# Update Phone Number

`PUT /phone_numbers_admin/phone-numbers/{phone_number_id}`

## Path parameters

- `phone_number_id` string, uuid, required

## Request body

- PhoneNumberUpdateAPI — Operator-editable phone number configuration. ``language`` is validated against the supported-language registry so a number can never be pinned to a language routing cannot serve. ``intent_context`` is free text that reaches the agent's system prompt, so it carries the same prompt-delimiter guard as ``condition`` and ``hunt_group_name``, and a length cap — a prior is a sentence or two, and an essay would drown the rest of the prompt.
  - `external_assistant_id` string, nullable
  - `outbound_voice_agent_id` string, uuid, nullable
  - `inbound_voice_agent_id` string, uuid, nullable
  - `livekit_dispatch_rule_id` string, nullable
  - `sip_prefix_to_strip` string, nullable
  - `sip_default_region` string, nullable
  - `language` string, nullable
  - `intent_context` string, nullable
