Voxa.Transports.Telephony

Shared telephony media-stream transport for the Voxa voice pipeline (VTL-001). Runs a phone call in and out of a Voxa pipeline over a WebSocket — no WebRTC, no SIP, no ICE/TURN.

Telephony providers (Twilio Media Streams, Azure ACS) bridge the PSTN/WebRTC side themselves and hand you JSON messages over a WebSocket whose payload is base64-encoded audio. This package is the vendor-neutral half of that:

  • TelephonyMediaStreamSource / TelephonyMediaStreamSink — a PipelineSource/PipelineSink pair that own the WebSocket read/write loops, the bounded outbound queue with the barge-in epoch purge, and the 8 kHz ↔ pipeline-rate resample bridge.
  • ITelephonyMediaCodec — the small per-vendor seam (parse one inbound message → a transport event; serialize outbound audio / clear / mark). The base does the μ-law decode and the resample, so a codec is just JSON framing.
  • MuLaw — allocation-free G.711 (μ-law / PCMU) encode/decode.

The VAD → STT → agent → TTS chain in the middle is untouched: the same DefaultVoicePipelineComposer that builds the native WebSocket route builds the telephony route. Telephony is purely an edge skin.

The Twilio codec + TwiML endpoint live in Voxa.Transports.Twilio. This base package has no ASP.NET dependency — it operates over any System.Net.WebSockets.WebSocket.

Pre-alpha; the public API still moves.

Package Downloads
Voxa

Batteries-included Voxa package. One package reference: AddVoxa(cfg) + MapVoxaVoice("/voice").UseDefaults() gives a working voice bot with STT, TTS, VAD, and an OpenAI chat agent — no knowledge of frames required.
Voxa.Transports.Twilio

Twilio Media Streams transport for the Voxa pipeline (VTL-001). MapVoxaTwilioVoice("/twilio") serves the TwiML webhook and accepts the media WebSocket, running a phone call through the SAME composed VAD→STT→agent→TTS pipeline as the native route — with barge-in. The wire is hand-rolled JSON over the shared Voxa.Transports.Telephony base (μ-law 8 kHz); no Twilio SDK, no WebRTC. Includes X-Twilio-Signature validation.
