At the start of the project, Blumer Lehmann in Switzerland used a carrier SIP (Session Initiation Protocol) trunk to which the old classic telephone system was connected. The employees still used traditional landline telephones and wireless handsets. In the branch offices, the company used different proprietary telephony systems from various national telephone companies.

The aim of the project was to simplify communication and telephony between the locations and to replace the old telephone system. This included the introduction of a standardised, future-oriented Microsoft Teams telephony solution to ensure more efficient and better integrated communication.

In addition, the company aims to standardise the various national telephony systems in order to simplify user management and administration and optimise communication processes throughout the organisation.

The project was carried out in several stages in close collaboration to achieve the goal of a simplified and modernised communication infrastructure:

• Replacement of conventional telephone systems: the existing telephone systems were replaced by the modern Microsoft Teams telephony solution.

• Individual employee accounts: Each employee was given a personal Microsoft Teams account, enabling direct communication between employees. This included user training and the introduction of mobile devices via the data network in the system, which increased communication flexibility and accessibility.

• International implementation: The telephony solution with Microsoft Teams was gradually standardised across all locations. This significantly improved communication between the various national and international offices.

The project ran smoothly from a technical perspective, but there were a few organisational hurdles to overcome. For example, the switch from wireless telephones, or more precisely DECT telephones, in production to user-orientated Microsoft Teams telephony. Smartphones were introduced as a solution, which ensure mobile telephony with the Microsoft Teams app. The employees were trained in groups and supported in setting up the new end devices.

The switch to Microsoft Teams telephony brought the following results thanks to good cooperation:

• More efficient IT infrastructure: The implementation of cloud solutions led to a modernised and more powerful IT infrastructure. As a result, communication is also maintained and serviced using the same IT resources.

• Technical changeover: A smooth migration to an advanced cloud telephony platform was realised, including modern connections to the public telephone network. The old telephone network was dismantled.

• Improved customer service and communication: Microsoft Teams provides employees with a standardised communication solution. The transition to cloud-based telephony has also increased communication efficiency at all locations.

• Successful introduction and ongoing support: Internal training courses made it easier for employees to switch to the enhanced communication solution. In addition, support was and continues to be provided for setting up and using the new technologies.

The solutions offered were precisely tailored to the specific needs and requirements of Blumer Lehmann. The awards as Microsoft Solution Partner Modern Work with the specialisations "Adaption and Change Management", "Calling for Microsoft Teams" and "Meetings and Meeting Rooms for Microsoft Teams" were clearly reflected in the expertise of the project.
