FreeSWITCH consultancy and support
Media handling, PBX, conferencing and voice applications on a platform we've run since 2005.
24/7 emergency support for production platforms.

FreeSWITCH is the media and application layer that usually sits alongside Kamailio: PBX features, conferencing, IVR, recording and transcoding. We design it, integrate it and keep it running.
We've been installing and customising FreeSWITCH since around 2005, often paired with Kamailio at the edge. Whatever the size of the estate, you talk directly to the engineer working on it.
