Porting Number Out of Google Voice

I want to port my daughter’s Google Voice (and Hangouts) phone number to an iPhone 11 on a real cellular service.

This used to be possible on the Google Voice legacy settings page where there was a Port link that would allow you to port a phone number either in or out of Google Voice. Now the link only allows porting in a mobile number.

How do I port OUT a Google Voice number to a new cellular service?

Nevermind … found this link:
