Wifi calling

My video Tron Wi-Fi calling consistently cuts out after one or a few minutes on a phone call. When I was with Telus the Wi-Fi calling worked fine. I have superfast home Internet. 500 MB Per second down and 20 MB per second up. Is this Wi-Fi calling issue just a knownproblem with videetron or do you have any suggestions and tips that I can try to make my Wi-Fi calling more stable at my house? The calls are crystal clear, and I’m usually sitting in one spot, and then all of a sudden the call drops...pretty much always. Thanks for your help.
