# Update SIP Trunk

Update a SIP trunk's configuration. All fields are optional — only fields you send are updated. Changes that affect connectivity (domain, transport, credentials) automatically reset `is_verified` to `false`.

## Endpoint

```
PUT /api/v1/sip-trunks/{trunk_id}
```

## Path parameters

<ParamField path="trunk_id" type="string" required>SIP trunk UUID.</ParamField>

## Request headers

<ParamField header="Authorization" type="string" required>
  Bearer token. Format: `Bearer talq_your_environment_token_here`
</ParamField>

<ParamField header="Content-Type" type="string" required>
  Must be set to `application/json`
</ParamField>

## Request body

Same fields as [Create SIP Trunk](/api-reference/endpoints/create-sip-trunk), all optional.

## Examples

  ```bash theme={null}
  curl -X PUT "https://app.talkover.ai/api/v1/sip-trunks/trunk-uuid-1" \
    -H "Authorization: Bearer talq_your_environment_token_here" \
    -H "Content-Type: application/json" \
    -d '{
      "name": "Primary Carrier — US (renamed)",
      "is_active": false
    }'
  ```
</RequestExample>

  ```json theme={null}
  {
    "success": true,
    "data": {

      "name": "Primary Carrier — US (renamed)",
      "is_active": false,
