Teams client by enabling or disabling a "Microsoft Teams Virtual" license in the Hardware Module
  1. Connect to VTX Kiosk Hardware Module with the Admin Credentials of your VTX VPBX service => https://kiosk.vtx.ch
  2. Go in the manage my IP Phones section => https://kiosk.vtx.ch/VoIP/ManageToIP.aspx
  3. Assign the Microsoft Teams Virtual license to the needed numbers


Manage my IP Phones module - Assign a Microsoft Teams Virtual license to one number


Link your <SERVICE_NUMBER>.teams.ipvoip.ch Domain between Microsoft and VTX Telephony platform[edit | edit source]


You need to have assigned at least one "Microsoft Teams Virtual" license to one of your user to be able to access this module
By setting up the license to your 1st user, many actions have been automatically done to create the trunk on VTX side. Now you need to link it with your Teams Environment
  1. Connect to VTX Kiosk Hardware Module with the Admin Credentials of your VTX VPBX service => https://kiosk.vtx.ch
  2. (optional) Go in the manage "Your Virtual PBX" section => https://kiosk.vtx.ch/HuntGroup/Choice.aspx and select the VPBX you are setting up
  3. Click the TEAMS VIRTUAL Setup button ( cf below ) => https://kiosk.vtx.ch/VoIP/ManageTeams.aspx
  4. Follow al the setup stage carefully
Click the Configure TEAMS VIRTUAL icon to access to the Domain Link wizard
Follow the setup wizard in the Kiosk


Microsoft Teams Management[edit | edit source]

Connect to Microsoft 365 Admin Portal[edit | edit source]

You can use this interfaces for the Domain Management, User management, License management and Software Management

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:VTX Teams Virtual#New-CsOnlineVoiceRoutingPolicy_-_Cannot_find_specified_Online_PSTN_usage
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

# Logout
Disconnect-MicrosoftTeams

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]

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
  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 ?
Teams Assignment - 1st Warning - Is routing OK ?

Or Assign numbers manually in Powershell Command Prompt[edit | edit source]

  2. Copy paste command below one by one changing the values in bold with your own
# Set Variables
$TeamsDomain = "123456.teams.ipvoip.ch"
$TeamsUserEmail = "first.last@MSDOMAIN.onmicrosoft.com"
$TeamsUserNumber = "+41215661234"
# Connect to Microsoft Teams management and assign number and profile to the user

Voice Dial Plan[edit | edit source]

Add a dialplan to match 4 digits extension with their +e164 number format[edit | edit source]

  • Problem: Teams will only allow you to call +e164 numbers, and if you do not have a number with the correct format, it will automatically add a +41 prefix ( country depending of the country of your user ) . So you are not able to call other extensions belonging to the VPBX with their extension number
  • Problematic: You would like to add some dial plan mapping to allow this
  • Solution: Follow the procedure below
  1. Read https://docs.microsoft.com/en-US/microsoftteams/create-and-manage-dial-plans to understand how it works
  2. Connect to https://admin.teams.microsoft.com/policies/teamsdialplan
  3. Edit the Global Dialplan to add mapping based on your needs
    1. Add a "Normalization rules" based on your needs. PS: There is a nice wizard to help you build it
    2. Ex: Here in the example we are adding a mapping to map extensions in 84xx format with +412287984xx
  4. You can test your extension mapping with the test tool

Delete Voice Routing[edit | edit source]

Delete Voice Routing using a VTX Powershell Script VTX_Teams_Delete_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
To delete the Voice Routing Rule, the script will need to make sure no more user is still using it, and will try to unmap numbers and VoiceRoutingPolicy of users using the MSTeamsDomain that you are dismantling


  1. Download https://wiki.vtx.ch/media/VTX_Teams_Delete_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 delete the routing
    1. VTX Teams Domain : ex: 123456.teams.ipvoip.ch
    2. Your MS Teams Admin Credentials : ex: admin@COMPANY.onmicrosoft.com


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

Here are the commands you can use to delete the Voice Routing if you wish to migrate service somewhere else

You will only be able to delete these entries if no user is using the CsOnlineVoiceRoutingPolicy


  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
Connect-MicrosoftTeams

# Delete the Voice Routing
Remove-CsOnlineVoiceRoute -Identity "CsOnlineVoiceRoute-$TeamsDomain"

Verify number provisioning in MS Teams app[edit | edit source]

It might take some hours ( up to 4h in our tests) to be able to see your number in the Teams app even if you see the number in Teams Admin web interface. You can try to restart the app to speed it up
  1. Verify the number on the MS Teams app
    1. Open the MS Teams app
    2. Go in the Calls section ( if you do not see it, then the "Phone System" license is not correctly set )
      1. (Mobile) You might get a popup informing that you have a new license and that app needs to be restarted
      2. (PC) Restart is not supposed to be needed, if you have waited a long time, please try to exit the app and start it back
    3. Verify that you can see the phone number in the Call section and that you can pass incoming and outgoing calls

