Telefónica Germany Migrates First 100,000 Customers' 4G/5G Voice Services to Mavenir Cloud-Native IMS Technology
Telefónica Germany has successfully migrated its first 100,000 customers' 4G and 5G voice services to Mavenir's cloud-native IP Multimedia Subsystem (IMS) technology running on Amazon Web Services infrastructure. This migration represents a significant milestone in the operator's transition from traditional circuit-switched voice systems to modern cloud-based voice over LTE and 5G implementations. The deployment encompasses both fixed-line and mobile subscriber bases, demonstrating the scalability of Mavenir's carrier-grade IMS solution in handling real-world commercial traffic. This move positions Telefónica Germany among the early adopters of fully cloud-native voice infrastructure, leveraging AWS's cloud platform to deliver next-generation voice services while reducing operational complexity and infrastructure costs associated with legacy voice systems.
Why It Matters
This migration signals a broader industry shift toward cloud-native telecommunications infrastructure, demonstrating that major European operators are confident in deploying business-critical voice services on public cloud platforms. The successful implementation validates the maturity of cloud-native IMS solutions and could accelerate similar migrations across the telecommunications industry, potentially reshaping how carriers architect their core network functions.
