Course Overview

This course focuses on VoLTE detailed service scenarios and protocols.

Who should attend?

Everyone that wants to have an advance understanding of VoLTE, the services flows and deployment challenges.


Upon completion of this course the participant will be able to:
• Understated why do we need VoLTE
• Become familiar with 3GPP IMS protocol enhancements for Voice and Video
• Get Hands-on knowledge of IP based protocols used in VoLTE (SIP, SDP, RTP/RTCP, MSRP and Diameter)
• Understand the real challenges on developing and deploying VoLTE


The course includes these topics:
• IMS Protocols
• IMS Rich Telephony Protocols
