Requirements

you will need wireshark for the analysis of the traces and also actix analyzer

Description

This course entails the basic overview of VOLTE and its principles.

The need for Voice over LTE and why most operators need to deploy it

It explains and defines the principles behind VOLTE and how to trouble VOLTE network.

we will also look at the SRVCC functionality in VOLTE and the nodes involved in SRVCC.

in this course we will discuss how to use tools like actix for troubleshooting the radio side of the VOLTE network

in addition, we will use tracing tools like Anritsu to troubleshoot the IMS network and also analysis the trace files using wireshark
