As of iOS 11.2, when you are using a Bluetooth headphone and receive a phone call, the button that you use to pick-up the phone call, determines which device is used for the audio.
If you pick-up the phone call with the green button on the iPhone display, then all the audio will be handled by the iPhone microphone and speaker (and not with any connected Bluetooth device).
If you pick-up the phone call with the call pick-up button on the Bluetooth device (headphone or speaker), then all the audio will be handled by the Bluetooth device.
If the person that is calling you cannot hear you – or the other way around – it may be possible that you picked up the phone with one device and are talking via another.
Use the audio icon on the iPhone display during the phone call to change the audio device.
