Hi, It has gotten to the point we no longer can use either of our phones, new Samsung & new iPhone at our home. Constant dropped calls. Was bad before but getting worse. Yes both phones set the WiFi calling, installed a great Wifi extender, still nothing but garbled voices & then disconnected. Tired of paying all this $$$ for a service we can't use sitting in our own home. Tried every hint in support, nothing works. Now what?
