Course catalog
The full SIP Train Phase 1 catalog. Each course maps to a specific certification track and stands alone as a deep technical resource you can refer back to long after the exam.
Foundation track
Two courses. The complete fundamentals of SIP signaling, transactions, dialogs, registration, media negotiation, and real-world SIP behaviour.
9 modules · 41 lessons · ~7.5h structured content · 6 PCAP labs
Architecture, headers, methods, response codes, transactions and dialogs, registration and digest authentication, basic SDP, and protocol-level troubleshooting. Closes with a CVA exam-prep module.

PRACK and 100rel, UPDATE, REGISTER in the real world (outbound, NAT, keep-alives), SUBSCRIBE/NOTIFY for BLF and presence, REFER and call transfer, Replaces and attended transfer, session timers, target refresh.
Course outline →Intermediate track
Two courses. Media transport at depth, session border controllers, and the operational engineering layer above CVA.
9 modules · 44 lessons · ~12-14h commitment · 6 PCAP labs
RTP packet format, RTCP SR/RR analysis and the RTT/jitter formulas, codecs (G.711, G.722, G.729, Opus, AMR), RFC 4733 DTMF, jitter buffers and PLC, SRTP keying (SDES, DTLS-SRTP, MIKEY), and recognition-depth WebRTC media.

B2BUA mechanics, the Record-Route doubling rule, Contact rewrite and the 32-second-after-200-OK mystery, topology hiding header by header, transcoding and media anchoring modes, HA pair models, WebRTC at full operational depth, and SIP fraud mitigation.
Course outline →Advanced track
Two courses. Carrier-class voice engineering, SS7/SIGTRAN, and the operational realities of tier-1 telco voice.
9 modules · 46 lessons · ~14h commitment · 7 PCAP labs
SS7 architecture (SSP/STP/SCP, point codes, link types), ISUP at byte depth (IAM/ACM/ANM/REL with Q.850 causes), SCCP/TCAP with MAP/INAP/CAMEL, SIGTRAN adaptation layers, RFC 3398 ISUP-to-SIP mapping with RFC 3326 Reason, SIP-T encapsulation, and ISDN PRI / MGCP recognition.
Course outline → Available at launch10 modules · 47 lessons · ~14h commitment · 6 labs
Carrier interconnect taxonomy, STIR/SHAKEN identity attestation at full depth, LNP at carrier-decision depth, MGCP/Megaco operational, transcoding chains and codec licensing, WebRTC-to-carrier interworking, IMS interconnect with Cx/Sh/Rx Diameter, CNAM, 800-routing, and CALEA recognition.
Course outline →No. Each course stands alone, and you can buy any course individually. That said, CVP material assumes CVA-level fluency, and CCVE material assumes CVP-level fluency. If you're a working carrier engineer and want to challenge straight into CVP or CCVE, you can - the certification exam is the same regardless of which courses you took to prepare for it.
Yes. Final certification exams are proctored online. Module quizzes are open-book and self-paced. The proctored model is part of how we keep the credential meaningful.
A 7-day cool-off applies before retake. You get a feedback report showing which topic areas to review, and your second attempt is included in the certification fee.
The first lesson of every course is fully open - no signup, no email capture. Read it, run the lab if there is one, and decide whether the depth matches what you need.
All six courses, across CVA, CVP, and CCVE, are available at launch. See pricing or get in touch about team plans.
