Wifi Calling and iPad/Yosemite continuity

[LixLev]

Can I ask any USA users who use the T-Mobile WiFi Calling feature, if you make a call using your iPad or Yosemite Mac, and your phone is on wifi, does the call still route through Wifi Calling or does it use the cellular network?

If I haven't explained the question clear enough, just say and I'll try and rephrase it.

If you have wifi calling enabled, you cannot make phone calls from your Mac or other iOS device. It's one or the other.

Thats annoying, anyone know why that may be? Is it a technical thing?
