I sound like a robot after 5mins, not before, on WiFi calling

Hello.  In the last couple of months a new problem has arisen when I'm speaking to someone on WiFi calling.  After a few minutes of working well I suddenly sound like a robot.  They still sound v clear to me.  The only solutions are to either for me to call them back on WhatsApp or for me to move to a place where I can connect directly with the mobile signal.  Neither is good and the second one takes me away from my computer which is a pain because I'm trying to work.  I'm using the same MotoG50 phone as I've had for a couple of years.  Anyone any ideas?  Thanks

Hi @Cris100 

It is becase your WiFi is poor. What router and what internet service do you have.

Are you connected to WiFi 2.4, 5 or 7. 

Thanks
