# Manually Register an Akuvox Intercom Device with Cloud Voice

Cloud Voice can manage Akuvox intercom hardware as ordinary SIP (Session Initiation Protocol, the standard that carries voice calls over the network) endpoints. This page walks through registering an extension on an Akuvox door phone and indoor monitor manually, using the Akuvox E16C V2.0 as the reference model. Once each device holds a registered extension, the PBX (Private Branch Exchange, your phone system) routes a door-phone call straight to the indoor monitor, letting the extension user pick up and release the door lock from a distance.

:::note
Extensions cannot be registered on the Akuvox X915S or X912K door phones.

## Before you begin

**Intercom device**

- Confirm the device speaks SIP.
- If the unit was in service before, reset it to factory defaults first.
- Give the device a valid IP (Internet Protocol) address, either from DHCP (Dynamic Host Configuration Protocol, automatic addressing) or a static assignment.

:::caution
A factory reset erases everything on the device, including its network settings and any saved SIP accounts. Only reset a unit that was previously in service, and write down any settings you need to keep before you start.
:::

**Local computer**

- Install the Akuvox IP Scanner on a computer that sits on the same subnet as the intercom device. The tool is available from Akuvox's documentation site.

:::note
The IP Scanner finds devices by broadcasting across the local network, so it can only see units on the same subnet as your computer. This is why the computer and the intercom device must share a subnet.
:::

**Cloud Voice**

- Note the credentials for the SIP extension you plan to assign to the device: the extension number, registration name, and registration password. You'll find these under **Extension and Trunk > Extension > Extension Information**.

## Register the extension

1. Find the IP address of the Akuvox device.
   1. Launch the Akuvox IP Scanner.
   2. Click **Refresh** on the toolbar.

      The detected device appears in the list together with its IP address.

      :::tip
      If nothing shows up, confirm the device is powered on and on the same subnet as your computer, then click **Refresh** again.
      :::

2. Open the device's web interface.
   1. Type the device's IP address into your browser's address bar.
   2. Enter the username and password, then click **Login**.

      :::note
      Both the default username and password are `admin`.
      :::

3. Navigate to **Account > Basic**.

4. Under **SIP Account**, fill in the following fields.

   ![Akuvox SIP Account settings with the account enabled and extension credentials entered](/images/pbx/manually-register-add-account.png)

   - **Account Enabled**: Select the checkbox to turn the SIP account on.
   - **Register Name**: Enter the extension's registration name.
   - **Username**: Enter the extension number.
   - **Password**: Enter the registration password.

   :::caution
   On Akuvox devices the **Username** field takes the extension *number*, while **Register Name** takes the registration name from the PBX. Swapping these two values is the most common reason registration fails, so double-check them before submitting.
   :::

5. Scroll to **Preferred SIP Server** and enter your PBX's domain name in the **Server Address** field.

   :::note
   Use the PBX's domain name here rather than a raw IP address. The domain name keeps working even if the PBX's underlying IP address changes.
   :::

6. Click **Submit** at the bottom of the page.

## Result

The extension is now registered on the intercom device. To confirm, open **Extension and Trunk > Extension > Online Status** in the PBX web portal, where the endpoint shows a registered SIP status ![Registered SIP endpoint status icon](/images/pbx/SIP.png) indicator.
