# Make Your First Call with TD52

The [Verkada TD52 Video Intercom](https://www.verkada.com/intercom/td52/) enables you to effortlessly make calls to receivers. The [Verkada Command dashboard](https://command.verkada.com/intercoms) allows for different configurations to complete calls, such as through a phone number, through a desk station, and directly to a user (through the [Verkada Pass App](https://app.gitbook.com/s/aaHs5RfKqv9Z49mi02cC/configuration-and-setup/verkada-pass-app)).

### Before you begin

#### The intercom must be plugged into a Power over Ethernet (PoE)-enabled switch.

{% endstep %}

{% step %}

#### A door must be paired to the intercom.

{% endstep %}

## Receive a call

When a call is made from the intercom, it is sent to a [desk station](#h_3b3485af68), a [user](#h_52f240d4e5), a [phone number](#h_1d91b1bfab), or a [SIP phone](#h_ea6bdfd96d).

### Desk station

The desk station can be a tablet that runs the Intercom app. It acts as a live view receiver and is always on. This type of receiver is typically used at a desk or reception environment. Learn how to [add a desk station](https://help.verkada.com/intercom/configuration-and-setup/add-a-desk-station).

**How it works**

{% stepper %}
{% step %}

#### When a call is made to a front desk station, the person watching the tablet can see the caller on screen and has the option to speak to and unlock the door for the caller.

{% endstep %}

{% step %}

#### Once the station is setup, you can add up to 4 tiles. A persistent live stream from the intercom camera is displayed along with an **unlock** icon. You can easily unlock the paired door anytime before or during a call made to the desk station.

{% endstep %}

{% step %}

#### Once a call has started, the receiver has the option to unlock the door or end the call at any point during the call.

{% endstep %}
{% endstepper %}

### User

A user is any granted-access user in your organization and who has access to Verkada Command.

**How it works**

{% stepper %}
{% step %}

#### When a call is made, the user receives a call to their [Verkada Pass App](https://app.gitbook.com/s/aaHs5RfKqv9Z49mi02cC/configuration-and-setup/verkada-pass-app).

{% endstep %}

{% step %}

#### Once a call is made, then the receiver can see the caller and has the option to unlock the door, speak through the pass app, and end the call at any time.

{% endstep %}
{% endstepper %}

### Phone number

A phone number allows a caller to reach someone via a phone call. A phone number can be any standard mobile or landline phone number. You can add international phone numbers using the appropriate international identifier, or you can select the correct country at the time the receiver is added.

Both SIP and regular phone numbers have the option to toggle ’press # or \* to accept the call.

**How it works**

{% stepper %}
{% step %}

#### When a call is initiated from the Intercom to a phone number, the receiver receives a call from a standard number.

{% endstep %}

{% step %}

#### When the phone call is answered, the call from the Intercom has not yet started, and the call will start when an asterisk (\*) or hashtag (#).

{% endstep %}

{% step %}

#### The receiver can accept the call and has the option to speak to the caller and unlock the door using any digits (0–9).

{% endstep %}
{% endstepper %}

You can find information about answering a call and the phone number where an Intercom initiates a call from the **Settings** page.

### SIP phone

You can have the Intercom call a Session Initiation Protocol (SIP) extension. Learn more about [SIP](https://help.verkada.com/intercom/configuration-and-setup/integrate-verkada-intercoms-with-sip).

**How it works**

{% stepper %}
{% step %}

#### When a call is initiated from the Intercom to a phone number, the receiver receives a call from a standard number.

{% endstep %}

{% step %}

#### When the phone call is answered, the call from the Intercom has not yet started, and the call will start when an asterisk (\*) or hashtag (#).

{% endstep %}

{% step %}

#### The receiver can accept the call and has the option to speak to the caller and unlock the door using any digits (0–9).

{% endstep %}
{% endstepper %}
