# Provision Grandstream ATA Devices to Dialpad

Grandstream Analog Telephone Adapters (ATAs) are compact devices that connect traditional landline phones to internet-based phone systems (VoIP networks), such as Dialpad, providing the benefits of digital communication without requiring device replacement.

Let’s set up your ATA device.

> [!NOTE]
> Who can use this
> 
> ATA devices can be used on [any Dialpad plan](https://www.dialpad.com/pricing/).

## Supported Grandstream models

To determine which Grandstream models are supported by Dialpad, refer to this [Help Center article](/v1/docs/supported-desk-and-room-phones#atas).

> [!NOTE]
> Note
> 
> If you purchased your Grandstream ATA device directly from Dialpad, you don’t need to provision the phone, as it’s already provisioned for Dialpad. Go to the [Add the ATA to the Dialpad Admin Portal](/v1/docs/provision-grandstream-ata-devices-to-dialpad#add-the-ata-to-the-dialpad-admin-portal) section below to set up your Grandstream ATA device.

## Deskphone admin password

Company admins can access their organization’s deskphone password directly from the Company Settings. This admin password applies to all deskphones activated with Dialpad.

To access the deskphone admin password, go to your Dialpad **Admin Portal.**

1. Select **My Company >** **Deskphone Settings** ![The My Company admin settings page for the deskphone admin password.](https://cdn.us.document360.io/0f28ad44-2863-4372-a27e-c6728808d742/Images/Documentation/Deskphone Admin Password.png)
2. Navigate to **Deskphone Admin Password**and select the eye icon to see the password

Then, log in to the deskphone's web interface using **‘admin’** as your username and your assigned deskphone admin password.

> [!NOTE]
> Note
> 
> The deskphone admin password cannot be changed.

## Set up process

Setting up your Grandstream ATA device with Dialpad is a 4-step process.

1. Factory reset the ATA device
2. Provision the ATA device to Dialpad
3. Add the ATA device to the Dialpad Admin Portal
4. Activate (assign) the port for a Dialpad user or room

## Factory reset

Now, we need to perform a factory reset to ensure that any previous configuration data has been removed and will not interfere with your Dialpad service.

There are three ways to factory reset your Grandstream devices:

### Factory reset via the reset button

To reset to factory default settings using the reset button:

1. Unplug the Ethernet cable
2. Locate the reset hole on the back panel of your HT812/HT814
3. Insert a physical pin into the pin hole
4. Press for ~**7 seconds**
5. Take out the pin

All device settings will be restored to their factory settings.

### Factory reset via IVR command

To reset factory settings using the IVR prompt:

1. Dial ******* on the phone
2. Enter **99** on the keypad
3. Wait for the **Reset** voice prompt
4. Enter the encoded Device MAC address
  1. Follow the guide below on how to encode the Device MAC address.

Wait for 15 seconds, and the device will automatically reboot and restore to its factory settings.

#### To encode the Device MAC Address:

1. Locate the Device's MAC address

> [!TIP]
> Tip
> 
> The 12-digit HEX number is located at the bottom of the unit.
2. Enter the Device MAC address using the following mapping:

| Key | Mapping |
| --- | --- |
| 0-9 | 0-9 |
| A | 22 (press the “2” key twice, “A” will show on the LCD) |
| B | 222 |
| C | 2222 |
| D | 33 (press the “3” key twice, “D” will show on the LCD) |
| E | 333 |
| F | 3333 |

For example, if the Device MAC address is 000b8200e395, it should be keyed in as “0002228200333395”.

> [!NOTE]
> Note
> 
> Grandstream ATAs have two MAC addresses: one for the **LAN** and one for the **WAN**. Ensure that you enter the **LAN** address, listed as the Device's MAC address.

### Factory reset via web interface

To reset factory settings using the web interface:

1. Connect the device to the internet

  1. Plug the Ethernet cable into the ATA device
  2. Plug the phone cable into an analog phone
2. Locate the IP address of the phone
  1. Dial *******
  2. Dial **02**
  3. Wait for the IVR to read out the device’s IP address
  4. Note the device’s IP address
3. Enter the IP address in a web browser

## Frequently asked questions (FAQ)

### Why is there a pause before my ATA phone call goes through?

When you make a call with your ATA device using VoIP, there’s usually a 4-second delay after you dial a number. Since VoIP calls go over the internet, the process is more complex than with regular phone lines, which causes this delay.
