A Sip of the Cloud: DIWISA Embraces Microsoft Teams Voice

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.

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.

DIWISA is savouring the cloud sip by sip – and making calls with Microsoft Teams Voice.
