In this video we’ll take a quick look at how VoLTE and IMS work together.
First, we’ll go over the high-level architecture of VoLTE and IMS, showing the main network components involved in delivering voice over LTE.
Then, we’ll briefly explain the end-to-end call flow in IMS - how a call is initiated, how SIP messages are exchanged, and how the connection is set up between two users.
This is just a simple overview to help you understand the core concepts without going too deep. Let’s get started.
