My iPhone detect the Mac mini as an audio output calling in 11.3

I don’t advice that before
Is it a AirPlay 2 feature?

I was near my Mac mini 10.13.4 beta with my iPhone SE 10.3 beta and could see as the icon that shows options of audio output looks different as usual

Pushing for toggling shows three option: speaker, iPhone and “Mac mini”

If I choose Mac mini it doesn’t work. Try for a seconds and finally select iPhone output

Could be a beta bug
Could be a incipient beta feature of airplay 2?

When I play music in iPhone “Mac mini” doesn’t shows as a output option only during a call

I think you have 'Calls on other devices" on, this feature permits to answer a call from another iOS or macOS device (or transfert a call from one to another since 11.2)
See this video from Macrumors

You're right

Whats the different with the old feature of show the calling in mac when you get it. I think that it was presente in iOS 10 or 9. If I have the phone in my room but working in Mac I get a notification in desktop of Mac to hang on the call
