# Get Call Mic Holder

`GET /api/voice/calls/{call_id}/mic-holder`

## Request

- Base URL: `https://api.dialogbrain.com` (the document declares no server; this is the origin it was published from)
- URL: `https://api.dialogbrain.com/api/voice/calls/{call_id}/mic-holder`
- Auth: none declared

Side-effect-free registry read: which tab (if any) holds the call's
operator mic. Unlike /publisher-check this neither claims nor revokes
and works for ANY call mode — it exists so a fresh tab on a GROUP call
can render the 'Continue the call here' chip the way 1:1 calls do
(task: tab-to-tab transfer for group calls, 2026-08-05).

## Path parameters

- `call_id` string, required

## Response `200`

Successful Response

- MicHolderResponse
  - `holder_tab_id` string, nullable

## Other responses

- `422`: Validation Error
