New Contact Center Solution for a Modern Workplace with more Scalability and Flexibility

With isolutions, Swissgrid is introducing a new workplace with Microsoft 365 and Teams Telephony to empower employees. Supplemented with a SaaS-based contact center solution, Swissgrid benefits from high scalability, cost overview and flexibility.

Swissgrid is on duty around the clock to ensure that the transmission grid is always stable and secure. Around 650 employees ensure the reliable operation, maintenance and modernization of the Swiss extra-high voltage grid. Swissgrid brings together specialists from a wide range of fields, including engineering and natural sciences, electrical engineering, IT, finance, law and communications. They work together in multidisciplinary teams to actively shape Switzerland›s electricity future. Technological innovations, the far-reaching changes in the energy system and real-time events in grid operation are topics that constantly challenge Swissgrid.

Initial Situation

With the «Modern Hybrid Workplace» project, Swissgrid has renewed the entire workplace of its employees and rolled out a wide range of Microsoft 365 applications. The focus was on improving customer service by introducing a multi-channel contact center solution. In addition to simplified operation for users, automation of special business situations was also crucial. As a further part of the rollout, the previous enterprise telephony and contact center was replaced by Microsoft Teams Enterprise Voice and a contact center solution integrated with Microsoft Teams.

In order to keep the costs for operation and the effort for both support and know-how development manageable and low, Swissgrid opted for a Software as a Service (SaaS) solution in a Managed Service Model. This managed service model (Contact Center as a Service) provides Swissgrid with the desired flexibility and offers the possibility of co-managed management of the Contact Center services by Swissgrid administrators.


In order to be able to implement Swissgrid‘s specific requirements vis-à-vis enterprise telephony, the application was implemented with Luware Nimbus. Luware Nimbus is a SaaS contact center solution that is fully integrated with Microsoft Teams.

Tiered call distribution functionalities (Advanced, Enterprise and Contact Center) and an integration of existing customer applications via Microsoft APIs enable a wide range of solution possibilities. In addition to simple classic call center topics such as transfer and calendar-based call distribution, dynamic and availability-based call distribution, interactive voice response (IVR) systems and skill-based call distribution (Skill based Routing) were also implemented for Swissgrid.

Special requirements such as situation-dependent announcements and special call forwarding could be realized by simple lists, which can also be changed by users who do not have Nimbus administration knowledge.

«At Swissgrid, professional and solution-oriented, but at the same time pragmatic cooperation is important to us. Our partner isolutions was able to convince us and proved these values again and again during the project phase and in operation. It was important to us to have a contact center solution based on our requirements as quickly as possible, and isolutions achieved this very well with the integration of Luware Nimbus into our Teams telephony.
Our requirements were understood quickly, when problems arose they reacted quickly and presented solutions and also on a human level it worked very well right from the start. Accordingly, the project was implemented and completed in a short period of time.
We are looking forward to the further years of cooperation.»
