Three senior engineers. No middlemen.
Kamailio, FreeSWITCH and SIP support from engineers who've run them in production since 2005 — plus the Linux, cloud, AI and security work around them. Call and you'll speak to the engineer doing the work, not an account manager.
Kamailio down? Call now.
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
- Database, htable or rtpengine errors in the logs

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.
