Case Study: Subsea 7 achieves over 50% calling cost savings and streamlined global communications with Hewlett Packard Enterprise's Microsoft Skype for Business solution

Subsea 7 Reduces Costs by Migrating Worldwide To Microsoft Skype for Business

Subsea 7, a global leader in seabed-to-surface engineering, faced high telecommunications costs, fragmented telephony (45 Cisco Call Managers), a single datacenter with no enterprise voice or disaster recovery, and legacy contracts with multiple providers. Hewlett Packard Enterprise (HPE), using HPE Technology Consulting Services and HPE digital collaboration solutions, was engaged to migrate the company worldwide to Microsoft Skype for Business and design a unified communications and SIP trunking roadmap.

Hewlett Packard Enterprise implemented Skype for Business across five continents, consolidated 45 Call Managers into four Skype pools, built three additional datacenters (Houston, Singapore, Aberdeen) with disaster recovery, deployed HPE ProLiant BL460c Gen9 blades, and rolled out SIP trunking and localized bandwidth management. The HPE solution delivered estimated first‑year calling savings of over 50%, an 80% reduction in conferencing costs, simplified management and increased productivity, and improved reliability and failover across Subsea 7’s global operations.
