SIP Trunking & SBC Deep Dive is GVIT Academy’s advanced voice course, the natural sequel to VoIP & SIP Fundamentals. It takes you from “what is a SIP trunk?” to confidently engineering and troubleshooting carrier trunks behind a Session Border Controller. You will master trunk authentication (registration vs IP), numbering and caller ID, SBC architecture and configuration (realms, session agents, header manipulation), media handling and transcoding, high-availability and failover, trunk security and toll-fraud prevention, SIP normalisation, and a rigorous both-leg troubleshooting method. Examples are grounded in real platforms — Oracle SBC, carrier SIP trunks, Homer SIPCapture and Wireshark — so the skills apply directly on the job.
Advanced level. A module quiz after every topic, a final exam, and a practical both-leg SBC troubleshooting lab.
