you need to have either T-mobile or Orange as your cell carrier, those are the only two Kineto licensees that I know of (other than hardware preloads by Chinese phone makers Huawei & ZTE - not sure who you can use these phones with for wifi calling though)
If you have a phone designed for T-mobile or Orange in the last year or two, you probably already have the wifi-calling app (Smart Wifi) built-in anyway.
I could send you the app, but if you don't have both a carrier and phone on the very short approved list, it's not going to do you any good, because you won't get past Kineto's gateway.
So what phone and what carrier do you use, so we can even determine if what you are wanting is even currently possible?
here are the only phones that I know that will work with Smart Wifi (wifi calling):
