Telecommunications

What is technically different in this industry #

Real time without a buffer. With voice there is no re-buffering. Latency, jitter and packet loss are immediately audible, which is why QoS optimisation and media path testing are a fixed part of the work.

Exposed components. A SIP network border sits on the open internet and is scanned continuously. DDoS protection, rate limiting and hardened configuration are baseline, not extras.

Multi-tenancy from the start. Extensions, ring groups, queues and call rules have to be cleanly separated — retrofitting that is barely feasible.

Long product lifecycles. Phone systems are operated for years and extended step by step. This is precisely where our longest reference sits.

What we have done here #

We have owned Phonalisa, a complete IP telephony platform, architecturally since our founding in 2009 — from the signalling layer through the web interface to the cross-platform CTI client, including our own session border controller, test automation, user documentation and support.
