iOS 12 Wifi calling stopped working

Upon upgrade to iOS 12 today WIFI calling no longer works.  I checked all the settings and it's configured correctly.  It worked perfectly prior to the upgrade.   The upgrade installed new carrier settings 33.1.   Any tips or is this a bug?

Re: iOS 12 Wifi calling stopped working

My carrier settings are version 34.0

Upgraded to ios 12.1 today - still working.

Try upgrading to 12.1 and the carrier settings will likely update as well

Re: iOS 12 Wifi calling stopped working

In the latest public beta, which I almost refused to install because of this debacle, the latest carrier update is bumped to 34.5.2. Without release notes, impossible to know what’s changing, but the reality is it is changing. I feel like I’m playing Russian roulette now every time I update iOS. WiFi calling is a disaster zone.

Re: iOS 12 Wifi calling stopped working

I’ve tried all the tips to fix this issue & it will work for a couple of phone calls then stop working when I change Wi-Fi signals. Very frustrating!

Re: iOS 12 Wifi calling stopped working

Same issue here with the following

Iphone X

At&T 33.2 "Voice & SMS"

 

I work offshore so this is the only way I can communicate to android users over wifi. Frustrating that it isn't working. I can randomly get a text to go through but I am not understanding why it works sometimes. Restarting the phone, placing in airplane mode, etc.. nothing allows me to text/call non iphone users.

Re: iOS 12 Wifi calling stopped working

My issue has been resolved and all I did was install the latest iOS update with carrier settings (34.0).

Re: iOS 12 Wifi calling stopped working

iOS 12.1.1 is close to being released and will bring with it a new release of carrier settings. It's a moving target and am skeptical stability will hold.  Let's see what happens.

Re: iOS 12 Wifi calling stopped working

My new IPhone XS on IOS 12would not keep a connection to the WiFi calling.I tried all the fixes recommended by Apple & ATT- but nothing worked. On my previous IPhone 6s on IOS 12 my WiFi calling connection worked for the last year. Prior to that I was using an ATT micro cell & it worked pretty good in most( but not all) of my house. Without WiFi cellular or the micro cell, I either had no service or 1 bar with a terrible unreliable  connection. I think that when I bought the IPhone XS 10 days ago the reason the WiFi connection kept dropping or not connecting is that the antenna on my new XS was much stronger than my 6s , so that the connection would drop off my WiFi connection onto the cellular connection, but in most of my house the cellular connection was still weak, so horrible unreliable service . But, it’s solved now. I re- installed my micro cell and I have 3-4 bars in my entire house now . Kept the WiFi calling on as a back up, but I don’t think it will ever come on again . While the micro cell cost $ to buy it, well worth having good cell service in my entire house.

Re: iOS 12 Wifi calling stopped working

I was under the impression att favored WiFi calling and dropped support of microcell. 

As I’ve written elsewhere, if running a call where there’s a good chance 4G radio will take over and the call started on HD Voice, the call will drop. Not a very good switchover design.

Re: iOS 12 Wifi calling stopped working

I had this same problem and solved it today. this does *not* seem to be an AT&T problem but, instead, has to do with the way that your wi-fi router is configured.  

 

you need to open ports 123, 443, 4500 and 500 -- done through configuring 'port forwarding' on your wi-fi router -- and allow those ports to pass to the specific AT&T device(s) that you want to use for wi-fi calling.  AT&T support gave me these port numbers and then I configured the appropriate information into my ASUS router (I have Comcast internet but don't use their wi-fi router) and it worked immediately.

 

good luck!
