I realize that there is already a lengthy thread about wifi calling with Google Voice. But I need to start at the very beginning. We moved our offices to a former school and the concrete block walls make for poor reception with any network. I'm missing calls while in the building regardless of the MVNO and I've used 3 of the 4 networks.

Anyway, we have a strong wifi signal, so I need to figure out how, if possible, I can do wifi calls. Yes, I know I could be using Hangouts and if that's the only solution, I'll accept it. I would prefer to stick with GV, just because I'm familiar with it.

I have not received an email to try the beta version, so am I able to somehow get the version of GV that allows wifi calling? I don't see an option to enable wifi calling in my settings.

I have GV build 2018.45.220165759 on a Moto E4 running Android 7.1.1.

Thanks in advance for any suggestions.
