That’s nice. However, a simple headset with a boom mounted microphone is a vast improvement over a typical situation.
Even a cheap one from Koss. https://www.zipdx.info/product-review-koss-cs300-usb-headset/ We have a special service for use by conference interpreters like those who work for the UN. We have to occasionally review headsets to verify reliable, full-duplex performance. There are some USB audio interface chips that degrade microphone performance while in the presence of incoming sound. It’s a faulty echo cancellation scheme implemented in silicon.

You’d think that acoustic echo cancellation was settled science, and you’d be wrong. There are so many bad quality speakerphones and conference phones. Further, so many software engineers (yes, you Google!) think they have some special insight. Their stuff is just as bad as others. Worse because it can be variable. Bottom line is, if you must hear and be heard well…when it really matters….use a headset.

Dodgy speaker phone, poor plastic design of the phone, DSP not doing echo cancellation. Or too much end to end latency - if it is quick enough, you don't notice. Could be loads of things.
