The milestone represents a significant step in the telecom operator's transition from legacy circuit-switched voice infrastructure to modern all-IP communications for both 4G and 5G networks. The migration encompasses both fixed and mobile subscriber bases, moving them to Mavenir's web-scale IMS solution hosted in AWS cloud infrastructure. This deployment marks a key achievement in Telefónica Germany's broader network modernization strategy, demonstrating the practical implementation of cloud-native telecommunications infrastructure at commercial scale. The successful migration of the initial customer cohort validates the technical approach and paves the way for expanding the cloud-based voice services to the operator's entire subscriber base.
