Telefónica Germany Migrates 4G/5G Voice Services for First 100 Thousand Customers to Mavenir's Cloud-Native IMS Technology
Telefónica Germany has successfully migrated voice services for its first 100,000 customers to Mavenir's cloud-native IP Multimedia Subsystem (IMS) technology running on Amazon Web Services. This migration represents a significant milestone in the operator's transition from legacy voice infrastructure to modern cloud-based voice services for both 4G and 5G networks. The deployment marks the beginning of Telefónica Germany's broader strategy to modernize its voice infrastructure by moving both fixed and mobile customer bases to Mavenir's web-scale IMS solution. This cloud-native approach enables the operator to leverage the scalability and flexibility of AWS infrastructure while providing Voice over LTE (VoLTE) and Voice over New Radio (VoNR) services to its subscribers.
Why It Matters
This migration demonstrates the telecommunications industry's continued shift toward cloud-native network functions, particularly for critical voice services. The successful deployment of cloud-native IMS on public cloud infrastructure like AWS represents a significant technical achievement, as voice services require extremely low latency and high reliability. For the broader telecom industry, this validates the viability of running core network functions in public cloud environments and could accelerate similar migrations by other operators seeking to reduce infrastructure costs and improve service agility.
