Q: AT&T Wifi calling instantly drops incoming calls on 6s
Hello:
Activated my new 6s today and enabled WiFi calling via AT&T.
I can make outgoing calls on AT&T wifi, but incoming calls ring for less than a second, are dropped, and show up as missed calls. The person calling doesn't get voicemail and instead gets a fast busy signal
My brothers iPhone 6 works fine on the same network and can make and receive wifi calls.
Any ideas would be much appreciated
iPhone 6s, iOS 9.0.2

After 4 hours with two separate AT&T tech support folks, this was solved with a trip to the local AT&T store. Spent two hours with a really knowledgeable sales guy - we recreated the issue, switched out SIM cards, switched out phones and tried adjusting backend provisions and nothing fixed this issue. We had given up and were about to leave the store with guy basically saying "Wait it out, and it might get fixed as AT&T rolls out wi-fi calling".
The very last thing he tried finally worked: he contacted AT&T internal tech support who reset my account registration and OTA activation and that finally solved the issue.
