Setting Up Your Mailbox

The first time you log into your mailbox, you will need to record your name and a personal greeting.

The name recording is for the dial-by-name directory, so when someone enters the first three letters of your last name, it will play back your name recording.

The greeting plays when your mailbox is reached by a caller. It is very important to make a custom message, as many callers will not leave messages at mailboxes that have generic greetings.

Then press 1 to record an alternate greeting.
When prompted for the greeting number, press 2 for your next alternate greeting (1 is your default greeting).
After your recording is completed, select the active greeting by selecting option 3 in the greeting's menu.
