VoWiFi Training

VoWiFi Training, learn about Voice over Wi-Fi (or VoWiFi) concepts, principals, architecture and design using IMS, SIP and EPC core.

VoWiFi training 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.

Learn about all the tricks about VoWiFi and transparent and seamless mobility across Wi-Fi, LTE, 3G and 2G platforms for all voice and messaging services.

TONEX  VoWiFi training covers all aspect of VoWiFi, VoLTE, small cells along with IMS control and Diameter and SIP protocols.

VoWifi training provides an intermediate-to-advanced-level technical analysis of VoWiFi architetcure, 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.

In this course, you will learn about VoWiFi, EPC core, 3GPP AAA server and proxy, ePDG, all new VoWiFi interfaces, signalin
