This works on the series E phones. It may or may not work on the series II.

1. Press the Speaker key (do not use the handset).
2. Dial the Name Assignment access code and wait for the special dial tone.
3. Using the key pad spell the name. Press each number until the letter appears.
4. When the correct letter is displayed Press the HOLD key. Pressing the HOLD key will lock the letter in place and advance to the next position.
5. Repeat steps 3 and 4 continue to spell the name.

2) then press "#", "*", "#"
3) lift the phone, then hang up
4) press "Speaker"
5) dial "700"
6) press "hold"
7) enter the name (I'm still trying to find out how to leave a space, or use aother character that the same number key has... ugh"
8) press "hold" then "Speaker"

then make sure it saves it in the directory

To change the name I believe you have to go into the voice mailbox for that extension, and change the recorded name.
