Overview

This course is designed to give the delegate an understanding of the options for voice traffic within an LTE network. We look and describe the various options available including, CSFB, VoLTE and voice continuity in LTE.

The course will be enhanced with call flow example and SIP session examples. We will also investigate the full working of Session Initiation Protocol (SIP) and the IP Multimedia Subsystem (IMS), together with Private & Public Addressing.

Lastly we will explore the VoLTE Radio Performance and HSPA VoIP solutions.
