# Door-opening Configuration

## Unlock by Public PIN Code

There are two types of PIN codes for door access: public and private. A private PIN is unique to each user, while the public one is shared by residents in the same building or complex. You can create and modify both the public and private PIN codes.

To set up the public PIN code, go to **Intercom > PIN Setting > Public PIN** interface.

## Unlock by DTMF Code

Dual-tone multi-frequency signaling(**DTMF**) is a way of sending signals over phone lines by using different voice-frequency bands. Users can use the DTMF function to unlock the door for visitors during a call by either typing the DTMF code on the soft keypad, or tapping the unlock tab with the DTMF code on the screen.

To configure DTMF codes, go to **Intercom > Relay** interface.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-BCJM6XCU.png)

- **DTMF Mode**: Set the number of digits for the DTMF code.
- **1 Digit DTMF**: Define the 1-digit DTMF code within the range(0-9 and *,#) when the DTMF Mode is set to 1-digit.
- **2-4 Digit DTMF**: Set the DTMF code based on the number of digits selected in the DTMF Mode.

> [!NOTE]
> Note
> 
> To open the door with DTMF, the intercom devices that send and receive the unlock command must use the same mode and code. Otherwise, the DTMF unlock may fail. See [here](https://knowledge.akuvox.com/docs/how-to-open-the-door-via-dtmf-on-the-indoor-monitor) for the detailed DTMF configuration steps.

### DTMF White List

To secure door access via DTMF codes, you can set up the DTMF whitelist on the device web **Intercom > Relay >** **Open Relay Via DTMF** interface so that only the caller numbers you designated in the door phone can use the DTMF code to gain door access.

![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-XA0B9CIM.png)

- **Assigned The Authority For**: Specify the contacts authorized to open doors via DTMF:
  - **None**: No numbers can unlock doors using DTMF.
  - **Only Contacts List**: Doors can be opened by numbers added to the door phone's [contact list](/v1/docs/contact-list-configuration-2).
  - **All Numbers**: Any numbers can unlock using DTMF.

### DTMF Data Transmission

In order to achieve door access via DTMF code or some other applications, you are required to properly configure DTMF in order to establish a DTMF-based data transmission between the device and other intercom devices.

**DTMF Type Differences**:

| Inband | DTMF signals are transmitted within the same audio channel as voice data. Simple implementation but signal distortion may occur with highly compressed codecs (e.g., G.729). |
| --- | --- |
| RFC2833 | Transmits DTMF as special event packets over RTP (Real-Time Transport Protocol), known as out-of-band transmission. Reliable and unaffected by codecs. |
| Info | Sends DTMF signals via SIP (Session Initiation Protocol) signaling channel. Separate from voice transmission, ensuring audio quality. |
| Info+Inband | Combines Info and Inband methods. |
| Info+RFC2833 | Combines both Info and RFC2833 methods. |
| Info+Inband+RFC2833 | All three methods are used simultaneously. |

Set it up on the **Account > Advanced > DTMF** interface. ![](https://cdn.document360.io/f09a6106-e976-455e-b2d0-3d88b5385960/Images/Documentation/image-XE9R13XK.png)

- **Type:** Select from the following options: **Inband, RFC2833, Info, Info+Inband, Info+RFC2833,** or **Info+Inband+RFC2833** based on the specific DTMF transmission type of the third-party device to be matched with as the party for receiving signal data.
- **How to Notify DTMF**: Select **Disabled, DTMF, DTMF-Relay**, or **Telephone-Event** according to the specific type adopted by the third-party device. You are required to set it up only when the third-party device to be matched with adopts **Info** mode.
- **Payload**: Set the payload according to the specific data transmission payload agreed on between the sender and receiver during the data transmission.

## Unlock by Exit Button

When users need to open the door from inside by pressing the Exit button, you need to set up the Input terminal that matches the Exit button to activate the relay for the door access.
