Introduction:

Voice over WiFi Training | VoWiFi Training Course with Hands-On Exercises (Online, Onsite and Classroom Live)

With this Voice over WiFi Training | VoWiFi Training, you will learn about Voice over Wi-Fi (or VoWiFi) concepts, principals, architecture and design using IMS, SIP and EPC core. This course covers all the principals carriers need to leverage residential and enterprise Wi-Fi Access Points transparent along with interworking concepts and challenges between IMS, 3G, small cell, Wi-Fi, and 4G/LTE.

Voice over WiFi Training provides an intermediate-to-advanced-level technical analysis of VoWiFi architecture, registration, call-setup, location update, mobility and security procedures. Protocol traces and logs are provided mapped to procedures and discuss various methods, functions and signalling parameters.

Duration: 2 days
