To create a voicemail box, go to the VOICEMAIL BOXES section of the dashboard and click on the 
symbol. On the next screen, enter a mail box number in the BOX NUMBER field and enter a pin number in the PIN NUMBER field in the SELECT A GREETING drop down menu, choose a greeting you have already recorded, or choose RECORD USING YOUR MIC to record a new sound file, or choose TYPE YOUR GREETING to create your voicemail box greeting with a computer voice. Enter one or more e-mail addresses to send voicemail notifications to, then save your settings.
NOTE: if you enter an e-mail address and leave the box checked that says ATTACH VOICEMAIL RECORDING TO EMAIL, you will receive an e-mail with the message left attached to the e-mail as a .wav file that you may play from your device.
