Telkom SA builds Africa's Top VoLTE network based on Single Voice Core

As the global deployment of 4G and 5G becomes more and more widespread, how to realize seamless transition from last-generation to next-generation telecom technologies has become an urgent problem for all operators. "We had a successful introduction of VoLTE and subscriber migration from 2G/3G to LTE and VoLTE, and would like to shutdown 2G/3G services to make the spectrum available for newer technologies. The legacy services do not allow us to immediately turn off 2G/ 3G." said Brite Devassy, Executive of Technology & Strategy, Telkom SA. On October 13, 2021, at the 5G Core Summit in Dubai, Brite Devassy gave a wonderful speech about the evolution of Telkom's voice network.

Telkom has always been committed to leveraging cutting-edge technologies of telecom industry to roll out new services and optimize networks. Telkom chose Huawei's Single Voice Core solution to develop VoLTE. This initiative enables 2G/3G/4G/5G/Fixed users to access the same IMS network, solving the operation & maintenance and investment problems caused by the coexistence of multi-generation networks. The simplified network enables Telkom to pack lightly and focus on 4G/5G. "The timing of Huawei SVC product is perfect for us." said Brite Devassy.

The achievement of VoLTE has showcased Telkom's capabilities to utilize innovative solutions. Telkom will continue to enable more and more users to enjoy high-quality VoLTE calls while surfing the Internet at high speed.
