I added this as a comment yesterday instead of as an answer.
We had issues with this very issue. That is a Samsung S10e calling a Moto Z4 and the person on the S10e not being able to hear the Moto Z4.
I found that System Update 14 has a fix for this. This update did not update automatically for the 4 phones that we fix with this update yesterday. They had to manually go in and check for the update.
Update notes for System Update14
- Includes performance improvements that increase the stability of your phone.
- Addresses a one-way audio call issue on specific devices.
Go to Settings, System updates, Check for Updates.
System update 14 has a fix for this.
Hope this helps

I have the exact same problem. Only when my wife calls me she can't hear me. Everyone else that calls hears me fine.

What is the make and model of your phone(original poster)? Can your wife hear you if you call from another phone? Does she hear static or nothing? Are you on the same phone plan as her?
