Microsoft Teams Management[edit | edit source]

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

Signup URL : https://signup.microsoft.com/
Main Admin URL : https://admin.microsoft.com/
- Domain Management URL: https://admin.microsoft.com/Adminportal/Home#/Domains
- User Management URL: https://admin.microsoft.com/Adminportal/Home#/users
- Purchase Services URL: https://admin.microsoft.com/adminportal/home?add=sub&adminportal=1#/catalog

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

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

Connect to https://admin.microsoft.com/Adminportal/Home#/users
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).
Wait a few seconds/minutes/hours for Teams to be enabled on this user https://admin.microsoft.com/AdminPortal/Home#/teamsprovisioning
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
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]

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]

Download https://wiki.vtx.ch/media/VTX_Teams_Create_Routing_Rules.ps1 on your computer ( Right Click on the link / Download )
Open it with Wordpad and use Ctrl-s to save it again ( to inform the system that it is local script )
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]

Open a powershell prompt on your PC
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 )

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]

Download https://wiki.vtx.ch/media/VTX_Teams_Assign_Numbers.ps1 on your computer ( Right Click on the link / Download )
Open it with Wordpad and use Ctrl-s to save it again ( to inform the system that it is local script )
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

FAQ[edit | edit source]

General Questions[edit | edit source]

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

Information: On the VTX wiki, you will find documentation and tips regarding MS Teams Direct Training connectivity towards VTX Telephony Platform, but not related to Teams Global Training
Solution: To get access to Microsoft Teams training, please refer the links below
- Admin trainings for Teams : https://docs.microsoft.com/en-US/microsoftteams/itadmin-readiness
- End User trainings for Teams : https://support.office.com/article/microsoft-teams-video-training-4f108e54-240b-4351-8084-b1089f0d21d7

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]

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

(VTX) Subscribe to a VTX Teams Virtual or VTX Teams Connect depending on your needs
(Teams) Prepare your user in Teams with the desired number
(VTX) Ask VTX to move the number from the PBX to Teams
(PBX setup) Remove the number from PBX setup
(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

(VTX) Subscribe to a VTX Teams Virtual or VTX Teams Connect depending on your needs
(Teams) Prepare your user in Teams with another VTX number ( new number provided by VTX that won't be shown when calling out )
(Teams) Follow FAQ:Teams to have this Teams account displaying the PBX number
(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

Ex: Teams Video Training : https://support.microsoft.com/en-us/office/microsoft-teams-video-training-4f108e54-240b-4351-8084-b1089f0d21d7
Other solution : https://letmegooglethat.com/?q=microsoft+teams+app+write+your+question+here

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
- Some external paying tools seems to allow to sync an external directory with each individual Teams Directory, but it gets tricky
References:
- https://www.msxfaq.de/teams/pbx/teams_rnl.htm
- https://erwinbierens.com/microsoft-teams-using-reverse-number-lookup/

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]

Information: Microsoft Teams allows to delegate management of incoming and/or outgoing calls allowing a colleague/secretary to handle your calls, cf https://support.microsoft.com/en-us/office/share-a-phone-line-with-a-delegate-16307929-a51f-43fc-8323-3b1bf115e5a8
Problematic: You would like to use this feature
Solution: Follow one of the solution below depending on your service

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
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

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
Go in Control Panel / Programs / Default Programs and click the "Set your default programs"
Go in the bottom of the menu to "Set Defaults by app" and click on Teams
Click the "Choose a default" and select Teams / Manage
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:

Verify that you did create the "enableteam" user, cf VoIP:VTX Teams Connect
Wait up to 4h and try again to use the script again

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

Teams Error - Cannot Find Online PSTN Usage - Wait a few hours and try again

Call Queue[edit | edit source]

When hanging up a call, it takes a lot of time before receiving a new call already in the queue[edit | edit source]

Information: Call Queue handling in Teams is completely independent from VTX, if you have a problem with it, if you are able to reproduce the problem by calling the Call Queue name or number directly from Teams itself, then it would confirm problem is 100% Teams related and should be debug on Teams Admin interface or with MS support
Symptoms: You belong to a Call Queue and you were handling a call, you hangup a call but you do not instantly receive calls in the queue
Clue: You did specify a too high value for "Call agent alert time ‎(‎seconds)" in "Agent selection" tab, so it takes ages to have the newly free agent ringing in the queue
Solution: Decrease back the value of "Call agent alert time ‎(‎seconds)" to 15s ( minimum value). Once an agent is free again, it will start ringing back within 15s.
Additional Information: In Call Queue setup, there are 2 parameters that interest us here (Call agent alert time ‎(‎seconds) and Maximum wait time) that are described in https://docs.microsoft.com/en-us/microsoftteams/create-a-phone-system-call-queue

Teams CallQueue - Ring Alert Time too high

Auto-Attendant[edit | edit source]

No ring back tone after redirecting an Auto-Attendant towards an external number[edit | edit source]

Symptoms: You have redirected an AutoAttendant towards an external number and you do not hear any ringtone until the remote phone answer the phone
Explanation: Until Media-Bypass is enabled on VTX SBC with Teams, the incoming call towards Teams and the outgoing call towards the remote phone are 2 independent calls that need to be bridged by Microsoft Teams Cloud, but it is not done correctly for the time being
Solution (not ready):
Workaround: Redirect the auto attendant towards an empty Call-Queue that redirects towards the external number, cf below

cf VoIP:VTX Teams Connect to Create a new Call Queue
1. Set no agents in this queue and Set "Call timeout handling" to 0 min / 0 s
2. Redirect to External number and enter the external number
Redirect your auto-attendant towards this new Call Queue
Call Queue will always send a ring back tone while your remote destination is being called

Teams CallQueue - Redirect to external number

Redirect an Autoattendant to a Teams Audio Conference Room[edit | edit source]

Problematic: You wish to assign one of your number to a Teams Conference Room Number to be able to communicate meetings with a number belonging to you
Problem: Microsoft doesn't allow to use Direct Routing Numbers with Conference Room except for the US DOD. It is only working with the numbers provided by Microsoft Directly
Information:
- On MS documentation, it seems that Direct Routing Audio Conferencing System is only possible for US Department of Defense, cf https://learn.microsoft.com/en-us/microsoftteams/audio-conferencing-with-direct-routing-for-gcch-and-dod
- But in https://learn.microsoft.com/en-us/microsoftteams/audio-conferencing-on-network it is said that we can redirect/map a call to a conference number
Solution: You can "simply" redirect a Teams Auto attendant towards the conference number following solution below

Order a Teams Audio Conferencing license ( ex: It is part of "Office E5")
(Identify the Teams Conferencing Number ) Connect to https://admin.teams.microsoft.com/phone-numbers or use the powershell command Get-CsOnlineDialInConferencingBridge (cf below). Here number is +41432161259
Create an auto attendant with a number belonging to your trunk ( cf sections above )
Redirect this number using auto attendant setup towards this number. So in my example, I am redirecting +41215776420 (number belonging to my company) towards +41432161259 ( MS Conference bridge number )
So now I can communicate on our company number for conference calls

PS H:\> Get-CsOnlineDialInConferencingBridge
