2 way audio adjustable mic and speaker loudness

When i speak too someone outside like the whole street can here you, this could be a big downside of you are telling a delivery driver too put the parcel in a safe place till you are home.

And sometimes the audio for the person speaking outside is a tad low.

The 2 sensitivity options would be great.
1 for outgoing speaker volume customisation
And 1 of mic sensitivity.

i have the same problem. the whole world can hear me when i answer the door
