Quick responses no full duplex

I can’t hear voice responses from the wireless eufy doorbell. No full duplex so no way of knowing if they heard the quick messages?

Yes it’s stupid, if there is any audio coming out of the doorbell it seems to cut out the microphone. I have learnt while talking to people to only turn my Mic on to talk then turn it off again to listen to them otherwise if you leave your Mic open the audio can sound choppy and both parties struggle to hear each other.
