How does CMF Buds Pro 2 handle incoming calls when connected to two phones?

1. When the earphones are connected to two devices, and neither device is in a call state:
1) The earphones will output the ringing sound from the device that's receiving a call.

2. When the earphones are connected to two devices, and one of the devices is already in a call:
1) The earphones will play the incoming call alert and the earphone buttons will prioritise controlling the device that's receiving a call. If the earphones hang up the current call, the audio channel will switch to the other device that's receiving a call.
