# Provision a Mitel DECT System with Cloud Voice

A DECT (Digital Enhanced Cordless Telecommunications) system has two parts: a base station and one or more DECT handsets. This guide covers provisioning a Mitel DECT base station with Cloud Voice, subscribing the handsets to that base station, and logging each handset in to an extension. When you finish, the handsets work like any other Cloud Voice extension and can place and receive calls.

## Requirements

Confirm that your Mitel base station firmware and Cloud Voice version meet the minimums below.

| Base Station | Base Station Firmware | Cloud Voice Version |
| --- | --- | --- |
| RFP 44 | 9.1 or later | 84.18.0.18 or later |
| RFP 45 | 9.1 or later | 84.18.0.18 or later |
| RFP 47 | 9.1 or later | 84.18.0.18 or later |
| RFP 48 | 9.1 or later | 84.18.0.18 or later |

:::note
For the full list of Mitel DECT handsets compatible with these base stations, see Mitel's product compatibility documentation.
:::

The examples in this guide use the following hardware and firmware:

| Component | Model | Firmware |
| --- | --- | --- |
| Mitel DECT base station | RFP 44 | v9.1 |
| Mitel DECT handset | 732d | v9.0.3.33 |

## Prerequisites

- The base station already has an IP (Internet Protocol) address configured, and you can reach its web interface at that address.
- You have the base station's Vendor, Model, and MAC (Media Access Control) address on hand. The MAC address is a unique hardware ID, usually printed on a label on the base station.
- You have downloaded the auto-provisioning template for the phone model you plan to use, available at **Auto Provisioning > Resource Repository > Default Templates**.

## Step 1. Add the base station in Cloud Voice

In the Cloud Voice management portal, register the base station, set its provisioning options, and assign extensions to the handsets.

:::note
Auto provisioning means Cloud Voice builds the configuration file for the base station and the base station downloads it automatically, so you do not have to type SIP account details into each device by hand.
:::

1. Sign in to the Cloud Voice management portal and go to **Auto Provisioning > Phones**.
2. Click **Add > Add**.
3. Under **IP Phone**, enter the device details.

   ![Adding a Mitel DECT base station with its vendor, model, and MAC address](/images/pbx/add-mitel-dect.png)

   - **Vendor**: Select **Mitel**.
   - **Model**: Select the base station model. This example uses **RFP 44**.
   - **MAC Address**: Enter the MAC address of the base station.
4. Under **Options**, configure the provisioning settings.

   
   ![Cloud Voice, provisioning options for the base station, including template and provisioning link](/images/pbx/mitel-dect-dhcp-option-cloud.png)

   - **Template**: Choose a template from the drop-down list. You can use the default template that matches the phone model, or build your own custom auto-provisioning template.
   - **Provisioning Link**: This link is generated for you and points to where the phone's configuration file is stored.

   :::note
   Write down the provisioning link. You will need it in Step 2.
   :::
5. Under **Assign Extension**, give each handset an extension. You can assign them one at a time or in bulk.

   To assign extensions individually:

   ![Assigning an extension to a single DECT handset](/images/pbx/assign-ext-to-handset-single.png)

   1. Select the checkbox next to the handset.
   2. Pick an extension from the **Extension** drop-down list.

   To assign extensions in bulk:

   ![Assigning a range of extensions to multiple handsets at once](/images/pbx/assign-ext-to-handset-bulk.png)

   1. Set a range using the **Start Extension** and **End Extension** fields.
   2. Click **Assign Extension**.

   :::tip
   If the extension you need is missing from the drop-down list, it is already tied to another IP phone. You can either release the extension from that phone, or enable concurrent registration for the extension so it can register with more than one SIP (Session Initiation Protocol) endpoint. By default, an extension registers with only a single endpoint.
   :::
6. Under **Preference**, choose a time zone from the **Time Zone** drop-down list.
7. **Optional**: Adjust any other settings you need.
8. Click **Save**.

## Step 2. Set the provisioning URL on the base station

Enter the provisioning link from Cloud Voice into the Mitel base station manually.

1. Log in to the base station's web interface.

   
   ![Cloud Voice, login page of the Mitel DECT base station web interface](/images/pbx/mitel-dect-gui.png)

   1. Enter the base station's IP address in your browser's address bar.
   2. Enter the username and its password.
   3. Click **OK**.
2. On the top menu, select the **Advanced** checkbox to reveal the advanced settings.

   ![Enabling the Advanced checkbox to show advanced settings on the base station](/images/pbx/mitel-dect-enable-advanced-settings.png)
3. In the left navigation bar, go to **System > Provisioning & Software Update**.
4. In the **Provisioning URL** section, do the following:

   1. Select the **Active** checkbox.
   2. Fill in the fields below using the provisioning link you noted in Step 1.

      
      ![Cloud Voice, entering the provisioning URL details on the base station](/images/pbx/mitel-dect-prov-link-cloud.png)

      - **Protocol**: Select **HTTP** or **HTTPS**, matching the prefix of the link.
      - **Server**: Enter the server address (IP address or domain name).
      - **Port**: Enter the server port.
      - **Path**: Enter the file path, for example `api/autoprovision/6gEzigLFhMGntjd8`.

      :::caution
      The Protocol, Server, Port, and Path together must recreate the provisioning link from Step 1 exactly. If any one part is wrong, the base station cannot reach Cloud Voice and provisioning silently fails.
      :::
5. At the top of the page, click **OK**.
6. Go to **System > System Settings**, then click **Restart** and **OK** to start provisioning.

   :::caution
   Restarting reboots the base station. Any handsets registered to it lose service while it reboots, so calls in progress will drop. On a live system, restart during a maintenance window.
   :::

   ![Restarting the base station to trigger provisioning](/images/pbx/mitel-dect-restart.png)

   After the base station restarts, wait a few minutes. When a green check ![Green check icon](/images/pbx/green-check.png) appears for it at **SIP Users/Devices > Subscription**, the base station has downloaded its configuration file from Cloud Voice.

   ![Subscription page showing the base station has downloaded its configuration](/images/pbx/mitel-dect-subscription.png)
7. Go to **SIP Users/Devices > General > DECT authentication code**, set an authentication code, and write it down. You will enter this code when subscribing the handset in Step 3.

   ![Setting the DECT authentication code on the base station](/images/pbx/mitel-dect-auth-code.png)

## Step 3. Subscribe and log in a handset

Subscribe the handset to the base station, then log it in to its assigned extension.

1. Subscribe the handset to the base station.

   1. On the handset, go to the More options icon ![More options icon](/images/pbx/more-horiz.png) **> System > Subscription**.

      The handset searches for a base station. When it finds one, it prompts you for an authentication code.
   2. Enter the authentication code you set in Step 2, then press **Next** and **Ok**.

      The handset shows "success", confirming it is subscribed to the base station.
2. Log in to the handset.

   1. On the handset, press **Log in**.
   2. On the **Number** page, enter the extension number assigned to the handset, then press **Ok**.
   3. On the **User login** page, enter the extension number again, then press **Ok**.

## Result

The handset is now subscribed to the base station and, through it, associated with its assigned Cloud Voice extension.

- In the base station web interface, you can check the handset's subscription status at **SIP Users/Devices > SIP user**.

  ![Base station SIP user list showing the subscribed handset](/images/pbx/mitel-dect-handset-on-base.png)
- In the Cloud Voice management portal, you can check the extension's registration status at **Auto Provisioning > Phones**.

The registered handsets can now be used as Cloud Voice extensions to make and receive calls.
