Here are the steps (we have different models, but it should be the same options):
1) Pick up the handset of your phone and press the voicemail button.
2) Don't enter your password yet. Press the CALL VM button.
3) Then, enter your password followed by # after the prompt. Default is 1234. Listen to the options spoken through the handset.
4) Press 7 to change voicemail options.
5) The three options below are the most common selections. Choose them to record a personal greeting, change pw, and record your name.
1 - Record personal greeting
4 - Change pw
6 - Record name
6) The system allows you to review your message/name recorded. If you messed up and want to re-record, follow the prompts to do so.
