Mastering Voice over Wi-Fi (VoWiFi) | Wi-Fi Calling |بالعربي

Voice over Wi-Fi (VoWiFi)—also known as Wi-Fi Calling—is no longer just a niche feature. It's a critical service in modern telecom networks, especially in areas with poor indoor cellular coverage. This course is designed to give you a complete, end-to-end understanding of how Wi-Fi Calling works within IMS-based architectures, how it’s deployed in real operator environments, and how to troubleshoot common issues.

Whether you're a telecom engineer working in Core, IMS, Access, or Radio, or a student aiming to specialize in LTE/IMS/5G technologies, this course will provide the technical depth and practical examples needed to confidently work with VoWiFi services.

We’ll start with the fundamentals of VoWiFi, including the business drivers and benefits. Then, we’ll deep-dive into network elements like the ePDG, AAA server, PGW/UPF, and IMS Core components—explaining their roles in registration, call setup, security (IPSec/EAP-AKA), and bearer establishment.

Through real-world call flows, Wireshark traces, and troubleshooting cases, you’ll learn how to analyze registration failures, call drops, and QoS issues. You'll also explore KPIs, deployment models (like S2b and LBO), and how to optimize for better voice quality and user experience.

By the end of this course, you’ll be able to:

• Understand how VoWiFi integrates with IMS and EPC/5GC.

• Configure and troubleshoot VoWiFi services.

• Analyze message traces and call flows with confidence.

• Apply your knowledge to real operator scenarios.

This course is packed with practical insights, technical clarity, and real-world relevance—a must-have for any telecom professional working in IMS or voice services.
