Example screenshot in Azure Portal – API name – Permission – Admin consent

Example screenshot in Azure Portal – API Name – Permission – User consent


In the Azure Portal, there are settings for the company indicating that User consent is not possible at all and can only be made by the administrator:

In this case, User consent in the UCServer management cannot be performed with any user account, but must be based on the assigned rules for Enterprise Apps in the Azure Portal.

For this reason, and if the same Administrator account is used for User consent and Admin consent, the granted permissions are displayed in the "Admin consent" table in the Azure Portal. The table for the User consent remains empty.

Password changes/expired password

Please note that in case of password changes or for an expired password for the administrator or user account used for Admin or User Consent, the authorization must be reissued in UCServer to ensure functionality.

For example, for passwords that are about to expire, an organizational measure can be taken to reassign the password on the previous working day and renew the admin or user consent in the same process step. In this way, downtime can be reduced to a minimum.


Permissions  API Permissions  Consent

In order for the UCServer to be allowed to read team users' presences, a so-called "User consent" is required. This can be done centrally from the point of view of a user who has carried out the "User consent" in the UCServer administration.

In order for the UCServer to be able to set the presence of the teams users, a so-called "Admin consent" is necessary. This can be done either via the Azure portal or via the "Admin consent" button in the UCServer administration.

It is nevertheless advisable to view the permissions of the enterprise application "estos ProCall Integration in Teams" in the Azure Portal. Access can also be removed again via this.

You can see in the UCServer management if the authorization was successful.

UCServer management

Once the required permissions are set, integration with Microsoft Teams can be enabled globally, per group (services) or for individual users (services).

Note that the users in UCServer management and Azure Active Directory must match in username or UPN (user principal name).

From ProCall version 7.3.5 and above, it is possible to create a file in which users are optionally assigned if there is no unique match. Copy this file to the "ExternalServiceProvider" directory in the UCServer installation folder. This list is loaded after activating the Teams integration in the UCServer management.

File name: usermatching.csv

Content (comma separated): Azure AD username,UCServer username

In the example, user Max Mustermann has the UPN "max.mustermann@domain.local" in the UCServer user management. In Azure AD, he has the UPN "". Further entries can follow in additional lines.

Example usermatching.csv,max.mustermann@domain.local,lena.frisch@domain.local

Please note that user names in the CSV file are case-sensitive, otherwise they cannot be matched.

Web proxy support

Available from ProCall Enterprise 8.0.1 or 7.6.1.

If a web proxy in the company controls internet traffic, it is usually configured via the proxy settings of the Windows operating system (Control panel → Internet options). However, these settings are stored in the user context, which is why the UCServer service running in the context of the local system account cannot access these settings (the UCServer administrator is running as a user, which is why the proxy settings work here).

This means that you can only tell the UCServer service the settings if they have been saved in the LocalSystem context. You can find instructions on the internet.

You can also specify a proxy for Microsoft Teams presence integration via configuration:

  • Stopping the UCServer service
  • Editing the file "msteams.cfg" in the config folder of the UCServer installation directory
    • Add the line (note json format)
    • "u8sProxyAddress" :  "PROXY-Server IP:PORT" (z.B. "u8sProxyAddress" : "")
    • Save
  • Restart UCServer service
  • In the UCServer administration it is then also visible if a proxy has been configured for the teams connection
  • UCServer Verwaltung ist dann auch sichtbar, wenn ein Proxy für die Teams Anbindung konfiguriert wurde.
