1. But I tried another version of this app for Android Oreo and it worked! So I decided to leave this comment - maybe it will help someone ;) I switched 'Receive Calls' on and 'Use SIP for Outgoing Calls' to 'For all Numbers'Worked great on Galaxy Tab A 8.0 2015.. Thanks Both incoming and outgoing calls.
2. much better than using standalone SIP client!!!Very useful app - enables VoiP/SIP calling via built-in phone app on Samsung phones.
3. Tried for Samsung Galaxy S20 FE 5G with Android 11 and it did not work.
4. The line kept ringing even when I hung up from my Phone app.Does not work on S9 with Android 10 but good app.
5. It will show you if it is compatible.Not working with Samsung Galaxy Note 8.
6. Works on Huawei P20 Pro as well!I was super happy until I did my first test.
7. Pls help to fix it.It has a problem.
