I spent a few hours last weekend finalizing my notes on IMS and VoLTE architecture. I’m sharing a section here, hoping it helps anyone interested in reviewing key aspects of IMS networks. This part covers essential topics such as registration processes, Quality of Service (QoS) mechanisms, and SIP routing. It provides a concise summary of these core areas to assist those seeking a quick review or clarification on IMS fundamentals.
Let me know your feadback! Take care ;)
