Call Waiting Ringtone in Android 10

[gauravsikhwal]

A week ago, I upgraded my Max Pro M1 to Android 10 AOSP .424 Version.
Call waiting function was enabled.

I got a normal telephone ring while I got a waiting call and that make me unable to hear voice of existing caller.

Earlier (Pie) Call waiting ringtone was used to be Beep sound.

I think this is an error caused by your local network provider. The wait order can only be changed when you subscribe to the service of your network operator
