Wifi Calling falling off network

I'm really frustrated. for the last month I can no longer receive phone calls. neither can my wife or kids. If we disable wifi then we can make a call which then seems to put our phones back "on the network". however within a few hours to a day they all fall off the network and we can no longer receive calls. Sometimes we also cannot make a call which could be dangerous as 911 won't work. 

Unfortunately cellular calls here drop constantly so we cannot use cellular services for more than a few seconds at a time. One time i reached out to support and they told me they were "working on a known problem" but then when I tried to reach out recently the agent acted like the problem was with my phone. And then it was the router. But wifi calling works just fine so long as you first make a call over cellular first. Really wish T mobile had US based support as the language barrier makes it very difficult to communicate.

    If you originate the call on cellular, it will keep that call on cellular even if you enable WiFi and WiFi Calling turns on.  What device are you using?  Is your device up to date, including all syatem apps that might rely on WiFi Calling? 

    WiFi Calling needs a stable and reliable internet connection of about 20Mbit up and 20Mbit down to ensure you get a solid quality call experience in my opinion.  Not all routers are as friendly to WiFi Calling for T-Mobile as Asus routers are.
