VoIP & SIP Fundamentals is GVIT Academy’s flagship voice course. It takes you from “what is VoIP?” to confidently reading a live SIP call in Wireshark, covering every core concept an engineer needs: SIP architecture and messages, call flows, SDP and codec negotiation, RTP and voice quality, NAT traversal and Session Border Controllers, SIP trunking, security and hands-on troubleshooting. Examples are grounded in real platforms — Cisco BroadWorks, CUCM, Asterisk, Oracle SBC and Homer SIPCapture — so the knowledge transfers straight to the job.

Built to match or exceed industry SIP certifications, with a module quiz after every topic, a final exam, and a practical Wireshark lab assignment.
