# How We Built a Telephony AI Framework That Eliminates 90% of Voice Infrastructure Complexity

### Most developers underestimate how hard voice AI actually is.

To build a production-ready calling agent, you need to integrate:

– SIP signaling

– 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:

```plaintext
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.
