# Features

> Vision, group-call etiquette, outbound call-backs, meeting recap, governance, and security.

Both plugins implement the same feature set over the shared CVI bridge.

## Voice

* **Realtime** (speech-to-speech) **and streaming** (STT → agent → TTS), both with **barge-in**.
* **Bilingual Arabic / English** - wake-phrase + filler stripping, whole-utterance verbal interrupts.
* **DTMF / IVR** keypad input.
* **Roster greeting by first name** + a "thinking" expression while it works.
* **Realtime delegation** - `consult` (inline) and `agent_task` (background) hand work to your agent.

## Vision

* `look_at_screen` over **camera + screen-share** frames.
* **Continuous vision** - the latest *changed* frame is pushed (\~6 s) with no forced response.
* **Scene-change ambient** notices + **retroactive** lookback (16-keyframe ring, attributed).
* **Per-call spend cap** via `maxVisionPerMinute` to bound cost.

## Avatar (CVI rendering cues)

* **Expression cues** - neutral / happy / sad / surprised + thinking.
* **Viseme `speech.marks`** lip-sync.
* **`show_to_caller`** → fullscreen or picture-in-picture image, captions, paced slideshow.

## Group & meeting

* Per-participant attribution; **speaks only when addressed** (2+ humans → wake phrase + follow-up
  window; 1:1 always responds). Race-free on realtime (auto-response off in meetings).

## Outbound - "call me back"

* `call_me_back` places an outbound call via StandIn's HMAC, SSRF-guarded endpoint;
  **greets on answer**; correlates the pending result with a TTL. Voicemail fallback is handled by StandIn.

## Chat & governance

* **"Ask about this"** message action · **voice-message transcription** (opt-in) ·
  **audit-log channel** (opt-in, loop-guarded) · **DLP outbound redaction** (opt-in) on text,
  adaptive cards, and captions.

<Note>
  These live in the Teams **messaging** adapter, not the voice bridge - enable your runtime's Teams
  chat channel/plugin alongside the voice plugin to get them.
</Note>

## Meeting productivity

* **End-of-meeting recap** (opt-in) + on-demand **`post_meeting_minutes`**, posted to the Teams chat
  with per-speaker attribution, the minutes attached as a Word **`.docx`** file card. On Hermes the
  card rides the Bot Framework attachment contract (bot credentials only, no SharePoint); SharePoint
  upload (`Sites.ReadWrite.All`) remains an optional path where configured.

## Security

<CardGroup cols={2}>
  <Card title="HMAC bridge" icon="key">
    Every StandIn connection is HMAC-SHA256 signed with a replay guard and a ±60 s window. The
    `sharedSecret` must byte-match the secret set in StandIn.
  </Card>

  <Card title="Caller allowlist" icon="user-shield">
    Restrict who the bot answers by AAD object id - closed by default when an allowlist is set.
  </Card>

  <Card title="Recording gate" icon="circle-stop">
    No media-derived data is processed until the call's recording status has been signalled.
  </Card>

  <Card title="Your own bot identity" icon="id-badge">
    Bring your own Azure AD bot - your tenant owns it, with a per-bot HMAC secret never shared across tenants.
