# Enable calling on a number

`POST /v1/messaging/phone-numbers/{id}/whatsapp/calling`

## Request

- Base URL: `https://apihub.co.il`
- URL: `https://apihub.co.il/v1/messaging/phone-numbers/{id}/whatsapp/calling`
- Auth: HTTP bearer

Enable WhatsApp Business Calling on a connected number. Configures
Meta calling.status=ENABLED with our Telnyx SIP endpoint, fetches and
stores the Meta-issued SIP password (encrypted), and snapshots the
customer's forward-to destination.


**Billing:** Request; paid actions are priced in credits (see GET /v1/messaging/prices) · **Rate limit:** 60/min

## Path parameters

- `id` string, required: Phone number record ID (from GET /v1/phone-numbers).

## Headers

- `Idempotency-Key` string
- `X-Tag` string

## Request body

- object
  - `accountId` string, required
  - `forwardTo` string, required: tel:+E164 / sip:... / wss://... destination
  - `forwardCallerId` 'business' | 'caller': Caller ID presented to the forward destination. caller = the WhatsApp user's number (sip: destinations only; ignored on tel: forwards). Fixes AI-agent trunks that reject seeing the business number call itself.
  - `sipAuthPassword` string: Stored encrypted, never returned by any endpoint.
  - `sipAuthUsername` string
  - `recordingEnabled` boolean
  - `callIconCountries` string[]
  - `maxCallDurationSeconds` integer: Hard cap (seconds) on a forwarded call; the carrier hangs up both legs when it fires. Safety valve against dead-air billing when a destination hangs up but the signal is lost.

## Response `200`

Completed

- object
  - `id` string: Execution id — stable across internal retries; use it with GET /v1/executions/{id}
  - `status` 'pending' | 'processing' | 'completed' | 'partial' | 'failed' | 'cancelled' | 'timeout'
  - `operation` string
  - `tag` string, nullable: Your X-Tag, if sent
  - `created_at` string, date-time
  - `completed_at` string, date-time, nullable
  - `output` object: Operation result (see each operation). While a Studio render is processing: `stage` (queued · transcribing · downloading · preparing · cleaning_voice · mixing_audio · rendering · finishing), `phase` (the engine's: download · prepare · voice · audio · encode · qa · upload, or null), `progress` (a percent, 0–100) and `progress_fraction` (0–1), `eta_seconds` (seconds left, never below 0) and `estimate_seconds`
    - `success` boolean
    - `forwardTo` string
    - `sipHostname` string
    - `callerIdMode` 'business' | 'platform': Caller ID the forward-leg callee sees on tel: forwards. business = this WhatsApp number; platform = a Zernio number (customer-brought number without verified caller ID).
    - `callingEnabled` boolean
  - `error` string, nullable
  - `usage` object
    - `credits_charged` number, nullable
    - `credits_reserved` number
    - `estimated_credits` number
    - `cost_source` 'provider_reported' | 'calculated' | 'estimated' | 'null', nullable
