# Manually Register a Mitel IP Phone

When a Mitel IP phone isn't set up through auto-provisioning, you can register it by typing an extension's SIP (Session Initiation Protocol) credentials straight into the phone's web interface. The steps below use a Mitel 6867i running firmware 5.0.0.1018 as the example, but any Mitel phone that supports SIP follows the same process.

## Supported devices

Any Mitel IP phone that supports SIP.

## Before you start

You'll work in two places: first collect the extension's details from Cloud Voice, then enter them on the phone.

1. Gather the registration details from Cloud Voice.
2. Register the extension on the Mitel phone.

## Step 1. Collect the registration details from Cloud Voice

Sign in to the Cloud Voice management portal and note the values below. Keep them within reach for Step 2.

| Detail | Where to find it |
| --- | --- |
| Extension credentials | Go to **Extension and Trunk > Extension**, click the edit icon next to the extension, then open **User > Extension Information**. Record the **Extension Number**, **Caller ID**, **Registration Name**, and **Registration Password**. |
| Transport protocol | Go to **Extension and Trunk > Extension**, click the edit icon next to the extension, then open **Advanced > VoIP Settings > Transport**. Note which protocol the extension uses. This example uses **UDP** (User Datagram Protocol). |
| PBX domain name | The domain name of your Cloud Voice system. This example uses `pbx.example.com`. |
| SIP registration port | The SIP registration port is `5060`. |

The credentials you need are on the **Extension Information** tab:

The transport protocol lives under **Advanced > VoIP Settings**:

:::caution
The phone must use the same transport protocol as the extension. If the extension is set to anything other than UDP, confirm the matching listener is turned on before you register, or the phone won't connect:

- **TCP** (Transmission Control Protocol): enable the SIP TCP port at **PBX Settings > SIP Settings > General > Basic**.

- **TLS** (Transport Layer Security): enable TLS at **PBX Settings > SIP Settings > TLS**.

## Step 2. Register the extension on the Mitel phone

1. Log in to the phone's web interface.

   a. Enter the phone's IP address in your browser's address bar.

   b. Enter the username `admin` and its password. This example uses the default password `22222`.

   c. Click **Sign in**.

   :::note
   `22222` is the factory default admin password. If the phone was configured before, the password may have been changed, so use the site's current password instead.
   :::

2. In the left navigation bar, open **Advanced Settings** and choose an available line.

   :::note
   Each line is a separate SIP registration slot on the phone. Pick a line that isn't already in use so you don't overwrite an existing account.
   :::

3. Fill in the registration settings.

   a. In the **Basic SIP Authentication Settings** section, enter the extension credentials:

      - **Screen Name**: a name for the account; this appears on the phone's display.
      - **Phone Number**: the extension number.
      - **Caller ID**: optional; the extension's caller ID number, which shows on the called party's device.
      - **Authentication Name**: the extension's registration name.
      - **Password**: the extension's registration password.

      ![The Basic SIP Authentication Settings fields filled in on the Mitel phone](/images/pbx/mitel-sip-auth-setting.png)

   b. In the **Basic SIP Network Settings** section, enter the server details and set how often the phone re-registers:

      - **Proxy Server**: your Cloud Voice domain name.
      - **Proxy Port**: the SIP registration port.
      - **Registrar Server**: your Cloud Voice domain name.
      - **Registrar Port**: the SIP registration port.
      - **Registration Period**: optional; the interval, in seconds, between registrations.

      :::tip
      To see the allowed range for the registration period, check **PBX Settings > SIP Settings > General > SIP Endpoint Registration Timer** in the Cloud Voice portal.
      :::

4. Click **Save Settings**.

5. Reboot the phone to apply the changes.

   :::caution
   Rebooting takes the phone offline for a moment and ends any call in progress. Reboot when the phone is idle, or warn the user first.
   :::

## Result

The extension registers with Cloud Voice. To confirm, open **Status > System Information > SIP Status** in the phone's web interface.
