Why doesn't SIRI make calls on AT&T WiFi iPhone 6s ?

That is a problem! Essentially, it sounds like a Siri software issue that has not been addressed. I'm saying that because both you and your wife are having the same issue.

Two things you could try:

1) Resetting your network settings - This will trash all wifi network data, so you will have to re-register your wifi passwords

General, Settings, Reset, Reset Network Settings

2) Turn on LTE Voice. Although WiFi and Cellular networks are two separate things it is worth a try. In General, Cellular, Enable LTE, check off Voice& Data. There is a small chance that may do something.

At least you can still make calls manually! Good luck and hopefully an update comes out that fixes your Siri problem if the items above do not resolve anything.

I have a 6s Plus and I cannot get Siri to dial calls at all. She will do everything else except that. Checked all the obvious settings. I did have ATT WiFi enabled and Number sync. I disabled it all and she still won't dial.

Yes Siri won't dial under any circumstances. Looks like it's a 9.2 issue from all the reports popping up now. I disabled Siri and I'm using old Voice Dial until it's patched.

It doesnt just affect the 6S, I have exactly the same problem with my 5S. I to have been through the; backup, reset, restore routine with Apple support but with no success. I was also told that the phone has probably got a hardware fault and needs to be checked out by the 'experts' at an apple store. But reading the above suggests that is a waste of time. I have just updated to 9.2.1(13D15). It seems that I can use SIRI for everything except making a Call. I am in the UK and cellular provider is EE, their tech support recommended contacting Apple support.

Same issue here on iPhone 6 AT&T. I also have the s problem on my iPad Air

I am also having this same issue, and I am on Verizon. I have:

• shut the phone down and restarted
• reset the network settings
• tried only using cellular connections
• tried using multiple WiFi networks

It's as though she cannot access anything related to my contact list, either. If I ask for phone numbers (just get the number of a contact, not dial it), emails, etc., there is a long pause and she says something to the effect of "there's a problem." (yeah, no **** 😝)

Everything else works, though... she will check the weather, conduct web searches for info, etc... just the contacts seem to be a problem.

Any help would be appreciated. This isn't a good feature to be missing if I have to make a call while driving...

I have recently noticed that my Ipad (not cellular) and Iphone 5S have become 'linked' by WiFi presumably as a result of IOS updates. I now receive messages that automatically come through to the Ipad and also that I can answer calls on the Ipad. So I tried using Siri on the IPad to make a call through my iphone and guess what? it works fine. So answer this one Apple, how come I cant use Siri to make a call direct from my iPhone but can make a Siri call 'through' my iPhone from my iPad

Same thing here using T-Mobile wifi calling. Siri will not make calls unless on the cellular network. Downloaded iOS 9.3 beta 5 to see if there is a fix and Siri still does not allow calls while on T-Mobile wifi calling

Siri doesn't recognize WiFi Calling as a valid cellular connection. It's a bug.

If you're having this issue, please submit the bug report to Apple via:

The more people that submit this problem to Apple, the more likely it is to get fixed some day.

Thanks!

It looks like Apple finally fixed this issue in iOS 10 whoo hooo! Just made a call with Siri with Airplane mode eneabled and Wifi Calling.
