Thanks to Hunter Fuller who relayed Jason's questions. I have been piecing together information from muliple sources and there isn't a whitepaper that I have found yet.
1) For AT&T, it is only 4 phones usable for Wi-Fi calling and it has be configured by the phone as well as a correct service plan. 2) I don't know, but it is not something that I am happy. 3) Call minutes, No. SMS are billed according to user's plan. 4) I don't know, but I hate that fact that it looks like our organization is going to on the hook for something.

SMS? * To echo what Christopher said, what about 911 etc, who is responsible for call quality and completion? * What about geolocation and emergency, does the wifi enhance it or obsfucate it in any way?

In seems, that Wi-Fi calling is the moving forward strategy for AT&T for poor cellular signal and presumably other carriers. I wasn’t in the meeting but I am confident that it has been reported accurately. Does this sound like anything that anyone else has heard? If so, how are other institutions handling this? It seems silly that our organization which is in the planning stages for a Wi-Fi wireless upgrade anyway would build in the necessary upgrades to accumulate cell carrier backhaul traffic for no compensation whatsoever. As usual, my job is to do or die, so I am trying to see what others might have done and if possible start a line of discussion to reason out the best way to handle poor cellular coverage in both older buildings as well as brand new LEEDS certified buildings. 1) Would you create a new SSID for cellular traffic with QoS enabled and open to the Internet with UDP 500 and 4500 open as well as more normal ports? 2) I can’t find any solid reference that details exactly how much bandwidth per call. I have literally read in the last couple of hours, everything from 2.5Kbps to 1Mbps to a general consensus from 60-128Kbps per call. 3) 2.4Ghz or 5Ghz or both? 4) Much of the discussion of seamless handover from cell to Wi-Fi involved HD Voice which seems to be provisioned as part of VoLTE and only available in some areas; i.e. not my coverage area. How to communicate to your normal users and any public that uses your Wi-Fi that when they switch between platforms; the call will be dropped? 5) Would we be responsible for maintaining redundant Internet connections just to support cell calls? Is there any requirement that would state that since we are providing cellular infrastructure that we are responsible for a certain minimum SLA? Is there any other questions or comments to think about?
