Telekom completes transformation to cloud-based voice telephony

  • The foundation for infrastructure cloudification is now in place.
  • Telekom successfully migrated more than 17 million voice subscribers.
  • Through cloudification and automation, new functionalities in the voice network can be introduced with the click of a button.
Deutsche Telekom has successfully transitioned its IP-based voice telephony platform to the cloud.

Deutsche Telekom has successfully transitioned its IP-based voice telephony platform to the cloud. Landline connections are now centrally controlled from cloud data centers in Germany. Over seventeen million customer connections have been migrated. Billions of voice minutes are now handled entirely through the NIMS platform (NIMS: Next Generation IP Multimedia Subsystem) with around 100 interconnect partners.

Thanks to disaggregation, services can be provided through an optimized solution portfolio of software modules from a wide ecosystem of industry partners. The near-complete automation of the Telco Cloud provides a more efficient process, leading to significantly more flexibility and speed in the introduction of new service features and capacity expansion.

"This project is a game changer in the industry," says Abdu Mudesir, Chief Technology Officer of Deutsche Telekom Deutschland. "It is the result of excellent cooperation with partners such as Juniper Networks, Mavenir, Microsoft, HPE, Red Hat, and Lenovo. Our common goal in this innovation project has always been to set a benchmark for excellence in the industry, for our customers. The success has spread, many network operators are now asking us specifically how we managed to achieve this."

“The cloud isn’t just a technology, but rather an entirely new operating model that can yield tremendous agility, cost efficiencies and better user experiences. I am so proud that Juniper was able to play a role in bringing Deutsche Telekom’s visionary strategy for NIMS to life and even more thrilled to see this project, which I consider a blueprint for the rest of the telecom industry, now complete,” says Rami Rahim, CEO – Juniper Networks.

“With NIMS, Deutsche Telekom has leveraged the benefits of cloud native network functions, hyper scaler technology and extreme automation to deliver mission critical carrier grade performance; it’s a huge step forward in the Telecommunications industry," says Yousef Khalidi CVP, Azure for Operators – Microsoft. 

“Telekom´s vision was unique because it was not just a pure technology play. Its goal to change the old development paradigms, driving automation and interoperability into the very fabric of the Telco Cloud architecture.  The NIMS platform offers a transformative lifecycle automation for all telco cloud and payload components and Mavenir is proud to be part of the multi-vendor ecosystem delivering this innovation,” says Bejoy Pankajakshan, EVP & Chief Technology and Strategy Officer of Mavenir.

“The platform is a key building block for ´Zero Touch operations´ where manual intervention and operations to handle network management and configuration are reduced in favor of a more advanced, software-based solution,” says David Stark, VP & GM, Telco Solutions - HPE.

Telekom has already established follow-up projects to consistently implement the successful model of cloudification, disaggregation, and complete automation in other voice applications, 5G Core and the access networks.
