Kamailio and FreeSWITCH support, straight from the engineers.
We design, run and fix SIP platforms for businesses that can't afford their voice platform going down, and build AI voice agents on top of them. Twenty years running Kamailio in production, 24/7 support, and no account managers between your problem and the person fixing it.
24/7 emergency support for production platforms.
Kamailio down? Call now.
24/7, an engineer who has run Kamailio in production since 2005 answers the phone. Call if you're seeing any of these:
- Registrations failing or phones dropping offline
- Calls not routing, one-way audio or wrong caller ID
- Dispatcher, load balancer or failover not behaving
- High CPU, memory or shared-memory exhaustion under load
- TLS certificate, WebSocket or WebRTC problems
- SIP scanners, brute force or toll-fraud traffic
- An upgrade or config change that's gone wrong

Learn moreSmall team, straight answers
We've built platforms from multi-site, multi-platform estates down to the simplest thing that works. Customers have trusted us to design, deploy and run them since the early days of VoIP.
Straight answers
A clear opinion on what's wrong, what to do about it and what it will cost. No upsell.
Hands-on
We do the work ourselves. Nothing is handed off to a junior or a subcontractor.
There when it breaks
24/7 emergency support for production platforms, on hourly rates or a support contract.
Security first. Open source at the core.
Security is part of the design
Your voice platform carries your customers' calls and your revenue. We treat security as part of how a platform is built, not something added after an incident: authentication, fraud limits, encryption and monitoring are in scope from the first conversation.
- NDA first. We'll sign your NDA before you share configs, call records or network details.
- It's one of our services. Platform security and monitoring, and SIP fraud and abuse protection for Kamailio and FreeSWITCH platforms.
- We practise it here too. This site sets no cookies and loads no third-party scripts or trackers. Security researchers can reach us via our security.txt.
Built on the open-source community
Kamailio, FreeSWITCH, rtpengine and LiveKit are open-source projects, written and maintained by their communities. Everything we do stands on that work, and we treat it that way.
- Upstream, not around it. We point you to each project's own documentation, releases and community channels.
- Supported releases. We'll always recommend running a release the project still maintains, because that's where security fixes land.
- Support the projects. If your business runs on them, consider backing Kamailio and FreeSWITCH too.
In production every day
We don't just consult. We support and develop live voice platforms day to day, which is how we keep our Kamailio, FreeSWITCH and AI skills sharp.
