WiFi Calling

[SDAVE]

Does anyone else have this issue?

I activate AT&T WiFi in Facetime on my MacBook Pro and then on my iPhone 6s+ with iOS9....it works perfectly from the MBP for a while and WiFi calling is clean, but after a while it goes back to regular "Call using iPhone" which is not as good as WiFi calling. I have to reactivate it every time with "Upgrade to WiFi Calling".

Trouble with WiFi Calling is the it only switches to WiFi Calling when the signal is pretty bad. As the signal fluctuates from pretty bad to good it may switch back to cellular even during a call. I was thinking for a while that once it locked on to WiFi Calling it would just stay there but sadly that isn't the case.

On AT&T rep told me that if you turn on Airplane mode and then switch WiFi back on that it may help keep it in WiFi Calling. I've tried that with mixed results.

On the other hand it works pretty well 95% of the time.
