LATEST UPDATED QUESTIONS
30 Verified Questions | With Verified Answers & Rationales
Foundational 3CX PBX Administration | VoIP | SIP Trunking | IVR | System Security
Aligned to the 2026/2027 3CX Academy Basic Certification Curriculum
, Key Features
✓ 3CX architecture, deployment, and hosting requirements - on-premise, cloud, and hosted models with
PostgreSQL backend and NGINX web server.
✓ Initial system setup, licensing, and team configuration - FQDN/SSL provisioning, edition selection (Free,
PRO, Enterprise), and license activation workflow.
✓ SIP trunking, VoIP protocols, and inbound/outbound rules - certified trunk templates, DID routing,
prefix-based outbound rules, and SIP TLS/SRTP encryption.
✓ Extension management, ring groups, and digital receptionist (IVR) setup - extension provisioning, hunt
strategies, IVR menus, and forwarding rules.
✓ 3CX Web Client, mobile app provisioning, and basic troubleshooting - QR-code provisioning, 3CX Tunnel
for remote access, and one-way audio diagnostics.
Updates for 2026
▸ Updated 3CX V20 feature set including advanced AI integration and WebRTC
enhancements: the 2026 curriculum emphasizes the unified NGINX-based web stack, AI-assisted call
transcription and summary in the Web Client, and improved WebRTC media handling for browser-based
calling.
▸ Revised security protocols for SIP TLS/SRTP encryption and firewall checker utilities: new
default recommendations enforce TLS 1.3 for SIP signaling, SRTP for media, automated Let's Encrypt
certificate renewal, and an enhanced Firewall Checker that validates STUN, port forwarding, and RTP range
in a single pass.
▸ New 3CX Academy guidelines for multi-tenant hosting and cloud instance management:
hosters must follow the revised deployment standards for instance isolation, backup segregation, and
resource sizing, with updated training modules covering the 3CX Hoster Portal and cloud-instance lifecycle.
Abstract
This document presents a 30-question actual exam for the 3CX Basic Certification H Exam, aligned with the
2026/2027 3CX Academy curriculum and current VoIP and PBX deployment standards. It targets the
foundational knowledge required to install, configure, and administer a 3CX V20 phone system in small to
mid-sized environments. The five covered domains span installation and architecture, system setup and
licensing, SIP trunking and call routing, extensions and ring groups with IVR, and client/mobile app
provisioning with troubleshooting. Each question includes a verified correct answer, a concise rationale
grounded in 3CX official documentation, an explanation of why distractors are incorrect, and a specific
reference to the 3CX Academy training module or VoIP standard. The exam emphasizes reliable VoIP
communications, secure signaling and media via SIP TLS and SRTP, correct NAT traversal with STUN and the
3CX Tunnel, and disciplined system security through validated backups and firewall configuration. Candidates
who master this content will be equipped to deploy and manage a basic 3CX PBX in production with
confidence.
