How can I tell if WiFi calling is working?

[gkendall43]

I just got my 6s on AT&T and turned on WiFi calling. How can I tell if it's working? I see 2 bars of signal strength for calls and it says "AT&T WiFi".

Thanks.

Hello! The "AT&T wifi" label indicates that your phone is using wifi for voice calls.
