According to the 9to5google report, the new Assistant change will restrict that calling capability to numbers saved in your Google Contacts. Some users reported that the feed tab of the Google Home app has started displaying an “Important change to calling” card that links to a support article.
Starting in December of 2021, this feature requires you to:
- Set up Voice Match and turn on personal results for the Google Assistant-enabled devices you want to make calls from.
- Have or add the number you want to call to Google Contacts.
- That second requirement does not apply if you set-up Google Fi or Voice: Assistant settings > Communication > Call Providers. For everyone else, their Home
- device will ask them to save a new number in Google Contacts before Assistant can dial.
