FreeSWITCH & OpenSIPS Masterclass

Job ID: 40314121

Budget: $30 – $250 USD

I’m looking for a patient, technically-savvy trainer who can take me from my current beginner level to confidently performing advanced troubleshooting and maintenance on both FreeSWITCH and OpenSIPS.

Scope of the masterclass
• Begin with a quick foundation to be sure my basics are solid.
• Move rapidly into deep-dive modules on:
– Diagnostics and logging (call traces, SIP capture, fs_cli, Homer)
– Security best practices (TLS, ACLs, antifraud rules, topology hiding)
– Performance optimization (load balancing, caching, tuning Sofia/SIP and dispatcher settings)
• Emphasise hands-on configuration: I want to work through real scenarios, replicate common failures, and fix them live.
• Provide recorded sessions, editable lab configs, and concise step-by-step notes so I can revisit material later.

Teaching format
Zoom or similar screen-share sessions, spread over several days or weekends to fit around my schedule. I’m open to suggestions on pacing, homework labs, and any recommended tools (Kamailio, sngrep, Wireshark, etc.) that help illustrate concepts.

Acceptance criteria
By the end of our engagement I should be able to:
1. Read and interpret FreeSWITCH and OpenSIPS logs to isolate issues.
2. Secure a new deployment following industry best practices.
3. Benchmark and fine-tune the stack to handle higher call volumes without quality loss.

If you have prior training materials, real-world VoIP deployment experience, and enjoy interactive teaching, I’d love to hear how you would structure the sessions and the approximate hours you expect we’ll need.
