sync.blue® ermöglicht den Mitarbeitenden von HYDAC immer in Kontakt zu bleiben. Egal wann und wo! Case Study aus dem Bereich Hydraulik und Engineeringlösungen.

The Fürst Group is a Germany-wide staffing services provider specializing in facility management, general staff and security. The company needed a solution to reliably synchronize contacts from the Global Address List (GAL) to company cell phones while simultaneously making them available in Microsoft Teams, so that the IT hotline could clearly and quickly identify callers within the IT-support queues. Using sync.blue®, the Fürst Group has solved both requirements using a single, centralized platform.

Fürst Gruppe


The Fürst Group is a service provider operating throughout Germany, specializing in facility management, security, cleaning, and staffing services. The group relies on modern IT and communication solutions to streamline internal processes and provide optimal support to its employees.


Missing Caller ID in the IT-Hotline


Internal calls from employees often appeared as unknown numbers within the IT hotline. The reason: Microsoft Teams could not access contact information in the Microsoft Global Address List (GAL).

This meant that IT experts had to manually look up every number from the call queue in the directory. This delayed callbacks and made coordination unnecessarily time-consuming. At the same time, contacts needed to be automatically and reliably available on employees’ company cell phones - so the Fürst Group needed a solution that could consolidate and synchronize contact data from GAL, Teams, and mobile devices within a single platform.


One platform for all contacts


With sync.blue®, the Fürst Group builds its contact management and synchronization on a platform that covers both the synchronization of contacts from the GAL to company mobile phones as well as the distribution of contacts into Microsoft Teams.


Internal contacts are thus automatically available, up-to-date, and require no manual updating – whether on mobile devices or via the IT hotline. This ensures reliable caller ID, faster callbacks, and significantly more efficient team workflows.


"Once contacts are consistently available everywhere, clear workflows emerge. That’s exactly what sync.blue® provides to the Fürst Group—every day.

Hendrik Janssen, Key Account Manager at sync.blue®


Quick setup


The implementation of sync.blue® went smoothly and without any technical issues. All synchronizations were configured quickly, and any questions raised with sync.blue® Support during the process were answered without any delays.


"We were looking for an all-in-one solution that covers both mobile devices and teams. That's what we found in sync.blue®."

Markus Berger, System‑ and Network Administrator at Fürst Gruppe


Added value throughout the workday


Thanks to sync.blue®, the IT help desk can now clearly identify internal callers - eliminating the need for manual number lookups. This saves the IT team a significant amount of time every day. In addition, contact information is always available on company cell phones, improving mobile accessibility for employees and streamlining daily work processes throughout the company.


Future-proof with sync.blue®


Active contact synchronization keeps data up to date at all times and prevents outdated entries. The IT department is very satisfied with the solution. As Teams calling continues to expand, sync.blue® will also become relevant in other departments in the future, particularly those that use call queues.
