After connecting the Redmi Buds 6 Pro to an iPhone, you can choose where the call audio is played.
When receiving a call on the iPhone, you have the option to select between answering through the phone or the earbuds. You can double-tap the touch area of the earbuds to answer the call using them, or manually select the device on the phone's call interface. Similarly, when making a call from the iPhone, you can choose whether to use the phone or the earbuds for the audio. If no specific device is selected, the earbuds will be used by default for the call audio.
