Trouble with using audio on VoLTE calls

[vapid-88]

Hello Phhusson,

First off, many thanks for your development on the open source telephony stack and floss ims!

I’m having issues using it with my galaxy S21 FE, I read through the GitHub issues for it and saw that other users are encountering similar errors such as not being able to be heard on the receiving end of the call. For basic troubleshooting, I began by testing outgoing calls. Even when the other person answered, the call state on my phone indicating “dialing” I could still hear the other person’s voice, and the other person couldn’t hear me. I assumed this was due to the permission issue with the APK not having microphone access at all times (and also the microphone indicator not showing). Therefore, I kept the floss ims app open and answered an incoming call. I encountered the same issue, with the other person speaking and me being able to hear them, but I couldn’t be heard by the other person. However, there were a few differences in the case of incoming calls with the ims app open. Firstly, the microphone indicator showed, and secondly, the call state became “in call,” and a call timer started.

Please inform me if there are any additional details I should provide,

Thank you.

Did you check that the app has the microphone permission at all?

Yes, the app has microphone permission. The only available options are allow while using app and allow while using, I have granted the permission for allow while using app.

Edit: Sorry I meant to say the permission are allow while using app and ask every time.
