VoLTE Call Flows: Practical Wireshark Analysis for IMS & SIP

VoLTE Call Flows: Practical Wireshark Analysis for IMS & SIP free download

Analyze real VoLTE IMS call flows using Wireshark. Learn SIP, SDP, and hands-on packet tracing on PCAP files provided.

Master IMS and VoLTE call flows by learning how to analyze real network traces(Providing you with PCAP traces) with Wireshark — the most powerful tool for protocol inspection.

This course is designed for telecom engineers, students, and professionals who want to understand how VoLTE works in practice, not just in theory. You'll explore real SIP, Diameter, Megaco and RTP messages captured from actual VoLTE sessions and learn how to interpret every step using Wireshark.

Whether you're preparing for interviews, troubleshooting live networks, or trying to strengthen your knowledge of IMS and VoLTE (PCAP Traces are provided to you), this course will give you the skills you need through realistic examples and deep packet analysis.

What You Will Learn:

• Step-by-step VoLTE registration, MO, and MT call flows

• Wireshark techniques for filtering, decoding, and inspecting VoLTE and IMS messages

• How SIP, SDP, Diameter, RTP, and bearer setup interact across LTE and IMS

• End-to-end media path tracing and QoS validation using real packet captures

• Understanding dedicated bearer creation and mapping media to it

• SRVCC & ICS and how to spot them in traces

• Hands-on interpretation of core network signaling, including S-CSCF, P-CSCF, PCRF, MGCF, and more

Why Take This Course?
