# SIP IpAccessControlList Resource

**IpAccessControlList** resources contain the Access Control List (ACL), which is a list of [**IpAddress** resources](/docs/voice/sip/api/sip-ipaddress-resource) that describe the IP addresses with access to the SIP Domain. Requests to the SIP Domain from an IP address that is not in the ACL are blocked.

After you create an **IpAccessControlList** resource, you will need to [map it to your SIP domain](/docs/voice/api/sip-interconnect) for it to take effect. You can apply the same list to more than one SIP Domain.

Your Account can have up to 1,000 **IpAccessControlList** resources. Each **IpAccessControlList** resource can contain up to 100 entries (which could be CIDR blocks).

## IpAccessControlList Properties

```json

```

## Create a SIP IpAccessControlList resource

`POST https://api.twilio.com/2010-04-01/Accounts/{AccountSid}/SIP/IpAccessControlLists.json`

The ACL that is created is empty and has no IP addresses.

You will need to add **IpAddress** resources to the list for it to have any effect.

### Path parameters

```json
[{"name":"AccountSid","in":"path","description":"The unique id of the [Account](/docs/iam/api/account) responsible for this resource.","schema":{"type":"string","minLength":34,"maxLength":34,"pattern":"^AC[0-9a-fA-F]{32}$"},"required":true}]
```

### Request body parameters

```json
