Voice over New Radio (VoNR) Testing

Automated E2E active testing to safeguard 5G Voice Services


VoNR (Voice over New Radio), also known as Voice over 5G (Vo5G), enables speech services over 5G networks and will replace traditional voice services (such as circuit-switched and VoLTE) due to its efficiency and reliability.

VoNR uses 5G SA technology similar to data transmission and provides high-quality voice services with low latency. While VoNR has many similarities to VoLTE, such as utilizing the IMS with SIP-based Signaling for Registration and Call Setup procedures as well as encoding voice packets into RTP protocol, it differs in terms of 5G RAN features, a flow-based QoS and Always-On PDU.
