Voice-triggered dispatch, clearly connected.

A spoken phrase calls your list in order. Whoever answers hears the announcement and is connected.

The console shows each call leg as it happens, so the duty desk sees who answered and who is connected.

The Voxstead console during a run: the state banner, the call legs of each party and the event timeline.

How a run works

Four steps, each one an event you can follow on the console and in the run timeline.

  1. Step 1

    Spoken trigger

    Someone at the desk says the trigger phrase, “Connect the duty desk”. The Start run button and a typed phrase start the same run.

  2. Step 2

    Attempts in order

    Destinations are called one at a time, top to bottom. A busy line or a ring timeout moves the run to the next one.

    Attempts list: Duty engineer busy, Facilities on call no answer, Building services ringing with 7 seconds left.
  3. Step 3

    Announcement

    The first destination to answer hears the announcement. The console shows this as Answered: a network answer, which a voicemail box can also give.

  4. Step 4

    Live connection

    The announcement stops before the live connection starts. The responder joins the desk, or is handed to an operator, and the audio is measured both ways.

Walkthrough

One minute of the public simulator, recorded from the running workspace.

A busy line and a ring timeout, an answer and the announcement, then an operator handoff with two-way audio measured, a hang up and the ended run. The recording has no sound.

What the workspace does

The workspace runs in your browser on a simulated line. The integration with a real phone system and a relay is a separate set of parts.

In the workspace today

Simulated
  • Sample scenarios

    Five scripted runs, from a third contact answering to a line interrupted mid-announcement. They need no microphone.

  • Routes

    Ordered destinations, ring timeout, retries, active hours, and direct connect or operator handoff, with a summary before saving.

  • Announcements

    Upload or record audio, preview it on its real waveform and assign it to a route.

  • Runs

    Every run made in the browser as a timeline with absolute and elapsed times, exported as CSV or JSON.

  • Two-way audio test

    Two WebRTC endpoints in the page send audio both ways, and each side reports what it receives.

Integration with a real line and a relay

These parts are delivered as code and commissioning steps. They are disabled by default and have not been run against real telephony or hardware in this build.

  • Asterisk ARI adapter

    Not configured

    Places calls through your own Asterisk, over a SIP trunk or extension. Real calls need an allow list and a switch set on the kit.

  • Linux and Raspberry Pi agent

    Not configured

    A Python agent with the same run rules as this workspace, a hardened systemd unit and a check command that reads the configuration.

  • GPIO relay adapter

    Not configured

    Drives one output line through libgpiod to an isolated solid-state output, with an optional feedback input. The output is off at start.

The kit

The intended kit is a small computer at the desk with a microphone and speaker, a wired network connection to your phone system, and an isolated output that switches on when the call is answered.

Concept: a microphone and speaker and a wired network connect to a Raspberry Pi class computer. One GPIO signal drives an isolated solid-state output stage, which switches a load on its own supply.Microphone and speakerUSB array, echo cancellingRaspberry Pi class computerVoxstead edge agentNetworkWired Ethernet to your AsteriskIsolated output stageOptocoupled solid-state relayYour loadPowered from its own supplyUSB audioSIP via ARIGPIO, 3.3 Vcontactisolation
