Findings

I found out that this only occurs when the app is using call kit and accepts the call by pressing the accept button on the device.
Bluetooth earphones work when call was accepted using Bluetooth earphone answer button.
I ran the VideoCallKitQuickStart and it seems that it is also encountered there.
I found a similar issue way back in 2018 - #236
This issue is similar to #468 with a difference of user was connected to a room first before connecting the Bluetooth earphones. I've tried this code but it does not fix the problem.

@kheldiente,

First off, I want to apologize for not getting back to you on this sooner. Are you still seeing this issue?

I have just tested this using the CallKit QuickStart, the latest TwilioVideo release (4.2.0) and my AirPods. I schedule the notification for the incoming call, lock the device and wait for the notification. I trigger it to simulate an incoming VoIP notification and get the CallKit incoming call UI. I accepted the incoming call on the iPhone and it joined the room and audio was flowing to and from my AirPods.

Can you take another look at this and let me know if you are still seeing the issue? At the moment I only have AirPods to test with. Were you seeing this with a particular bluetooth earphones or was it across various ones?

Again, sorry for the long response.
