WiFi calling- other person can't hear me but I can hear them

I have been having exactly the same issue.  No problem with Wifi Calling untill about two days ago.  Now when I call or receive a call, they can hear me for a minute or so then they can't hear me or I break up.  I've restarted router and phone. Still no joy.

Does your phone show WiFi-calling or VoLTE/4G-calling when this problem happens?

Phone shows wifi calling with full wifi. Sat in same room as router.
