Best Softphones for Android Devices
The best SIP apps for Android phones and tablets, plus battery optimization tips to keep calls ringing in the background.
By HelloPBX Team · April 28, 2026
Android offers more background flexibility than iOS, but aggressive battery savers from manufacturers like Samsung, Xiaomi, and OnePlus can still kill incoming calls. Here are the softphones we trust on Android and how to keep them reliable.
Our top picks for Android
- Zoiper — consistent performer with a clean dialer and broad codec support.
- Linphone — free and open source with strong encryption support.
- Bria Mobile — business-grade features and excellent call handling.
- MizuDroid — lightweight and free, good for basic SIP registration.
Stop Android from killing your calls
- 1Open Settings → Apps → your softphone → Battery, and set it to Unrestricted.
- 2Disable battery optimization for the app so it can run in the background.
- 3On Xiaomi/MIUI, enable Autostart for the app.
- 4Keep the app's built-in push or keep-alive enabled to maintain registration.
If calls only ring when the app is open, battery optimization is almost always the culprit. Set the app to Unrestricted first.
