# Get a SIP trunk gateway

`GET /v1/voice/trunks/{trunk_id}/gateways/{gateway_id}`

## Request

- Base URL: `https://us1.platform.bird.com`
- URL: `https://us1.platform.bird.com/v1/voice/trunks/{trunk_id}/gateways/{gateway_id}`
- Auth: one of:
  - HTTP bearer
  - API key in cookie `bird_session`

Returns a single gateway by ID. Returns a 404 `not_found_error` if the trunk or the gateway does not exist in the workspace.

## Headers

- `X-Workspace-Id` string
- `X-Organization-Id` string

## Response `200`

Gateway with its current routing and connection settings.

- VoiceTrunkGateway: One address an inbound call to this trunk is forwarded to, and how that peer wants the call's two numbers spelled. A trunk can have several, tried in priority order until one answers.
  - `id` string, required
  - `trunk_id` string, required
  - `sip_uri` string, required: SIP URI an inbound call to this trunk is forwarded to. The host only: which number is dialed at that host comes from `destination_format`, because it changes with every call.
  - `priority` integer, required: The order gateways are tried in, lowest first. Gateways sharing a priority take an equal share of calls, and any of them may be tried first on a given call.
  - `origination_format` string, required: How the calling number is spelled to this gateway, as a template whose `{number}` stands for the number without its leading `+`. It is stated in the `P-Asserted-Identity` header of the delivered call. A gateway that has not asked for anything else reports `+{number}`, which is E.164. A format with no `{number}` states that same identity on every call, whoever called.
  - `destination_format` string, required: How this gateway formats the dialed number. In the template, `{number}` represents the number without its leading `+`. The result is placed before the `sip_uri` host. For example, `1234#{number}` formats `+31201234567` as `sip:1234#31201234567@pbx.example.com:5060`. A gateway that has not asked for anything else reports `+{number}`, which is E.164. A format with no `{number}` is dialed as it stands, so every number the trunk answers reaches that one number.
  - `created_at` string, date-time, required
  - `updated_at` string, date-time, required

## Other responses

- `400`: Bad request
- `401`: Authentication required
- `403`: Insufficient permissions
- `404`: Resource not found
- `422`: The request has invalid field values, violates a business rule, or carries a query parameter the endpoint does not declare. Field validation errors use `type: validation_error` and include the affected fields in `details`. Business-rule errors identify the failed rule in `type`.
- `429`: Rate limit exceeded
- `500`: Internal server error
