The spirits specialist DIWISA discovers cloud telephony.
How the Swiss spirits specialist replaced its traditional phone system with Microsoft Teams Voice within half a year, gaining productivity and flexibility in the process.
DIWISA AG transitions its telephony to Microsoft Teams Voice with Baggenstos. The Swiss spirits producer is gradually embracing the cloud – one sip at a time. In partnership with Baggenstos, the company replaced its traditional phone system with Microsoft Teams Voice.
Within six months, Baggenstos transitioned DIWISA from a conventional SIP trunk setup with 30 voice channels on a Mitel PBX and a public main number to a fully cloud-based solution.
The result? A highly flexible telephony system aligned with the company’s evolving business model and staffing needs. Thanks to thorough preparation, the changeover went smoothly not only on the technical front. Employees quickly embraced the new solution and noticed immediate productivity benefits. By integrating Teams’ communication and collaboration workflows, both internal and external processes became more streamlined.

Facts & Figures
Starting Point and Objectives
DIWISA is taking a gradual approach to cloud transformation, aiming to phase out on-premise infrastructure. One major milestone was the replacement of the legacy phone system – a project led by Baggenstos. Beyond the technical migration, the focus was also on getting employees on board.
Key Figures
- 100 employees in total
- 57 users with direct phone numbers
The Solution and Its Rollout
The project began with several weeks of analysing communication needs and patterns – time well spent. The Teams Voice setup worked right away, and employees quickly felt at ease using the new clients on both desktop and mobile devices.
With all communication now unified in a single app, Microsoft Teams Voice offers intelligent, flexible, and easy-to-manage telephony.
Challenges
As with any major change, some employees were initially hesitant. However, thanks to clear guidance from Baggenstos and hands-on support from DIWISA’s in-house IT lead, everyone received personalised training. A particular challenge was onboarding production staff, who don’t regularly work at a computer.
Results
Cloud-based telephony in record time: the move to Teams Voice quickly delivered productivity gains. Employees are no longer tied to desk phones or wall-mounted handsets. Instead, they benefit from the full range of modern communication tools – all in one app.
IT can now scale and adapt telephony with ease, adding customer contact points for new markets without hassle. Most importantly, DIWISA has replaced local infrastructure investments with predictable cloud-based costs.
After introducing Microsoft 365 a few years ago, moving our traditional phone system to Microsoft Teams Voice was the logical next step: thanks to the careful approach of the Baggenstos team, it went off without a hitch and has improved our communication at predictable costs.
