# Voice

> Assistants that answer the phone — shipped, but not self-serve.

Voice is a live channel on the platform. An assistant answers an inbound call,
speaks, uses the same knowledge and the same tools as it does on WhatsApp, and
the conversation lands in the same transcript with `channel: "phone"`.

<Warning>
  **It is not provisionable through this API.** There is no partner route that
  buys a number, and there will not be one until number procurement is something
  we can do on a merchant's behalf in the countries you sell in.
</Warning>

## Why it is not self-serve

A phone number is not a credential a merchant pastes. It is inventory somebody
buys, in a specific country, against a regulatory identity.

* **Procurement.** Numbers are bought per country from carriers, with stock that
  runs out and prices that differ by city.
* **KYC.** India, the UAE and most of the EU require verified business documents
  before a number can be assigned, reviewed by the carrier, taking days.
* **Porting.** A merchant who wants to keep the number already on their
  storefront is a manual process with a cutover window.

An API that pretended otherwise would return a 202 and then a support ticket.

## Enabling it for a merchant

Voice is enabled **per account** rather than sold on a plan. A merchant without
it is shown a request form, not an upgrade prompt — there is no tier that grants
it, so "upgrade" would send them somewhere that cannot help.

Talk to us with the merchant, the country and the expected call volume, and we
provision the number and enable the channel on that tenant. Everything after
that — the assistant, its knowledge, its tools, and the transcript your CRM
reads — is the API you already use.

## What you can do today

An assistant configured through
[Assistants](/reseller/assistants) serves voice as well as chat once the channel
is enabled on the tenant. Its conversations appear alongside every other channel
in [Conversations](/reseller/channels/whatsapp/conversations), with
`channel: "phone"` and no `channel.message_id` — a call has turns, not message
ids.

<Note>
  Voice conversations produce `conversation.created` and `message.received` /
  `message.sent` for each turn, on the same
  [webhook endpoint](/reseller/webhooks) as every other channel. Delivery status
  events are WhatsApp-only; a phone call has no equivalent.
