What is Telepath?
Telepath is the Real-Time Voice AI Infrastructure that bridges the gap between traditional telephony (PSTN/SIP) and modern AI Agents. It functions as a zero-latency WebSocket bridge, enabling direct connections between SIP carriers and AI voice providers.Core Architecture
Telepath operates in four simple steps:- A PSTN/carrier sends audio via SIP to Telepath
- Telepath converts SIP/RTP into a WebSocket stream
- An AI agent (OpenAI, ElevenLabs, or custom) processes the stream
- Telepath returns the response to the caller in real-time
