OpenSIPS eBootcamp - Live online training - OpenSIPS 4.0

Run OpenSIPS in production without depending on anyone else.


The OpenSIPS Bootcamp - eight days, 32 hours, live with the founder of the OpenSIPS project and the author of the book. Half of every day is you at the keyboard, on a server that is yours for the fortnight.

All the knowledge transferred to the students is strongly backed up by practice sessions where you will get hands-on experience in handling OpenSIPS. The training is structured as 50% theory and 50% practice. A certification exam is included in the price. It is optional and can be taken on request after the end of the course.


Register for 30 November - 10 December 2026










Why engineers take it

Not to collect a certificate. To stop losing days to problems that should take an hour, and to stop needing someone else to make changes.

Solve it yourself
Read a trace and say exactly where the call died, instead of guessing and changing things until it works. You learn tracing, troubleshooting and observability, so every surviving turns into mastery.
Ship projects sooner
Most of the delay in an OpenSIPS project is not the writing, it is the not-knowing-which-module. You leave knowing which of the two hundred you actually need, and why the other hundred and ninety are not your problem.
Stop paying for help
If a consultant currently makes your routing changes, that is a recurring cost and a recurring wait. Eight days ends both.
Build a product on it
The same platform runs class-4 carriers, hosted PBXs, contact centres and IMS cores. You see all of it in the syllabus below, so you can judge what your product needs before you commit to building it.
Be certified
A timed exam is included with your seat, taken on request after the course, and the pass is listed publicly. It attests to what you know about OpenSIPS 4.0.

Who it is for

Carriers, operators
Service providers, mobile operators and carriers running open source in the core, or evaluating whether they can.
ITSPs, hosted PBX
Teams operating multi-tenant voice at scale, where registration load and failover are daily concerns rather than theory.
Consultants, VARs
Anyone who needs a jump start in the technology and bills for the result.
Product developers
Engineers building telephony applications and appliances on top of OpenSIPS rather than beside it.
Not for
Anyone new to SIP. This is not an introduction to the protocol - see Training Prerequisites below. Arriving without it wastes your fortnight and slows the room.

Bootcamp Syllabus

The complete syllabus of the training

How it runs

Nothing to install locally, and nobody sharing your lab.

Schedule
Four hours a day (15:00- 19:00 GMT), Monday to Thursday, two weeks. Fridays stay clear on purpose - for catching up and for private lab troubleshooting with a trainer.
Teaching
Live group conference for theory. Live group conference for labs. Live private conference when your lab will not behave. None of it is a recording.
Your lab
A cloud server with a public IP, provisioned for you, yours for the whole course. You are never queuing behind somebody else's broken configuration.
On your machine
An SSH client, a browser and a softphone. No local VMs, no containers, no VPN.
Version
OpenSIPS 4.0 throughout - the multi-threaded TCP release.
Before day one
The free QuickStart module and your server provisioning, both done in advance.

What we assume you already know

Stated plainly, because arriving without it costs you the fortnight.

Linux
Comfortable on a shell and in a text editor. You will spend eight days in both.
SIP
The basics of the protocol - what a request and a response are, what a dialog is. We go deep, we do not start from zero.
OpenSIPS
Enough to have installed it once and looked at a configuration file.
Programming logic
You will not write code. You will write logic - conditions, branching, variables applied to a dial-plan.
