Course Level: Beginner to Intermediate
The training focuses on real-world VoIP scenarios across on-prem and cloud calling environments, covering operational constraints such as WAN variability, NAT traversal, SIP trunk interoperability, and how to build monitoring and incident workflows around measurable voice performance (latency, jitter, loss, MOS where available).
What you will Learn in the VoIP Training
Understand SIP/SDP, RTP/RTCP, and how VoIP calls work end-to-end
Read SIP call flows (REGISTER, INVITE, BYE, re-INVITE) and common failure points
Identify VoIP ports, RTP ranges, NAT/firewall issues, and media path behaviour
Choose codecs (G.711/G.729/G.722/Opus) and understand bandwidth drivers (ptime/overhead/VAD)
Design QoS for voice (DSCP, trust, queuing, shaping) to minimise loss and jitter
Secure VoIP (toll fraud prevention, hardening, segmentation, TLS/SRTP overview)
Design and deploy multi-site VoIP (breakout options, redundancy, VPN impacts)
Troubleshoot using packet captures, RTP stats, monitoring baselines, and evidence packs
