Custom greetings for Take a Message
The Pixel’s Take a Message feature that answers calls on your behalf and lets you view live transcripts is now adding custom greetings.
Once available, you’ll be prompted at the top of the Home tab to add “A personal touch on your missed calls” that are handled by Take a Message. You can also access custom greetings later by going to Settings > Take a Message.
This opens a new Greetings page where you can see the Standard greeting — “The person you have called is not available. Please leave a message after the tone” — and record new ones.
The recorder uses a Material 3 Expressive interface that lets you capture up to a minute‑long clip. When finished, tap Pause and then Save at the bottom corner.
You can store multiple recordings in Greetings, with the active one marked by a star. Use the three‑dot overflow menu to Set as default.
Custom Take a Message greetings are rolling out with version 216 of the Phone by Google beta. It’s not yet in the stable channel.
