What we do

Services

Voice platforms first, and the AI, security and infrastructure work around them, all delivered by the engineers themselves.

How we work

Small 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.

Platforms we build

We design and develop JMB Technology's Call Platform

Kamailio Support's engineers are directly involved in designing and developing Call Platform by JMB Technology, an enterprise business communications platform. It's built the way we'd build yours: telecoms at the core, and the customer experience layered over the whole ecosystem.

On top of everything

Customer experience

What people actually see and use: the Pulse app for business calls and team chat wherever they're working, and for partners a dedicated, white-label platform with its own customer portal, admin console, published app and Companion for mobile management.

Intelligence and automation

AI across the call journey

AI Voice Agents that answer enquiries, qualify callers and book appointments; AI outbound that follows up old enquiries and hands the opportunity to the team; and Call Intelligence that finds key moments and scores call quality.

At the core

Telecoms engineering

Numbers, routing and call handling on the inbound platform: calls routed by opening hours, caller choices and team availability. The same voice and SIP engineering we do for our clients, running in production every day.

Why it matters to you: the engineers who design, build and support a live enterprise platform are the same engineers who'll work on yours.

What we stand for

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.
