If a call is received in the example app GitHub - sendbird/quickstart-calls-ios: Sendbird Calls for iOS sample, guiding you to build a real-time voice and video calls quickly and easily. whilst having a bluetooth headset connected then the bluetooth headset gets disconnected and the audio starts coming through the iPhone (if you have your air pods connected and receive a call you would expect to continue the call using the air pods). Whats more concerning is that afterwards there is no way to choose the headset as it does not show in the AVRoutePickerView. Any thoughts on how to fix this @mininny?
@J_sung_0o0 Any thoughts?

Hi,
Thanks for letting me know the issue and I checked it from quickstart. I will get back to you as soon as possible.
Hi, @David_K
Could you please clarify few more things? 
What is the iOS version of the device you tested on? We’re seeing similar problems on iOS 14, and it would be helpful to know if this issue occurs on devices with different iOS versions such as iOS 13.
iOS 14 and 13, tested on iPhone 11, 12 Pro. @J_sung_0o0
Thanks for letting me know the versions. Does iOS 13 device show same issue?
Yes.

Hi, @David_K
Calls iOS SDK 1.5.3 version has been released just before. Please check the issue again with the latest version and let me know the result.
Issue seems fixed in 1.5.4, thanks.

@J_sung_0o0 I’m having a similar issue on Android 12 with the Chrome browser. The connected bluetooth earphones just shut off when a call is initiated, and uses the phone’s speaker/mic instead. Any thoughts? Thanks!
