Dropped calls in my house

I've done it both ways.  Calls drop either way.  I am stationary in my home office, sitting in my chair.  Calls start off great, and then several minutes into the call, either I can't hear them at all, they can't hear me at all, the call drops all together, or a combination of all three happen.  I don't move at all, and the wifi signal is strong in my office, I am constantly on the internet so I know that functions well

Add me to the list of people whose wifi calling drops.  I am forced to use wifi because, despite your claims, the cell signal does not cover my property.  New phone (Oneplus 7T), all updates (10.0.16), gigabit fiber, FIVE access points.  This usually, but not always, happens when I am moving.  This tells me that your wifi calling is anything but the state of the art.  Other than moving to a different carrier, what can I do to make calls with my cell phone in my own home?

This is happening to me too, and it is infuriating. I have a 1Gb symmetrical fiber connection, with a WiFi6 router 15ft away from me. No other device (be it PC, Mac, Firestick etc...) loses connectivity, but this p.o.s T-Mo service drops calls randomly. It's enough to make me want to jump ship because I am forced now to take calls over skype on my PC as my phone cannot be relied upon.

And no, I am not moving amount. Instead of spending money on shi**y tuesday promotions how about actually properly enhancing your IT infrastructure???

Are you using WiFi Calling? If you start a phone call on WiFi and move away from the router, the call will drop.

Well, if your router doesn't prioritize WiFi Calling, you could drop calls because of your internet connection saturates.  As for when you're not using WiFi Calling, it might help to know where you're located and what phone you're using. 

They could also try putting their device in airplane mode and then enabling WiFi Calling to make sure it isn't trying to switch back to a spotty cell connection.

I am located in Chicago, Northwest side, and I am currently using a Samsung S10, but the issue was the same with my Samsung S7 edge as well

It might be that you're in an area where band-71 (600 MHz) has not yet been installed and you're relying on band-12 (700 MHz) for indoor service. Band-12 is pretty limited and may become saturated. However, this does not answer why calls fail when you're on WiFi. I'm just grasping at straws. Don't really have a clue why this is happening.
