# Using the sipgate app in a mobile browser

You can use the sipgate App in a mobile browser - on your smartphone or tablet.\
Depending on your operating system and browser, there may be differences, especially in how incoming calls ring, how notifications appear, and how the microphone is accessed.

#### iOS: Safari, Chrome, and Firefox

The app works in all three browsers. However, Safari requires extra settings so that **incoming calls ring** and **the microphone** can be used continuously

#### **Allow Microphone Access (Safari)**

1. Open the app in Safari.
2. Tap **aA** or the website icon in the address bar.
3. Select **Website Settings**.
4. Set **Microphone** to **Allow**.

#### **Enable Ringing for Incoming Calls (Safari)**

Go to the **iOS Settings** app and select **Safari**.

Under **Advanced**, open **Feature Flags**.

Enable **AudioSession Full API**.

**Note:** This setting is required for Safari to play a ringtone for incoming calls.

#### **Chrome on iOS**

You can open and use the app, but incoming calls will not ring. iOS does not allow continuous background audio in these browsers.

**Firefox on iOS**

The app works without restrictions. Incoming calls ring automatically—no additional settings are required.

#### Android: Chrome, Firefox and Samsung Internet

The app works without restrictions. Incoming calls ring automatically—no additional settings are required.\
This applies both in the browser and if you install the app as a **Progressive Web App (PWA)**.

#### Adding the App to Your Home Screen (PWA)

Installing the app as a PWA gives you faster access. This is optional but recommended.

**iOS (Safari)**

1. Open: <https://workspace.sipgate.com>
2. Tap the **Share** icon.
3. Select **Add to Home Screen**.
4. Launch the app from the new icon.

**Important:** For incoming calls to ring, the **AudioSession Full API** feature (see **Enable Ringing for Incoming Calls Safari**) must be enabled.

**Android (Chrome)**

1. Open: <https://workspace.sipgate.com>
2. Tap the three dots in the top right corner.
3. Select **Add to Home Screen**.
4. Launch the app from the new icon.
