# ◾ Why are some of the buttons in the Intercom panel inactive?

The [**Intercom**](/doc/three-way-intercom-cSC64Vh1gB) feature requires certain technical setups to be completed. For the announcements to be sent, the relevant destination has to be physically connected and assigned within the software.


:::warning
***IMPORTANT:*** The **Intercom** functionality of LearningSpace requires the web browser to have **access to the microphone** of the client PC, which in turn requires a [**secure HTTPS**](/doc/how-to-use-the-https-certificate-requestupload-tool-jB97fG2coU) connection to the LearningSpace server.

That is, the **client computer's microphone can only be used** with a **valid SSL certificate**. (This restriction stems from the Chrome browser security regulations.)

* **Room**—The Room button sends announcements to the simulation area; therefore, a DAK (Digital Audio Kit) has to be connected and assigned to the Room (corresponding to the simulation area) via the Rooms tab of the System module as a **Separate In-room intercom device**.
* **Facilitator**—A device (e.g. headset) can be connected for direct communication with the facilitator. This device can be assigned to the room as a **Separate Hallway intercom device** via the **Rooms** tab of the **System** module.
* **Simulator** - a Maestro-ready simulator (with built-in speakers) can be connected and used for sending announcements through the manikin.  
    


:::info
**NOTE:** Once the simulator is connected, the Intercom is also connected for the manikin.

:::warning
The **Push-to-Talk** function of **Intercom** is **not supported on** [**iPads**](/doc/ipad-support-technical-information-iHec00YAzm) in LearningSpace.
