The feature works fine, I had to turn off the mobile network for it to kick in as it tries to stay on LTE as default.
I noticed that on the notification panel has a new icon to enable and disable WiFi calling, what I hate is that it resets to the default position after a reboot. Other than that it runs fine and I'm happy to have security patch for June 2016!
Just unrooted, back to stock, and then upgraded to MM just for wifi-calling today. However, I don't see that option anywhere. I read somewhere that it's a toggle on the notification bar. What am I missing/not seeing? This is for AT&T and software version says H81020n with no new further updates to install.
That sucks... I do not notice any big problems, but it does drive me crazy to have the WiFi Calling icon in the notification bar place itself after a reboot.

The notification panel icon rest is really pissing me off. It's thing like this that make me miss my stock Nexus. I'm going back to Nexus when the next one comes out.
