Evolution
Around 2010, our consulting endeavours coalesced into CSRP,
our Kamailio-based routing product for SIP trunking operators. CSRP has been our core business since 2011, and
our main focus is on the development of CSRPv2, the next generation of CSRP to serve modern operators'
increasingly complex needs beyond the traditional SIP trunking / Class 4 business model.
However, we continue to do some custom work for a small number of select customers, and we will probably
always do so. We seek mutually high-value customer relationships, win-win solutions,
and the imagination and energy of building new things.
For much of our history, we distinguished ourselves in the VoIP consultancy space with a focus on
high-performance Least Cost Routing (LCR) and domain knowledge of PSTN interconnection in the US.
Relatively few VoIP providers understood how the "other side" of the PSTN fence works, despite
its technical centrality and impact on the upstream cost picture. Our
background in the carrier world allowed us to bridge this gap.
This type of knowledge continues to serve us well, but the dominant themes of our work have morphed,
mirroring general industry trends. Today, our skill portfolio also draws heavily on:
- Docker, containerisation, configuration management, service discovery, and cloud-native architecture;
- REST APIs, connectors and integration paths;
- WebRTC libraries, browser communication APIs, JavaScript front-end development, and the interaction among these;
- Mobile and browser push notifications;
- CI/CD, end-to-end test automation, and automated deployment.
Beyond building, we love to share our knowledge and experience--in many cases acquired the hard way--to
help others drive around common pitfalls and thrive!