FAQ[edit | edit source]

General Questions[edit | edit source]

Where can I find Microsoft Teams Admin and End User trainings ?[edit | edit source]

What are the differences between a "Teams Connect" and a "Teams Virtual" ?[edit | edit source]

Teams Connect Teams Virtual
Short Description VTX handles "only" the connection between Teams Cloud and the Telephony Network allowing you to operates real phone numbers on your Teams Client Teams Virtual allows an hybrid environment with SIP Phones and Teams Phones

The Intelligence remains handled in the VTX Kiosk

Analogy Like a VTX ConnectPBX product but to be used only with Teams Cloud ( preconfigured for Teams by VTX with a lot of automation ) a VTX VPBX service allowing you to use MS Teams client in parallel of normal SIP phones
VTX Service and Licenses Needed a "Teams Connect" ( billed per number of concurrent calls + number of numbers )

N/A per user

a VPBX Service ( billed per number of numbers )

a "Teams Virtual" license per user

Microsoft Licenses Needed Microsoft Teams per user

Microsoft Phone System per user

Microsoft Teams per user

Microsoft Phone System per user

Pros - Simple and Basic solution from VTX to add real numbers to your Teams accounts

- "Cheap" solution to use Microsoft Teams

- Allows an hybrid solution if you do not wish to have all your users and landing Zone to

use Microsoft Licenses.

- You can use a mix of simple SIP phones ( Gigaset, Snom, Yealink,... ), VTX Softphones (DeskopControl / MobileControl), Teams Softphones and Yealink Teams phones within the same user or on different users

- Allows to handle all Time Conditions and IVR and Groups within VTX Kiosk

Cons - Management of all intelligence in Teams Admin in less sexy than in the VTX Kiosk

- Doesn't allow to operate simple SIP phones within the same VTX service

Keep my @company.ch domain : Can I use VTX Teams service with my own Teams domain @company.ch ?[edit | edit source]

There is no need for you to change the domain of your users with a @xxxx.teams.ipvoip.ch VTX domain, your Teams users will stay with @company.ch domain
  • Problematic: You do own a Microsoft Teams domain like company.ch and you would like to integrate the accounts you have within a "VTX Teams Connect" or "VTX Teams Virtual"
  • Information:
    • When subscribing to a VTX Teams service, VTX will provide you with a teams domain like xxxx.teams.ipvoip.ch . This domain will be used to bridge your own Teams accounts ending with "@company.ch" with the VTX service. You will never need to force this domain for your end user
    • During the VTX Teams service setup, you will be asked to create one temporarily user with the @xxxx.teams.ipvoip.ch domain, but only one, and you can delete it as soon as service is running
    • The scrips provided by VTX will allow you to assign numbers to your @company.ch Teams users
  • Conclusion: Yes, you can use your own Teams domain @company.ch with VTX Teams service, no need to change your users domain

Multi-Provider : Can I use VTX Teams service in parallel of other provider services ?[edit | edit source]

  • Problematic: You do already have another provider that handles the telephony Direct trunking and you wish to also integrate a VTX Teams service
  • Information: VTX does provide a unique teams domain per service and also create unique Call Routing rules including this unique ID
  • Conclusion: Yes, it is possible to setup a VTX Teams service in parallel of an existing service from another provider. You will select which number is handled by which provider.

Migration[edit | edit source]

How to use Teams in parallel of my existing PBX ?[edit | edit source]

  • Problematic: You have some of users within a VTX "Connect PABX" that wish to use Teams ( keeping their number )
  • Information: Teams can be completely embedded within a VTX VPBX with the VTX Teams Virtual service. For PBX, integration is different.
  • Solution: There are 2 possible solutions

Solution 1: Move some numbers to Teams

  1. (VTX) Subscribe to a VTX Teams Virtual or VTX Teams Connect depending on your needs
  2. (Teams) Prepare your user in Teams with the desired number
  3. (VTX) Ask VTX to move the number from the PBX to Teams
  4. (PBX setup) Remove the number from PBX setup
  5. (PBX setup) Redirect internal number to full number. So if an internal user calls the short number or the full number of the colleague, it will go out from the PBX->VTX->Teams


Solution 2: Use Teams in parallel of existing phones behind the PBX: Incoming calls ringing on PBX + Teams, outgoing calls possible from PBX + Teams

  1. (VTX) Subscribe to a VTX Teams Virtual or VTX Teams Connect depending on your needs
  2. (Teams) Prepare your user in Teams with another VTX number ( new number provided by VTX that won't be shown when calling out )
  3. (Teams) Follow FAQ:Teams#CLIP_:_Number_Display_-_I_wish_to_display_a_different_number_than_my_direct_line_for_my_outgoing_calls to have this Teams account displaying the PBX number
  4. (PBX setup) Setup the PBX to have a parallel ringing between the user account on the PBX and the VTX Teams account

