I wouldn't hold your breath for wifi calling. I'm still waiting for them to enable Volte for my Nexus 6. I live in a area that has it, but I can't use it because it's not a att branded phone. Maybe if enough people complain, they'll enable it for us.
My wife just got an email from AT&T yesterday and forwarded it to me this morning saying that WiFi calling is now enabled.
here is the email:

AT&T Customers Can Make Calls Over Wi-Fi on Select Devices Beginning Oct. 8
http://www.att.com/shop/wireless/features/wifi-calling.html
With the FCC recently granting AT&T’s waiver request related to certain deaf and hard of hearing technology,
AT&T customers will be able to use Wi-Fi in addition to the traditional cellular network to make and receive calls while in the U.S. beginning Oct. 8.*
Wi-Fi Calling is a complement to AT&T’s already great network coverage. Along with a network that covers more than 99 percent of all Americans, our customers now have an option for making calls in areas where a cellular signal is tough to get – such as a home or office with dense building construction. Make and receive unlimited domestic calls within the U.S., Puerto Rico, and U.S. Virgin Islands at no additional charge. International long distance rates apply for calls made to international numbers.
Once set-up, your phone will use Wi-Fi Calling automatically in places where you have limited or no cell signal, but you do have a Wi-Fi Internet connection.
In order to use Wi-Fi Calling, customers just need a compatible device with iOS 9 installed, a postpaid wireless account set-up for HD Voice and a Wi-Fi Internet connection. This includes a Wi-Fi connection set up at home or the office.
Wi-Fi Calling works in the background, allowing you to make and receive calls like you would on the cellular network. Since the service is built-in, you have the same telephone number and access to your contacts without having to add them to a separate app.
Wi-Fi Calling is easy to set-up and, in most ways, making a call over Wi-Fi is a lot like a regular phone call. There is no additional charge on calls to U.S. numbers. See below on how to install. I would recommend testing a few lines before activating on all lines.
