Voice over Wi-Fi (VoWiFi) is a technology that enables voice communication using a wireless internet connection rather than the mobile operator’s radio access network. First deployed in 2014, it’s particularly useful in areas with weak cellular coverage.

The ePDG is a network element designed for secure access and interworking between 3GPP networks (LTE/5G core) and non-3GPP networks (Wi-Fi). It acts as a security gateway, creating a secure connection from untrusted networks to the mobile core network.

Telecom networks are transitioning from traditional, hardware-based IMS deployments to cloud-native IMS architectures that leverage microservices and are orchestrated using Kubernetes. While this evolution enables greater scalability, resilience and conforms to cloud native principles, it may increase operational complexity. To manage these dynamic environments efficiently, automation has become a critical component of IMS operations as well as the cloud platform.
