VoLTE IMS High level Architecture and E2E Call Flow

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.
