VoNR/VoLTE Solutions
Assuring voice quality so your customers never miss a word.
Learn more about our VoNR/VoLTE solutions
VoNR and VoLTE are advanced technologies that enable high-quality voice calls over modern mobile data networks. VoNR, on the other hand, is the 5G evolution of VoLTE. It enables native voice calls over the 5G Standalone (SA) core network, without relying on 4G fallback. This delivers even lower latency, improved call quality, and a more seamless user experience as operators transition to fully 5G-based networks. In short, VoNR represents the next step in voice evolution, building on VoLTE’s foundation but optimized for 5G’s speed, efficiency, and end-to-end architecture.
VoLTE allows voice services to run over a 4G LTE network, using the same data infrastructure that delivers internet and multimedia services. It provides faster call setup times, higher audio quality (HD voice), and supports simultaneous voice and data connections than previous mobile network generations. Voice remains one of the most used and sensitive services. Poor voice quality or dropped calls directly impact customer satisfaction. Service assurance enables customer-centric insights, linking network KPIs to actual user experience, so operators can take proactive care actions and protect brand perception.

How Can RADCOM Help?
RADCOM’s intelligent assurance for VoNR/VoLTE offers a comprehensive, end-to-end solution that intelligently monitors the customer experience across mobile networks. The solution provides end-to-end (from RAN to core) analysis to help operators deliver a superior customer experience across all their voice service offerings. Offering complete visibility into VoLTE and VoNR services, pinpointing real-time issues, rectifying service quality problems, and monitoring the entire call flow from the RAN to core. The solution addresses specific problems that operators face when assuring VoNR and VoLTE services, including detecting and resolving one-way audio issues, setup delays, mute calls, mobility issues, circuit-switch fallback (CSFB) issues, and user device issues. From engineering tools to cell analysis and voice service dashboards for the NOC/SOC, we enable you to keep a finger on the voice service pulse.
On-Demand Probing
With the ability to deploy on-demand probes, RADCOM enables operators to dynamically instantiate, scale, move, and retire probe functions precisely when and where they’re needed, without pre-provisioning. For example, if a VIP customer reports issues with VoNR services, operators can instantly deploy targeted monitoring to capture full RTP data for 10 minutes, automatically decode, correlate, and troubleshoot the session in real time. The platform generates KPIs from the RAN and core datasets, correlating RAN and core signaling at a 10-second sub-session interval per subscriber. It creates KPIs specific to network entities (e.g., cells, sites, bands) and classifies these entities, aggregating the data into geospatial bins. The analytics are presented in integrated dashboards and automated workflows to support accelerated optimization of the VoNR/VoLTE network.
RADCOM VoNR/VoLTE Solution Portfolio
VoNR/VoLTE Network Optimization
RADCOM VoNR/VoLTE Network Optimization enables operators to proactively troubleshoot their VoNR/VoLTE network using real-time insights that accelerate root cause analysis, improves customer satisfaction and drives service quality. The solution performs end-to-end cross-domain correlation and root cause analysis across RAN, backhaul, core, IMS, and the VoNR application server. With the ability to seamlessly drill down from a macro network overview to detailed packet and session-level insights, operators can efficiently identify issues, optimize performance, and enhance service quality from core to RAN.
VoNR/VoLTE Service Analysis
RADCOM VoNR/VoLTE Service Analysis empowers operators with the ability to deliver top-quality HD voice services. By continuously monitoring and analyzing quality of service metrics, operators gain the visibility needed to ensure consistent service delivery, quickly detect degradations, and maintain optimal network efficiency. In a competitive market where voice quality defines success, RADCOM’s customer-centric approach provides the foundation for dependable, high-speed voice services that exceed customer expectations and strengthens operator differentiation.
VoNR/VoLTE User Analytics
RADCOM VoNR/VoLTE User Analysis empowers operators to elevate customer experience by providing end-to-end visibility into real user performance. The solution generates a Customer Experience Index (CEI) for each service, across both voice and data, offering a granular view of how subscribers experience voice and data services in real time.
This allows operators to proactively identify issues, deliver superior service quality and drives customer satisfaction and loyalty. By enabling visualization of the entire voice experience, RADCOM helps operators break down silos creating a unified approach.
