I have IPhone 11 and after upgrading to 15.4 Siri will say “ Calling XYZ. “ But does not really call and the icon keeps on pulsating
tried calling by the phone number also by dictating all numbers one by one
Go to Settings. Tap Siri & Search. Turn off Listen for "Hey Siri" and then turn it back on. When the Set Up "Hey Siri" screen appears, tap Continue.
If "Hey Siri" isn't working on your iPhone or iPad - Apple Support
