🚀 Dive into the World of SIP and PSTN Network Interconnections!

Course Title: Interconnexions entre Sip et Pstn: Architectures Réseau et Messages Sip / Pstn

Course Headline: Unlock the Secrets of SIP and PSTN Communication Synergy! 📡🤝

Course Description:

The Essence of Telephony Convergence: SIP (Session Initiation Protocol) has become the cornerstone of modern telephony, yet it operates hand-in-hand with legacy protocols like ISUP (Intelligent Network-Signalised User Part) within the PSTN (Public Switched Telephone Network). But what happens at their intersection?

Your Journey Through SIP and PSTN Interworking: This course is meticulously designed to unveil the intricate mechanisms behind interconnections between SIP-based systems and the traditional PSTN. From understanding how a SIP INVITE message is crafted at a gateway when receiving an IAM (ISUP message) to grasping the nuances of "EARLY MEDIA" for seamless media flow, this course will cover it all.

Course Outline:

Partie I: Global Overview of SIP Interacting with PSTN

• Callflow analysis between SIP and PSTN
• Error handling in call flows from both perspectives
• Equivalence between SIP and PSTN transaction codes

Partie II: Early Media

• In-depth explanation of the "EARLY MEDIA" concept
• Examination of the "Early media callflow" and its role
• Discussion on "Early media offer" vs. "Delayed offer"

Partie III: Gateway vs. Default Router

• Definitions and distinctions between gateways and default routers
• Insight into their respective roles in network architecture

Partie IV: SIP-T and PSTN Bridging

• Contextual understanding of SIP-T's role in bridging
• Exploration of practical use cases

Partie V: SS7, ISDN, and SIP Correspondence

• Detailed analysis of the architectures
• Correspondence between SIP and ISUP transaction codes
• Real-world scenarios involving PSTN-to-PSTN calls via SIP encapsulation

Partie VI: SIP and DTMF

• Comprehensive introduction to Dual-Tone Multi-Frequency (DTMF) technology
• Differentiation between in-band and out-of-band DTMF
• Exploration of RFCs 2833 and 4733 for SIP-based DTMF signaling
