Flexible telecommunications platform for voice, video, and messaging.

FreeSWITCH is a powerful and versatile communication platform


It is an open-source software application that serves as a highly flexible and programmable telecommunications platform. It is designed to handle voice and video communications over the internet and traditional telephony networks. FreeSWITCH can act as a software-based Private Branch Exchange (PBX) for voice calls, a media server for processing audio and video, and a platform for building various real-time communication applications.


Using a modular architecture it allows developers to customize its functionality according to specific requirements. It supports a wide range of protocols, codecs, and devices, making it suitable for a variety of applications, from simple call routing to complex conferencing and call center solutions. It can be integrated with other software and services to create comprehensive communication systems.


Our experience installing, configuring and customising FreeSWITCH spans back to around 2005.

Having worked in telecoms since 1999, our team of engineers already knew how telecoms worked, the shift to VoIP was on the rise and although some teething issues was still evident, the belief we had it would come good kept us on track. As part of the early adopters, we have witnessed SIP become the pinacle protocol that underpins the world of telecommunications. Allow us to share the extent of our experience with you or your engineering team.
