A couple of things to note when using WiFi Calling

At launch, there are a couple of things which might make your call experience over WiFi Calling slightly unusual. Firstly, you’ll hear the international dialling tone when both parties are using WiFi Calling. Secondly, when a call is put on hold, the person on hold won’t hear the hold beeps. There will just be silence. We’re working to resolve these quirks, but it shouldn’t affect the quality of your service.
