Hybrid FreeSWITCH / Twilio on top of React Dialer
Budget: $10 – $30 USD
Hi, I built a dialer using aistudio (React) and want to get the dialing functionality integrated.

By using the Hybrid Approach, you are essentially using FreeSWITCH as your logic and media engine (to handle WebRTC and call control) and Twilio merely as the carrier (to bridge calls to the PSTN).
This approach drastically reduces costs (Twilio Elastic SIP Trunking is significantly cheaper than the Twilio Client SDK) and gives you granular control over the call audio.
The Architecture Blueprint
1. React Frontend: Uses SIP.js (or similar) to connect to FreeSWITCH via WebRTC (WSS).
2. FreeSWITCH (Middle Layer): Acts as the PBX. It bridges the WebRTC stream (from the browser) to a standard SIP stream.
3. Twilio (Carrier Layer): Connected to FreeSWITCH via Elastic SIP Trunking. It takes the SIP stream and terminates it to the PSTN (real phones).
