# Why am I no longer receiving calls in the sipgate app in the browser?

If you leave the sipgate app open in the browser in a background tab for a longer period of time, it can happen that you no longer receive any incoming calls. The connection to the app is interrupted and calls no longer get through.

#### How do I recognize the problem?

A red banner appears at the bottom of the app with the message **The connection could not be established** and a **Try again**button.

#### Solution

In your browser settings, you can make sure that the sipgate app is not paused automatically. This keeps the connection stable and you remain reachable at all times.

{% tabs %}
{% tab title="Google Chrome" %}

1. Open Chrome and enter *chrome://settings/performance* in the address bar

{% endtab %}

{% tab title="Microsoft Edge" %}

1. Open Edge and enter edge://settings/system in the address bar
2. Click on **Performance**
3. Find the section **Never put these websites into standby mode**
4. Click on **Add**
5. Enter <https://workspace.sipgate.com> enter it
6. Confirm with **Add**
   {% endtab %}

{% tab title="Mozilla Firefox" %}
**Option 1: Pin tab (only for the current session)**

* Right-click on the sipgate tab
* **Pin tab** select

{% hint style="info" %}
**Note:** This setting will be lost when you restart
{% endhint %}

**Option 2: Use extension (recommended)**

* Install the extension [**The Tab Suspender**](https://addons.mozilla.org/en-US/firefox/addon/the-tab-suspender/)
* Open the extension settings
* Add <https://workspace.sipgate.com> to the whitelist
  {% endtab %}

{% tab title="Safari" %}
Safari does not support exceptions for frozen tabs.\
**Our recommendation:** Use the [**sipgate app**](https://www.sipgate.de/app-download).
{% endtab %}
{% endtabs %}

#### Alternatives

**Separate browser window**

* Open the sipgate app in a separate window
* Leave this open, visible or minimized
* Do not open any other tabs in the same window

**Desktop app (recommended)**

The best solution is to use the sipgate desktop app, which is not affected by browser restrictions.

**Download:** [Download sipgate app](https://www.sipgate.de/app-download)

#### Immediate solution

If the problem has already occurred:

* Click on **Try again** in the red banner
* Wait until the connection is restored
* Set up one of the permanent solutions mentioned above

#### Background: Why does this happen?

Modern browsers automatically pause inactive tabs in order to:

* Save memory
* Improve system performance
* Reduce battery consumption

However, this disconnects the connection to the sipgate app, which prevents incoming calls.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://help.sipgate.de/cloud-telefonanlage/en/using-sipgate/die-sipgate-app/warum-erhalte-ich-keine-anrufe-mehr-in-der-sipgate-app-im-browser.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
