Talking with someone non speaker phone option

When I answer a doorbell it’s great to be able to see them and talk to them, when talking to them it uses the speakerphone of the phone which everyone around me has to listen to me talking back and forth, it’s also hard to hear them if I have background noise around me. To have an option to switch to use non speakerphone mic and speaker on your phone (like a normal phone call) would be great
