English is not some peoples mother language.
Mine Neither - My 1st language is Hillbilly.
I went to my office and tried this out.
The form in the 3300 is "Multiline Advisory Messages". You can find it under "View Alphabetically" drop down box.
Find a blank line and edit the member.
Spaces in the line won't work so I put a '.' there.
Once you save it then you can go to a phone and hit the blue super key.
Say 'no' until you see "Advisory Messages" and say yes.
Then hit the "Next" button until you see the '.' then hit the "TurnOn" button.
Thats it.
