Reliance Jio rolls out VoNR on indigenous 5G Core nationwide

Reliance Jio has rolled out Voice over New Radio (VoNR) services throughout India by enabling next-generation voice calling on its fully indigenous 5G Standalone (SA) core network. The service made by Aayush Bhatnagar, Senior Vice President at Jio leverages the company's in-house 5G SA Core and IMS-enhanced VoNR Core. The launch coincides with Jio's ninth anniversary on September 5.

"Jio has successfully enabled Voice over New Radio (VoNR) across India, leveraging its fully indigenous 5G Standalone (SA) Core and Jio’s own IMS-enhanced VoNR Core. This pan-India rollout establishes Jio’s end-to-end VoNR capability on its homegrown technology stack, enabling ultra-low latency, high-definition voice services natively on 5G," Bhatnagar said in a LinkedIn post.

Bhatnagar added, "Jio has pioneered the world's largest-scale VoNR deployment — powered entirely by its indigenous 5G SA Core and IMS VoNR Core with this milestone." “With this milestone, Jio reinforces its commitment to: Building a fully indigenous technology stack — from 5G radios to 5G SA Core and VoNR-enabled IMS."

Bhatnagar said that this will also drive sovereign capability in advanced telecom systems, with a global appeal, and deliver a future-ready digital experience for every Indian.

VoNR enables high-definition, low-latency voice calls directly on the 5G SA network, eliminating the need to fall back on 4G networks. The technology is expected to deliver faster call setup, fewer call drops, and lower battery consumption, significantly enhancing the user experience.
