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.
Course outline · Try Module 1 free → Available at launch9 modules · 39 lessons · ~10.5h commitment · 7 PCAP labs
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.
Course outline → Beta access available9 modules · 44 lessons · ~12-14h commitment · 6 paired-capture labs
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 → Beta access available10 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.
SIP-101 and SIP-102 are available at launch. See pricing or get in touch about team plans.
