# Monitor a Parking Number on an IP Phone

When a team relies on directed call parking, you can give each user a dedicated function key that both shows the live status of a parking number and lets them park or retrieve a call from it in a single press. You assign these keys centrally through auto provisioning, then push them to the phone.

:::note
- Users can also program function keys directly on their own phones. Refer to the phone manufacturer's documentation for those steps.
- Once a key is in place, any agent can press it to park or retrieve a call.
:::

## Before you begin

The phone must already be connected to the PBX (Private Branch Exchange, the phone system that routes your calls) and linked to the user's extension through auto provisioning. If you haven't done that yet, set it up first:

- [Auto Provision IP Phones Remotely via RPS Method](/pbx/administrator-guide/auto-provision-ip-phones-remotely-rps-method/)
- [Auto Provision IP Phones Remotely with Proxy](/pbx/administrator-guide/auto-provision-ip-phones-remotely-with-proxy/)

For background on how central provisioning works, see [Auto Provisioning Overview](/pbx/administrator-guide/auto-provisioning-overview/).

## Assign the function key

1. Sign in to the PBX web portal and go to **Extension and Trunk > Extension**.
2. Open the extension you want to configure:
   - For a single user, click the edit icon ![Edit an extension](/images/pbx/edit.png) next to that extension.
   - For several users at once, select their checkboxes and click **Edit**.
3. Open the **Function Keys** tab.
4. Define the key:
   - **Type**: choose **Park & Retrieve**.
   - **Value**: choose the parking number to monitor.
   - **Label**: optional text that appears next to the key on the phone screen.
5. Click **Save**.

:::tip
If a user monitors more than one parking number, give each key a short, distinct **Label** such as "Park 1" or "Sales Park". A clear label lets the user tell the keys apart at a glance.
:::

:::caution
The count of programmable keys differs from one phone model to another. If you assign more function keys than the phone supports, the extra keys are ignored.

## Push the change to the phone

If the extension is already tied to a phone, reprovision it so the new key takes effect:

1. Go to **Auto Provisioning > Phones**.
2. Click the refresh icon ![Reprovision the phone](/images/pbx/refresh.png) next to the phone assigned to that extension.

## What the user sees

The key reflects the parking number's state in real time through its LED:

- **Green**: the parking number is free. The user can press the key to park an active call there.
- **Red**: the parking number is in use. The user can press the key to retrieve the parked call.

:::note
Exact LED behavior can differ depending on the phone model.
