How Nimbus users relate to MS Teams Client roles
Within the MS Teams Client Nimbus will use your existing structures to authenticate any team members as users of Nimbus.
|Role||Installation-related Tasks||Related links|
Tenant Admin is required to execute the Nimbus Installation in your company tenant and
Team Owner is a service administrator in Nimbus and
Team Member is a service user (or agent) in Nimbus and
Team Members are primarily interested in the Usage of Nimbus. Same as Team Owners they access the UI via the following URLs:
|Do not exist in Nimbus.||None - Unauthenticated guest members have no access to Nimbus features.|
Please note that we use the terms "service" and "user" in Nimbus to differentiate towards existing MS channels and its "members" respectively. More info on terms like these can be found in the Nimbus Glossary and Roles and Permissions.
Script execution and impersonation permissions
Nimbus is deployed and (re)configured using Powershell scripts.
- You need Tenant permissions to use Powershell for Nimbus deployment. More infos on Provisioning via Microsoft PowerShell.
- On first script run we highly recommend to start the Powershell session as administrator to ensure that necessary dependencies are installed. Our scripts will retrieve dependencies automatically an install them on your running PC if necessary.
- A re-execution is needed for every service team deployment or service update as the changes need to be pushed to Azure. This process can be automated with Runbook. How to deploy Microsoft Runbook.
External Communication and MS Teams Presence
External access required
TENANT ADMIN You need your tenant to allow external communications with the "luware.com" domain.
The necessary configuration steps are described in the Microsoft Teams Documentation: Manage external Access.
You will also need to disable the "Enhanced Presence Privacy Mode" policy which prevents visibility of the Teams Presence.
The "Enhanced Presence Privacy Mode" is a global configuration which, if enabled, prevents all external organizations from viewing the Teams Presence status of your users via Teams Federation.
If this mode is enabled, Nimbus will see all users as permanently Offline, and thus won't be able to distribute calls to them.
This is a legacy configuration option used in Lync / Skype for Business which is not available anymore in the Microsoft Teams Admin Center and can only be viewed and configured via PowerShell. It is a global setting that always applies to all users and cannot be deactivated or bypassed for individual users.
You can check whether this is enabled in your tenant by running the following PowerShell command:
Get-CsPrivacyConfiguration | Select EnablePrivacyMode
The command will return "True" if the Enhance Presence Privacy Mode is enabled, or "False" (default value) if it is disabled.
To deactivate it, run the following command:
Set-CsPrivacyConfiguration -EnablePrivacyMode $false
Why are these steps necessary? Without being able to read the Teams presence data of your users, Nimbus will consider them as Offline and thus not available for call distribution. They will not be able to receive any inbound calls or place any outbound calls via Nimbus.
Transfer to PSTN limitation
Out of box Nimbus and affiliated addons can only perform PSTN transfers according to Microsoft services licensing & constraints.
Which PSTN license do I need to acquire?
As a tenant administrator you need to acquire and assign the following licenses to the application instance of the respective Nimbus SOURCE service (team) that will act as PSTN transferor:
|Your Setup||Required License|
|Direct Routing||"Microsoft Teams" (App license, available as part of the Microsoft 365 E1 / E3 / E5 and other packages)|
+ "Microsoft Teams Phone Standard" or "Microsoft Teams Phone Resource Account" (recommended)
|Calling Plan||"Microsoft Teams Phone Standard" or "Microsoft Teams Phone Resource Account" (recommended) |
+ "Microsoft Teams Domestic Calling Plan" or "Microsoft Teams Domestic and International Calling Plan"
+ "Communication Credits" (if these aren't already included as part of your plan)
|Operator Connect||"Microsoft Teams Phone Standard" or "Microsoft Teams Phone Resource Account" (recommended)|
Please note that Luware staff cannot make recommendations on which license plan is best suited for your needs. You will need to discuss these needs with your provider, based on your infrastructure and calling plan availability in your country.
How does PSTN licensing affect Service and Call Transfers?
Assuming that Service A has a PSTN license assigned - but further Services don't - the following scenario may unfold:
Note that handling and tracking of running cost for PSTN licenses is outside of Luware support scope.
If you require assistance in extending and/or configuring your Nimbus services for PSTN our support will gladly assist you:
Phone Number configuration
When managing your Phone Numbers for usage of Nimbus services, please note the following:
- If you're using "Direct Routing" (Numbers managed outside of Teams) you can assign any phone number to a Nimbus service.
- If you're using calling plans for Microsoft you can only assign a "Service" number type. "User (subscriber)" type numbers will not work.
These scenarios may work for Nimbus under certain conditions, but are not officially supported by Luware. Note that our support team cannot assist in these cases.
|"Auto Attendant" and "Call Queues" (Teams native)|
Transfer to Teams-native "Auto Attendants" and "Call Queues"
Nimbus does currently not support call-forwarding to either UPN or PSTN numbers of Teams-native "Auto Attendants" and "Call Queues". A transfer attempt will lead to a call abort.
Causes and Workarounds
This is caused by Microsoft Teams limitations and cannot be circumvented by Nimbus.
A possible workaround would be to force the call over your Direct Routing SBC by using an internal dummy number that isn't otherwise associated with any other Teams user or service already. This call would then be routed to your SBC, which can then re-direct it towards the actual number of the Call Queue / Auto Attendant on the Teams side again. As this workaround is dependent on voice infrastructure components outside of Luware's control and support scope, please reach out to your SBC provider or skilled personnel for its implementation.
The above mentioned workaround is not technically feasible if you are using Microsoft Calling Plans or Operator Connect to provision numbers directly through Teams. Forcing an external reroute as a workaround is not possible with these numbers.
|Virtual Desktop Infrastructure (VDI)|
Using "Virtual Desktop Infrastructure" (VDI) with %Productname
Nimbus does not directly support a Virtual Desktop Infrastructures (VDI). Users will see themselves unable to log into neither Nimbus portal or admin URLs.
Causes and Workarounds
Instead of logging into Teams itself, a VDIs redirect the user to a browser window for logging into the Nimbus app. This causes a problem with the login because the token flow doesn't come back to the app within the Teams client. In Nimbus this poses a security risk and is thus considered a non-supported scenario.
→ The only solution on a VDI is to train your users to login to portal.luware.cloud directly, using Nimbus in their browser instead.
Please note that Luware support cannot assist with your VDI configuration. While this scenario may work with an adapted proxy / component configuration on your Tenant, Luware cannot safely guarantee that all customer-side VDI configurations work in this scenario.
|Teams Web Client|
Design Limitation on Microsoft Teams Web Client
The Teams Web Client currently has a known limitation that sends a lot of incorrect status updates especially when refreshing the page in your browser. This has a noticeable impact on how Nimbus handles Agent presence, availability and reporting features.
Causes and Workarounds
Microsoft treats web-based Teams Clients presence status changes differently and with seemingly lower priority. The effects include:
→ Until this is resolved by Microsoft we strongly advise to exclusively use a locally installed Teams Client App for all productive users of your organization.
