Telefónica Germany migrates 4G/5G voice services for first 100,000 customers to Mavenir's cloud-native IMS technology
Telefónica Germany has reached a significant milestone in its network modernization efforts by successfully migrating voice services for its first 100,000 customers to Mavenir's cloud-native IP Multimedia Subsystem (IMS) technology running on Amazon Web Services. The migration encompasses both 4G and 5G voice services, representing a major step in the operator's transition away from legacy circuit-switched voice infrastructure to modern all-IP communications. The deployment utilizes Mavenir's Web-Scale IMS solution, which is designed to handle massive subscriber volumes while providing the scalability and flexibility benefits of cloud-native architecture. This implementation allows Telefónica Germany to consolidate voice services for both its fixed-line and mobile customer base onto a single, modern platform that can dynamically scale resources based on demand and deliver advanced voice services across its network infrastructure.
Why It Matters
This migration represents a significant shift in how major European carriers are approaching voice service delivery, moving from traditional telecom infrastructure to cloud-native solutions that can scale more efficiently and reduce operational costs. The successful deployment of 100,000 subscribers on AWS-hosted IMS infrastructure demonstrates the maturity of cloud-based telecom solutions and could accelerate similar migrations across the industry. For the broader telecom sector, this validates the viability of running mission-critical voice services on public cloud infrastructure, potentially reshaping how operators approach network architecture and opening new opportunities for cloud providers in the telecommunications market.
