Yes it did -

Set up voicemail

The first time you tap Voicemail, you’re asked to create a voicemail password and record your voicemail greeting.

1. Tap Voicemail, then tap Set Up Now.
2. Create a voicemail password.
3. Choose a greeting—Default or Custom; if you choose Custom, you can record a new greeting.

The only thing that I can think of that is missing from that is to tap Record. I already have a greeting that I don't want to mess with so I don't want to go into the process to view and describe every step, but it's straightforward and if you can repeat it if needed to get it right.

The visual voicemail settings will not hold a custom recording even after tapping the Save button. As soon as the Save button is tapped it will automatically revert back to the default recording. Tapping play in the Custom view plays the factory default message again. Either the phone is defective, which I doubt, or the software is corrupted. However, going into audio voicemail settings works and the custom recording can be saved. The inconvenience of having to place the phone up to the ear makes it clumsy to do because there is no choice in the Call mode of voicemail to select a speaker option. It seems to be an obsolete way to have to do a custom recording but was the only method I was able to discover that worked. The device engineers should take a look at this and come up with something better or provide some reasoning as to why it was designed this way, so as not to confuse everyone.

I also have a brand new iPhone 15 max Pro Max and my personal voicemail greeting will not play when someone calls me - not even the default greeting will play. Went thru all the steps multiple times - I can play the greeting for myself and save but it will not work when I get a call.

These instructions do not discuss any steps on how to record the greeting and save it. Do you have any other ideas on how to save the personal greeting.
