Does the Windows Lumia 640 XL for AT&T come capable for wi-fi calling?

does the Windows Lumia 640 XL for AT&T come capable for wi-fi calling

My T-Mobile 640 Go Phone could be switched to wifi calling but I cannot figure out how to accomplish this with the AT&T 640 XL versions so I thought it best to ask if the phone was even capable.

I haven't heard anything about the AT&T 640 xl being able to make wifi calls, so I doubt it. The T-mobile variant has wifi calling as part of the firmware.
