To receive incoming VoIP and business calls reliably, the Mobyx softphone must be allowed to receive push notifications and operate correctly in the background. Android and iPhone handle background apps differently, so the required settings vary by device.

Mobyx softphone app running in the background so you never miss incoming business or VoIP calls, you need to prevent your phone's operating system from putting the app to sleep. 

First, ensure that Push Notifications are active inside Mobyx: Open Mobyx ➔ tap the three dots (More) ➔ Settings ➔ ensure Incoming Calls is set to "Use Push Notifications". 

Depending on your mobile device, apply the system settings below:

For Android Devices

Android devices aggressively close background apps to save battery life. Change these settings to keep Mobyx alive: 

1. Remove Battery Restrictions

• Open your phone's Settings ➔ Apps (or App Management).
• Select Mobyx from the list.
• Tap on Battery (or App Battery Usage).
• Switch the setting from Optimized to Unrestricted. 

• While still in the Mobyx app settings, tap Mobile Data (or Data Usage).
• Toggle on Allow background data usage.
• Turn on Allow data usage when Data Saver is on to ensure it still works in low-data modes. 

• Swipe up to open your recent/open apps screen.
• Press and hold the Mobyx icon or tap the options menu above the app window.
• Select Lock this app (a padlock icon will appear), which prevents the system from closing it when you clear your background tasks.

For Apple iOS (iPhone)

iOS handles background apps natively via Apple's proprietary push network, but you must grant the proper permissions:

1. Go to Settings ➔ General ➔ Background App Refresh.
2. Make sure Background App Refresh is toggled On (ideally set to Wi-Fi & Mobile Data).
3. Scroll down the list of apps and verify that the toggle next to Mobyx is turned On.
4. Go back to main Settings ➔ Notifications ➔ Mobyx ➔ Ensure Allow Notifications, Sounds, and Badges are completely turned on.
