I don't see that the service has improved all that much. I'm still running the beta program, so I'm currently on iOS 9.1 beta 5 I think. However, I don't really do calls a whole lot. It's been a few days according to the call log.
I can only watch the bandwidth usage when I'm on the phone at my desk. It tends to start in the low 40kbps area and climb up from there. I've not seen one hit triple digits yet. We do have a captive portal and honestly I've not tried wifi calling when stuck in there yet. If it uses DNS it will break at this point in time, but if they have a list of hard coded IP address in the phone software it will still work. Our captive portal is strictly DNS smoke and mirrors. Now that you mention it, I do remember it asking for an address and giving me a warning in ALL CAPS for 911. -Christopher On Oct 16, 2015, at 3:50 PM, Smith, Todd <todd.sm...@camc.org<mailto:todd.sm...@camc.org>> wrote: Christopher, Those are some great answers and I apperciate the input! 1) Has the call drop percentage improved as the service is maturing? 2) 65Kbps is much better then I was expecting, so that it good. Do you notice many spikes in bandwidth as the call is in progress? 3) Do you have a splash page or captive portal on your open wireless? Does that interfere with AT&T Wi-Fi calling in your experience? 4) I agree that E911 is going to be a serious issue. On AT&T Wi-Fi calling FAQ, the user has to specify a location that they would normally be using Wi-Fi Calling for E911 purposes. It is also going to try to get location information from the Wi-Fi networks to locate the call, but it will default back to stored location as a last result.

I'm honestly not surprised to hear that they are going to push wifi calling and nothing else. They want to drop all cellular service other than data, long term, in my opinion. I have AT&T myself, and ran the iOS 9 beta from the beginning, which got me early access to AT&T wifi calling. Needless to say, it has not been a pleasant experience. Calls drop all the time. For our wireless we have not had to do anything. Calls just work without opening inbound ports (we don't limit much going outbound). My calls run about 65kbps. The pain point is something you've already mentioned - roaming. If at any time you roam from wifi to cell and there is no VoLTE service in your area, the call dies. We apparently don't have VoLTE in Chattanooga, TN. If I stay in my office I can usually hold a call, and roaming from AP to AP is sometimes ok. Sometimes the roam between APs is enough to drop the call. I've also noticed that if I get more than 2 cell bars, the phone will want to go off of wifi calling on its own. Even at home where I only have 1 AP and can be sitting 15 feet from it, I'll drop calls because my phone decided to roam back to cell during a live call. To directly answer your questions: 1. I don't plan on doing anything special. We have enough free bandwidth to handle a large number of 65kbps calls. 2. Mine have been 65kbps or there about. 3. We run both frequencies, but my phone tends to stay 5ghz. I don't think we would change anything to support wifi calling. 4. I'm not sure how we will get this across other than to let our helpdesk know what to tell people when they call in about it. We'll be looking into this more I'm sure. 5. I'm a little surprised that carriers are being allowed to run calls over end user networks. 911 is a big deal, and if our wifi is up enough that the phone can do wifi calling, but there are issues going on to prevent calls, who gets blamed here? In an emergency, it's too much to troubleshoot what's going on and figure out that you have to cut off your wireless to get a call through. As far as I know, there's nothing we have to do in terms of uptime or anything. -Christopher ====================================================================== CONFIDENTIALITY NOTICE: The information contained in this message may be privileged and confidential.
