1. Other than that, it works.I am not happy anymore with Linephone Android app! - After the recent few updates of Linephone, it doesn't work well with FreePhoneLine.ca SIP Credential anymore! - When I make a call, the app Sound quality is OK, but Most of the times when someone calls me, the phone doesn't ring and it goes to voice message without ringing! - I have given all the permissions to the Linephone app too! - I believe the Linephone app is not able to wake-up my Sam Note 20 from sleep anymore!Drops received call after a few seconds (does not happen with the same account and provider using a different client on the same phone.)Early UI was a little clumsy, but since version 4 Lin is a great app and amazing service.It sucks, I tried over 7 times to get the verification code to my phone, but I couldn't get it.
2. If you can manage to get the app to dial the correct number and connect then call quality is good.I would like to see the media encryption under Call to be moved to individual profile as not all service providers support media encryption.
3. Some issues I noticed is that audio gets very distorted when other notifications are displayed on the Android phone.
4. I checked everything, the phone number, the internet connection,the permissions, everything without a benefit.Worked on one phone but not on the other.
5. If I activate the background mode to leave a permanent notification on the screen, it receives calls, but kills the battery quickly.
6. Also to make switching profile more easily.Seems perfectly functional except cannot access text message history except by notification of incoming messages.
7. There is an echo when setting up a conference call and you can't easily switch to other accounts if configured.
8. Including corrupting contacts (dials a different number from the one in the contact, can only be fixed by wiping the app and reinstalling).
9. But when the screen goes to sleep, the app does not receive calls reliably.
10. It works fine so long as the phone is awake.
11. This is distracting as you can't hear the other party until the notification ends.
