No incoming call audio if audio is playing

[pmterp]

If I have audio media playing via a podcast app or audiobook (I tried with multiple apps) over a Bluetooth connection and a call comes in via the 3CX app, the media is paused and the Drop/Answer buttons are shown.
If I answer the call by either pressing the headset button or pressing the Answer button on screen, I do not hear the incoming audio from the other party but they can hear me.
I can tap the button in the app to switch audio to the handset, then again to speaker, and then again to Bluetooth and then I'll hear them.
I've tried with 2 different headsets, one is Sennheiser and the other is a no-name brand off Amazon.
It is 100% reproducible for me.
I'm running the current beta 16.7.4 on a Pixel 3 with all the latest Android updates.
I've also uninstalled and reinstalled the app and get the same result.

Is this a known issue/limitation or is there something I can do about it?
Since it is reproducible, I'm happy to capture logs or test theories.

Firstly, if not already, do make sure that you are running the latest Beta version which is currently 16.7.4.74. If you are already or you upgrade to it and the issue persists, try toggling "Telecom API" on or off depending on what it is already set to and check to see if there is a change in behavior.

The setting can be found in "Menu >> Settings >> Advanced".

@pmterp
If the issue you described still persist:
1. Go to Settings
2. Go to Advanced
3. Enable Verbose Logging.
4. Exit the application.
Make a call and answer and immediately send us the log report (Settings/Advanced/Send Log Report)
Thanks!

@Vali_3CX I tried toggling the feature ChrisC recommended and had other issues like I couldn't answer by pressing the headset button so I reverted back to default (having it checked).
I was able to recreate the issue with verbose logging. Do you want me to PM the file to you or open a support ticket?
