# Update voicemail

`PATCH /phone_numbers/{phone_number_id}/voicemail`

Update voicemail settings for a phone number. You can also configure a custom greeting by setting the `greeting` object: use `mode` `custom_greeting` together with a `media_name` that points to an audio file uploaded through the Media Storage API, or `mode` `default` to use the standard system greeting.

## Request body

- VoicemailRequest
  - `pin` string — The pin used for voicemail
  - `enabled` boolean — Whether voicemail is enabled.
  - `greeting` object — Controls the greeting a caller hears before leaving a voicemail. Set `mode` to `default` to play the standard system greeting, or to `custom_greeting` to play your own audio. When `mode` is `custom_greeting`, `media_name` is required and must reference an audio file already uploaded to your account through the Media Storage API.
    - `mode` 'default' | 'custom_greeting' — The greeting mode. `default` plays the standard system greeting. `custom_greeting` plays the audio referenced by `media_name`.
    - `media_name` string, nullable — The name of the media file to play as the greeting. Required when `mode` is `custom_greeting`; ignored when `mode` is `default`. The value must match the `media_name` of a file you previously uploaded with the Media Storage API (`POST /v2/media`).
