# How to configure the BLF with Tiptel

#### Prerequisites

Before programming the Busy Lamp Field (BLF) keys, ensure the following:

Assign internal extensions to all users in your sipgate account via the web interface. These internal sipgate numbers are required to configure the BLF keys. The Tiptel IP phone must be registered with sipgate.

#### Configuration Steps

1. Log in to the Tiptel web interface and navigate to **Keys -> Function Keys**.
2. Configure the desired keys with the following settings:
   * **Key Type:** Set to "Busy Lamp Field (BLF)".
   * **Label Text:** Choose a custom label for the key.
   * **Parameter 1:** Enter the internal sipgate extension, e.g., 10
   * **Account:** Select the corresponding sipgate account.
   * **Parameter 2:** Enter the sipgate pickup code: \*9+extension. For example, for extension 10, enter \*910.

### Example

In this setup, extensions 10, 11 and 12 are assigned as BLF keys:

* BLF Key 1: Parameter 1 = 10, Parameter 2 = \*910
* BLF Key 2: Parameter 1 = 11, Parameter 2 = \*911
* BLF Key 3: Parameter 1 = 12, Parameter 2 = \*912

### Understanding the Status

* **Green Light:** The extension is free.
* **Blinking Red Light:** The extension is receiving a call.
* **Solid Red Light:** The extension is on a call.
