FreeSWITCH
FreeSWITCH media-server engineering for conferencing, gateways, IVR, and scalable voice applications.
FreeSWITCH is a capable media core for gateways, conferencing, IVR, and application-driven call control. We design FreeSWITCH deployments that sit cleanly behind SIP proxies or SBCs, with dialplan/XML or ESL-driven logic, recording, and operational visibility suited to production voice platforms.

Who it’s for
- • Voice platforms needing a robust media layer
- • Contact centers and application builders
- • Carriers using FreeSWITCH as a gateway or app server
Problems we address
- • Media and signaling responsibilities are tangled in one host
- • Call control logic is hard to test or version
- • Recording, conferencing, or WebRTC paths are unreliable
Expected outcomes
- • Clear FreeSWITCH role in a proxy + media architecture
- • Structured dialplan/ESL application patterns
- • Recording, codec, and WebRTC gateway baselines
