+Click to Call
+-------------
+
+**Click-to-Call** refers to the functionality of initiating calls automatically by clicking on a phone number. 
+The methods available depend on the chosen device:
+
+* **Web Phone**:
+   * Click-to-call is only possible within the **NethVoice CTI** web interface.
+
+* **Other Devices**:
+    To use click-to-call with devices other than the web phone, the `NethLink <https://nethserver.github.io/nethlink/>`_ client must be installed and configured on the user's system. Additionally, **NethLink** must be enabled for the user beforehand.   
+
+   1. **Desktop Phone** client provided by **NethLink**:
+     - Click-to-call can be performed directly in the **NethVoice CTI** web interface.
+     - On a Windows or Mac PC, **NethLink** can be set as the client for the `tel` or `callto` protocol, allowing it to handle phone numbers recognized by the operating system.
+   2. **Physical Phones**:
+     For physical phones supported and configured through **NethVoice** provisioning, click-to-call can only be performed if the client and the phone can communicate directly, such as when they are on the same local network or in two interconnected networks.
+     The click-to-call process in this configuration is identical to that of the **Desktop Phone** client:
+     - Click-to-call can be performed directly in the **NethVoice CTI** web interface.
+     - On a Windows or Mac PC, **NethLink** can be set as the client for the `tel` or `callto` protocol, allowing it to handle phone numbers recognized by the operating system.
