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#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
(PBX setup) Setup the PBX to have a parallel ringing between the user account on the PBX and the VTX Teams account

License Management[edit | edit source]

Microsoft Teams Shared Devices - Not working anymore on Web + Desktop Client - "You don't have the required permissions to access this org"[edit | edit source]

Symptoms: You are using a "Teams Shared Devices" license and are trying to connect to Teams v2 Client and you get an error "You don't have the required permissions to access this org"
Explanation: The "Teams Shared Devices" is now not working anymore on Desktop and Web Client
Solution: Either upgrade to a more expensive license or only use the Mobile Client
Additional Information: https://learn.microsoft.com/en-us/microsoftteams/teams-add-on-licensing/teams-shared-device-license

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

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:
- 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 FAQ:Teams#Create_a_temporarily_user_in_the_.3Cservicenumber.3E.teams.ipvoip.ch_domain
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

Outgoing Call[edit | edit source]

I cannot call a colleague not using Teams yet / not using Teams anymore dialing his +e164 number on this VTX Teams service[edit | edit source]

Information: Once you have assigned an +e164 number to a Teams user using FAQ:Teams#Number_Mapping_:_Assign_numbers_to_Microsoft_accounts, if you dial this number from Teams, it will be intercepted by Teams as a local call and will ring only on the Teams account of your coworker
Symptoms: I am calling a colleague with Teams dialing his +e164 number and it is not working because this colleague is not using Teams on this service anymore / yet
Solution: Use one of the 2 solution below to have you call towards your colleague +e164 number going out to VTX to be handled as a normal call

Use FAQ:Teams#Number_Mapping_:_Assign_numbers_to_Microsoft_accounts to remove the number to from the Teams user

Teams - Caller ID Policies - Cannot define a number

CLIP : Number Display - I wish to display a different number than my direct line for my outgoing calls[edit | edit source]

Problematic: For outgoing calls, you wish to display a number that is different than your direct line number
Information: By default, you will be allowed to display any number belonging to your trunk ( visible in Kiosk ). If you try to display a number that doesn't belong to your trunk, the system will fallback to your direct line
Solutions: 2 solutions are possible, one from Teams Admin Center, and another one from VTX Kiosk
Solution from Teams:

Read https://learn.microsoft.com/en-us/microsoftteams/caller-id-policies : You can create Caller-ID policy to have some users displaying some resources account numbers (Auto Attendant or Call Queue)
Go in https://admin.teams.microsoft.com/policies/callinglineid and create a new Caller-ID policy by setting the number that you wish to display
Go in https://admin.teams.microsoft.com/users and set the new caller-ID policy to the users that need to use it
Wait some minutes
Now these users will display the service number for outgoing calls

Solution from VTX Kiosk:

Display my company main number : Connect to your Kiosk https://kiosk.vtx.ch/VoIP/ListNumbers.aspx ( My Services / Telephony / Manager your numbers ) / Edit number / Outgoing calls and change number to be displayed
Display another number belonging to me like my Mobile or a 08x number : Contact VTX to add a "Virtual Number"
Display any number / Forward Caller Number : Contact VTX to enable "Special Arrangement"

Change number to be displayed in Teams Admin Center

Teams Admin Center - Create Caller-ID policy

Teams Admin Center - Assign Caller ID Policy to users

Change number to be displayed in Kiosk

Kiosk - Change number to be displayed

Here is a table explaining what number will be displayed


Number you wish to display (From SIP Header)	Number you wish to Bill (P-Preferred-Identity)	"Special Arrangement" setting in VTX CRM	Option D'affichage in Kiosk (PS: Any number belonging to you could be added by VTX in this list as "Virtual Number")	Number that will be displayed (out From SIP Header)	Real Caller Number (out P-Asserted-Identity)
Your direct line A	Your direct line A	%	Your direct line A	Your direct line A	Your direct line A

An external number like a mobile	Your direct line A	No	N/A	Your direct line A	Your direct line A
An external number like a mobile	Your direct line A	Yes	N/A	An external number like a mobile	Your direct line A

Special Arrangement : I wish to keep the number of the caller being displayed when redirecting call to an external number[edit | edit source]

Problematic: You are redirecting incoming call towards and external number and you wish to keep the number of the caller being displayed on remote destination
Problem: Since you are trying to display a number that doesn't belong to your trunk, it is not allowed and caller id will fallback to your direct line
Solution: Ask VTX to enable the "Special Arrangement" on your trunk, and also ask VTX to add a "+1" to push the project "#2304 - [Kiosk] ConnectPABX - Be Able to Manage Special Arrangement and Number Format from Kiosk Directly"

CLIR : Hide my phone number[edit | edit source]

Problematic: You would like to hide your number when calling out
Information: You could also setup CLIR / "Anonymous Call" from the Kiosk, but please either do it from Teams or from the Kiosk, but not from both in the same time, cf FAQ:Teams#CLIP_:_Number_Display_-_I_wish_to_display_a_different_number_than_my_direct_line_for_my_outgoing_calls
Solution: Follow the solution below

Open your Teams app, go in the Settings menu / Calls tab
Scroll down to the "Caller ID" part

Audio Delay problem[edit | edit source]

Symptoms: You have huge delay over your Teams client that prevent you from having a normal interaction with your interlocutor
Possible Audio Delay source : RDP, Internet Connection, VPN, Team cloud problem
Problematic : You need to perform some tests to identify the source of the problem
Test Call numbers
- "/testcall" ( "/Testanruf" in German ): Teams test call number that can be used to test latency within Teams Cloud. Simply call "/testcall" ( "/Testanruf" in German ) from Teams Call Tab to test latency between your Teams_Client <-> Teams_Cloud
- +41225117902 : VTX Echo Test number will echo back what you are saying allow you to check audio latency between your Teams_Client <-> Teams_Cloud <-> VTX_SBC <-> VTX_Echo_Test_Server
Checks to perform : Here are checks to perform to find the source of the latency

Control Call Quality: Use previous section to check the call Quality of the calls, cf FAQ:Teams#Control_Call_Quality
Teams Service Health Check : Control if Teams is acknowledging a problem FAQ:Teams#Service_Health_-_Get_notified_when_there_is_a_problem_with_MS_Teams
Testcalls: Use testcall numbers above to test if problem comes from Teams cloud or from Teams Cloud <-> VTX Platform interconnection
RDP/VPN : Disable RDP ( use a local Teams client ), disable your VPN and test again
Speedtest : Use https://speed.vtx.ch to test your connection

How to solve the problem

Teams Cloud Problem : Wait that Microsoft solves the problem