Features[edit | edit source]

Main Teams Features not related to VTX[edit | edit source]

The idea of this wiki is not to document how Teams App is working, but this Microsoft is doing a great job. So if you have questions about specific features in Teams ( not related to VTX), please have a look at their documentation


Teams GAB (Global Address Book) Directory Missing[edit | edit source]

  • Status: As incredible as it sounds, It doesn't seems possible to enable a Global Address Book directory for several Teams users
  • Actions: We have tried it and with Ops Team and even with an Azure Active Directory Premium license, it is not possible to create a global directory
  • Information
    • The feature request for a GAB ( Global Address Book ) was visible in E365 Roadmap in 2020 but was deleted afterwards
    • With a Team Virtual, it would be possible to have incoming call reverse lookup ( and only incoming call reverse lookup ) ! But not with a Connect Teams, info added in VoIP:VTX_Teams_Virtual#VTX_Teams_Virtual_value_added_features
    • Some external paying tools seems to allow to sync an external directory with each individual Teams Directory, but it gets tricky
  • References:


  • Conclusion:
    • VTX is not responsible for the lack of this missing features in Teams, and indeed this one doesn't seem to be possible
    • Some tweaks might be possible with full Office 365 integration but we haven't tested it



Delegate : Share a phone line with a delegate[edit | edit source]

  1. For "Teams Connect" users, you can already use this feature, it is allowed on VTX side, cf https://support.microsoft.com/en-us/office/share-a-phone-line-with-a-delegate-16307929-a51f-43fc-8323-3b1bf115e5a8
  2. for "Teams Virtual" users, please contact VTX support with this URL as reference to have VTX enabling this feature. ( VTX internal reference for automation is "Redmine #93076" )


Use Teams to follow "tel:" or "callto:" URL[edit | edit source]

  • Information: Once you have selected a default app to perform outgoing call, you will need to manually change it to use another Application to handle the tel: uri
  • Problematic: You wish to setup your PC to use Teams app for tel: and callto: URLs to directly call numbers from web browsers
  • Solution ( Windows 10 ) : Change the default app for tel uri
  1. Click on the link below to verify id your system is already setup to use Teams for tel: and callto: URLs, if not continue to follow the steps
  2. Go in Control Panel / Programs / Default Programs and click the "Set your default programs"
  3. Go in the bottom of the menu to "Set Defaults by app" and click on Teams
  4. Click the "Choose a default" and select Teams / Manage
  5. For URL:callto and URL:tel select "Teams"
  • Example: You can use the links below to perform tests
    • +41225117902 : VTX Echo test number without any link except if your browser is able to detect this as a number
    • tel:+41225117902: VTX Echo test number with tel: URI syntax
    • callto:+41225117902: VTX Echo test number with callto: URI syntax
Windows 10 - Default Program - Change tel uri for Teams
Windows 10 - File type and protocol associations - Change tel uri for TEams

Frequent Errors[edit | edit source]

New-CsOnlineVoiceRoutingPolicy - Cannot find specified Online PSTN usage[edit | edit source]

  • Problem: When we run the script to create the call routing, you might get a red error that New-CsOnlineVoiceRoutingPolicy is not working
  • Symptoms: When running the script to create the call routing, you might get an error "Cannot find specified Online PSTN usage"
  • Possible Explanation:
    • You forgot to create the temporary User "enableteams"
    • MS Teams platform is getting some delay and between the time we create the Online PSTN usage and the time we use it in Online Voice Routing Policy, we need to wait for Teams platform to get up to date
  • Solution:
  1. Verify that you did create the "enableteam" user, cf VoIP:VTX Teams Virtual#Create_a_temporarily_user_in_the_.3Cservicenumber.3E.teams.ipvoip.ch_domain
  2. Wait up to 4h and try again to use the script again


As you can see after some time, the same command did work

AD Sync Problem[edit | edit source]

What are the numbers defined and used in Teams ?[edit | edit source]

  • Information: Teams is using the LineURI and OnPremLineURI parameters to define the number to be used by Teams ( cf below )
  • Problem: If you do have an AD sync with Azure Cloud that is overwriting these parameter, Teams telephony calls towards external numbers will stop working
  • Symptoms: You are getting a "404 Not found" error on incoming calls
  • Solution: Please follow the procedure below
  1. Use VoIP:VTX Teams Virtual#Verify_User_Setup to verify that number currently set for the Teams user
  2. Make sure your AD sync is not overwritten these fields or make sure it does set the same numbers
  3. Re-assign the number in Teams using VoIP:VTX Teams Virtual#Number_Mapping_:_Assign_numbers_to_Microsoft_accounts
