Use sipgate app in the mobile browser

How to use the sipgate app in the mobile browser on a smartphone or tablet – setup and limitations.

The sipgate app can also be used in the mobile browser – e.g. on a smartphone or tablet. Depending on the operating system and browser, there are differences, especially in the behavior of incoming calls (ringing, notifications) and microphone use.

iOS

The app generally works in Safari, Chrome and Firefox. For use in Safari additional settings are required, however, so that incoming calls ring and the microphone can be used permanently.

Allow microphone permanently (Safari)

1. Open the app in Safari:

2. Tap on the left in the address bar on aA or the website icon

3. Select Site settings

4. Set the microphone to Allow

Allow incoming calls to ring (Safari)

Open the iOS settings and click there on Safari.

About Advanced go to Feature Flags.

Enable there AudioSession Full API.

Note: This setting is required so that Safari emits a ringing signal for incoming calls.

Chrome on iOS

The app can be opened via Chrome on iOS. Incoming calls are, however, not signaled audibly, as iOS does not allow permanent audio playback in the background in these browsers.

Firefox on iOS

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

Android

The app works without restrictions. Incoming calls ring automatically – no additional settings required. This applies both to use in the browser and as an installed PWA (Progressive Web App).
