# How do I configure the BLF function for Grandstream?

We have tested the BLF function with the following Grandstream models:

* GXP 2110 and GXP 2120
* GXP 2020
* GXP 2124

{% hint style="info" %}
Please note that this function is only available if you have booked the **sipgate business L or XL** plan.
{% endhint %}

#### GXP 2110 and GXP 2120

{% hint style="warning" %}
**Important**: Using the BLF speed-dial key, the pickup function (picking up calls) is not possible with these models.
{% endhint %}

**Login**

To access the configuration interface of the Grandstream phone, you first need the IP address assigned to the phone.

On many Grandstream models, the IP address is shown directly on the display; otherwise, you can find it by pressing the key **Menu** on the phone and then selecting **Status** ➔ **Network Status ➔** **IP** . You will now see the assigned IP address (e.g. 192.168.0.5).

**Create user for the BLF**

Enter the IP address in your browser’s address bar. You will now see the configuration interface of your phone. If you received the GXP 2110/2120 unconfigured, the password is **admin**. Use the menu to go to **settings** ➔ **Programmable Keys**. In the following window, you can enter the data as shown below.

Select from the list of multifunction keys in the field **Mode** please **Busy Lamp Field (BLF)** . To the right of that, select your own sipgate account (in this example, account 1). In the field **Description** enter, for example, the name of the user. In the field **Value** enter the user’s extension. So, for example, enter "42" to see the status of the user with extension 42. Confirm your entries by clicking **Save and apply**. Often the settings are only fully applied after you then reboot the phone (click Restart in the top right next to the language selection).

#### GXP 2020

**Display phone IP address**

Please make sure that DHCP is enabled on the router. On most routers, DHCP is enabled by default. Connect the Grandstream phone to your router with a network cable. The Grandstream phone will be assigned an IP address by the router. In most cases, the IP address will then already be shown on the phone’s display.

If this is not the case: press the **Menu** key on the phone. Then press **Config** ➔ **Network** ➔ **IP.** The current IP address is displayed. If 0.0.0.0 is shown, please check point 1 and restart the router and phone.

If the IP address is, for example, "192.168.001.100", please enter it in your browser without leading zeros: "<http://192.168.1.100>". You will now be taken to the Grandstream phone’s web configuration menu.

**Create user for the BLF**

Enter the IP address in the address bar of your browser. You will now see your phone's configuration interface.

{% hint style="info" %}
**Important:** If you received the GXP-2020 unconfigured, the password is **admin**.
{% endhint %}

Use the menu to go to **Basic Settings**. In the following window, you can enter the data as shown below.

In the field **Name** enter, for example, the name of the user. In the field **UserID** enter the user’s extension. So, for example, enter "42" to see the status of the user with extension 42. Confirm your entries by clicking **Update**.
