AudioSocket

AudioSocket is an Asterisk channel driver and application that enables real-time, bidirectional audio streaming over TCP connections. Unlike traditional audio interfaces that work with files or conference bridges, AudioSocket provides a raw audio stream that external applications can consume and inject audio into, making it ideal for AI-powered speech analytics, real-time transcription, and voice bot integrations.

How It Works in VICIdial

AudioSocket operates by establishing a TCP connection between Asterisk and an external audio processing server. When a call is routed through an AudioSocket channel, the raw RTP audio is converted to a simple PCM stream and sent over the TCP connection. The receiving application can process the audio in real time — performing speech-to-text, sentiment analysis, or keyword detection — and optionally send audio back to be injected into the call.

In VICIdial contexts, AudioSocket can be integrated into the dialplan to tap into call audio without disrupting the normal call flow. For example, a call can simultaneously be in a ConfBridge conference (for agent handling) while AudioSocket streams the audio to an AI analytics engine.

This is different from AGI or FastAGI, which handle call control logic but do not provide direct audio access. AudioSocket is specifically designed for media streaming use cases.

Why It Matters

AudioSocket opens the door to modern AI integrations in VICIdial environments. Real-time speech analytics can detect customer sentiment, identify compliance keywords, and trigger supervisor alerts during live calls. AI-powered quality control systems use AudioSocket to analyze every call in real time rather than reviewing recordings after the fact.

As AI transforms call center operations, AudioSocket provides the bridge between VICIdial’s Asterisk-based telephony and modern speech processing platforms. See the AI quality control feature page and AI coaching features for practical applications of real-time audio streaming.
