# How to place an outbound PSTN call

Learn how to place outbound PSTN calls from DoubleTick’s Web and Android apps.

Once your PSTN channel is set up and your agents have the right access, you're ready to start making calls. A PSTN call is placed from within an existing WhatsApp conversation on DoubleTick, and it can be handled either by a human agent or by your AI Agent, depending on how you choose to route it. This guide walks you through placing an outbound call from both the Web app and the Android app, and what happens once it connects.

#### How to place an outbound PSTN call (Web app)

Make sure you know which WhatsApp channel your PSTN number is linked to, then open or start a conversation with the customer on that channel and click the **call icon**. Under **Mode of calling**, you'll see two options — **WhatsApp Call** and **PSTN Call**. Select **PSTN Call**, then choose the PSTN number you want to call from. From here, both Manual and AI PSTN calls are supported.

* **Open** the DoubleTick Android app and **go to** Chats.
* **Open** the customer's chat, or start a new one using their phone number.
* **Click** the **Call** icon in the top-right corner.

* **Select** the PSTN number you want to use.
* Under **Call type**, **select** AI.
* **Select** the AI Voice Agent you want to use from the dropdown.
* **Click Call Now.**

The selected AI Voice Agent will place the PSTN call to the customer.

#### What happens once the call is placed

The call flow depends on whether you are placing a **manual PSTN call** or an **AI call**.

**Manual PSTN call**:\
When you place a manual PSTN call from the **Web app or Android app**, the agent who triggers the call first receives a call on their registered phone number. Once the agent answers, DoubleTick automatically places a second call to the customer's phone number. When the customer answers, both calls are connected, and the agent and customer can start the conversation. After the call ends, DoubleTick generates the **call transcript and summary**, provided the **AI Suite add-on** is purchased for your account.

**AI call**:\
When you place an AI call from the **Web app or Android app**, the AI agent directly places a call to the customer's phone number. Once the customer answers, the AI agent starts the conversation. After the call ends, DoubleTick generates the **call transcript and summary**, provided the **AI Suite add-on** is purchased for your account.

#### Key takeaways

* You can place outbound PSTN calls from either the DoubleTick Web app or the Android app.
* Both apps support Manual Call (a human agent) and AI Call (your AI Agent handles it automatically).
* Calls can only be placed from a conversation on the WhatsApp channel linked to your PSTN number.
* Once a call ends, the recording, transcript, and summary are captured automatically inside the conversation.
