Case Study: Multinational Conglomerate Company achieves unified communications, enhanced collaboration and cost savings with Atos Digital Workplace

Multinational Conglomerate Company - Customer Case Study

Multinational Conglomerate Company faced a fragmented communications estate where employees used Skype for internal calls but relied on traditional PSTN lines for external calls, creating a complicated user experience and higher costs. Seeking a single, compliant global platform that preserved existing telephony investments, the company engaged Atos to modernize its collaboration environment using the Atos Digital Workplace Intelligent Collaboration solution that integrates Skype on Office 365 with the existing telephony core.

Atos rapidly delivered a two-month proof-of-concept and built a platform connecting Skype (Office 365) to the company’s PSTN core using Microsoft Cloud Connector Edition and other telephony technologies, then migrated 11,000 users in five weeks with minimal disruption. The Atos solution now supports 80,000 Office 365 Skype users across 42 countries, enabled measurable call savings, and set the stage to migrate a further 60,000 users in the Americas and Asia‑Pacific in 2019, backed by ongoing maintenance and support.
