Case Study: Bertelsmann transforms digital collaboration with Colt's SIP Trunking Services

Bertelsmann routes 10,000 parallel calls with Colt SIP Trunking

Bertelsmann, a global media, services, and education company, faced the challenge of modernizing its telephony from the outdated ISDN standard to Voice over IP. They sought to create a central, flexible voice infrastructure to serve their diverse business units. Colt Technology Services provided a solution with its SIP Trunking services.

Colt implemented a geo-redundant SIP Trunking solution, enabling high-quality parallel call transmission and connecting multiple German sites. This solution formed the basis for Bertelsmann’s Unified Communications, integrating Microsoft Teams with the public phone network. Colt migrated over 800 phone numbers, resulting in more efficient, digital collaboration across the group and positioning Bertelsmann well for future requirements.
