how to change voicemail greeting on live voicemail?

Hello abshchc,

You may wish to double-check to see if the voicemail greeting is set to the default or a custom one.

In the Phone app, select the Voicemail tab > Greeting > Ensure that 'Custom' is selected. You may then hit Play to hear a preview of the selected one.
