Using the sipgate app in a mobile browser
How to use the sipgate app in mobile browsers on iOS and Android, including PWA setup and troubleshooting.
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)
Open the app in Safari.
Tap aA or the website icon in the address bar.
Select Website Settings.
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)
Tap the Share icon.
Select Add to Home Screen.
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)
Tap the three dots in the top right corner.
Select Add to Home Screen.
Launch the app from the new icon.
