Most developers underestimate how hard voice AI actually is.
To build a production-ready calling agent, you need to integrate:
– SIP signalling
– Real-time audio streaming
– Speech-to-text
– LLM orchestration
– Text-to-speech
Each layer introduces latency, failure points, and vendor dependencies.
That’s where Siphon comes in.
What Siphon Does
Siphon acts as a middleware layer between telephony systems and AI models, abstracting the entire pipeline into Python.
You define:
agent=Agent(...)
And Siphon handles:
– WebRTC streaming
– SIP negotiation
– Interrupt handling
– Model orchestration
Key Features
1. Sub-500ms latency
Human-like conversations require near-instant responses — Siphon achieves this using WebRTC streaming.
2. Modular AI stack
Swap LLMs, STT, and TTS providers with a single config change.
3. Zero-config scaling
Spin up more workers → Siphon auto-load-balances calls across nodes.
4. Data sovereignty
All data stays in your infrastructure — no third-party data leakage.
Why It Matters
Instead of spending months on infra, you can focus on:
– Agent logic
– Business workflows
– User experience
👉 Siphon turns voice AI into a developer problem, not an infrastructure nightmare.
